Water

After planting, the crepe myrtle should be immediately watered thoroughly, and then watered thoroughly once every 3-5 day for 2-3 times. Within two months after planting, if there is no rainwater, they should be watered once a week. Covering 5 to 10 cm of chopped wood mulch half a foot around the trunk to help maintain the moisture of the roots and reduce weeds. When a plant begins to blossom, 5 to 8 cm of new mulch should be used in each spring. The crepe myrtle are very drought resistant. After root systems are formed, they only need to be watered once or twice a week during the dry and hot flowering period. In ordinary time, they can be watered once one or two months and it should be ensured that the soil is dry before watering each time, and watering in the evening or at night should be avoid to prevent fungal diseases.

Ground Crepe myrtle watering

If Crepe myrtle is planted outdoor with adequate rainfall, it may not need additional watering. When Crepe myrtle is young or newly planted, make sure it gets 1-2 inches of rain per week. As Crepe myrtle continues to grow, it can survive entirely on rainfall. Only when the weather is too hot, or when there is no rainfall at all for 2-3 weeks, then consider giving Crepe myrtle a full watering during the cooler moment of the day to prevent the plant from suffering from high heat damage. Additional watering will be required during persistent dry spells.The age of the plants matter. Lack of water is one of the most common reasons the newly planted ones fail to grow. After they are established, you need to ease off the watering schedule.

When you live in a hot climate, you might want to water once a week.Consider the amount of rainwater on the plant and ensure not to add to it to prevent root rot.You may not need additional watering of the plants if there is a lot of rainfall.Crepe myrtle generally grows during spring and fall. When they are outdoors, you need to add mulch about 3 to 4 inches deep to conserve more water. Usually, the Crepe myrtle will need less water during the winter. Since the Crepe myrtle will drop their leaves and go dormant, Once your Crepe myrtle growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Crepe myrtle can rely on the fall and winter rains to survive the entire dormant period.

Potted Crepe myrtle watering

The Crepe myrtle needs outdoors come from rain, with only persistent dry weather requiring watering. Throughout the spring and fall growing seasons, the soil needs to be kept moist but not soggy, and alternating dry and moist soil conditions will allow the Crepe myrtle to grow well. Throughout the summer, hot weather can cause water to evaporate too quickly, and if there is a lack of rainfall, you will need to water more frequently and extra to keep it moist.

The Crepe myrtle likes deep and infrequent watering. You would want to soak them in a gallon of water each time, especially when they are planted in pots. The water storage of flower pots is limited and the soil will dry out faster. Watering is required every 3 to 5 days when living in a cold region. Water it early in the morning when the soil is dry, outdoors or indoors. You can also determine if watering is needed by checking the soil inside. When the top 2-3 inches of soil is dry, it is time to give the plant a full watering. During hot days, you may need to check the moisture daily, as the heat can quickly dry out the soil in the pot.

Underwater and overwater

Always check the moisture levels at the pot when you have a Crepe myrtle indoors. Avoid overwatering indoors and see if there are signs of black spots. If these are present, let the soil dry in the pot by giving it a few days of rest from watering.

An overwatered Crepe myrtle can start to have leaves that turn yellow, drop off and wilt. The plant can also look dull and unhealthy, with signs of mushy stems. When they are beginning to show these signs, it's best to adjust your schedule whenever possible.

Overwatering can lead to root rot being present in your plant. If this is the case, you might want to transfer them into a different pot, especially if you see discolored and slimy roots. Always prevent root rot as much as possible, and don't let the soil become too soggy.

You should dig a little deeper when you plant your Crepe myrtle outdoors. When you check with your fingers and notice that the soil is too dry, it could mean underwatering.Adequate watering is required to help the plant recover.

The wilting can also be a sign of under watering as well. You might see that the leaves begin to turn crispy and dry while the overwatered ones will have soft wilted leaves. Check the soil when it is dry and watering is not enough, give it a full watering in time. Enough water will make the Crepe myrtle recover again, but the plant will still appear dry and yellow leaves after a few days due to the damaged root system. Once it return to normal, the leave yellowing will stop .

Never miss a care task again!

What's the best method to water my Crepe myrtle?

You might want to put a garden hose at the plant base to ensure that you're promoting excellent root development. Avoid directly spraying the leaves, and know that the leaves will require more watering if they are outdoors and facing direct sunlight. You can also use bubblers that you can put on to each plant to moisten the roots. Also, use soaker hoses that can cover the entire garden or bed when adding or removing plants to push the roots deeply. Drain any excess water and wait for the soil to dry before watering. Water at ground level to prevent diseases. On a sunny day, you might want to spray the entire bush with water. Whether potted or in-ground, please remember Crepe myrtle prefers deep watering over light sprinkling.

Irrigation of the soil is also required if you have a garden. When you live in a hot climate, you might want to water once a week. Only water when you notice that about 2 to 3 inches of soil become too dry outdoors or indoors. Consider the amount of rainwater on the plant and ensure not to add to it to prevent root rot.You may not need additional watering of the plants if there is a lot of rainfall.Crepe myrtle generally grows during spring and fall. When they are outdoors, you need to add mulch about 3 to 4 inches deep to conserve more water.

You need to water the plants more frequently in sandy soil because this type tends to drain faster. However, with the clay one, you need to water this less frequently where you could go for 2-3 days to dry the plant and not develop any root rot. You could mark the date on the calendar whenever you water and when you notice that the leaves are starting to droop. This can mean that you might be a day late.

How much water do I need to give my Crepe myrtle?

The Crepe myrtle generally needs about a gallon of water each schedule,With the potted plants, you might want to water them deeply until you see that the water is dripping at the bottom of the pot. Then, wait for the soil to dry before watering them again. You can use a water calculator or a moisture meter to determine the amount you've given to your plant in a week. Provide plenty of water, especially in the flowering period, but let the moisture evaporate afterwards to prevent root rot.

If Crepe myrtle is planted outdoor with adequate rainfall, it may not need additional watering. When Crepe myrtle is young or newly planted, make sure it gets 1-2 inches of rain per week.

Should I adjust the watering frequency for my Crepe myrtle according to different seasons or climates?

The Crepe myrtle needs outdoors come from rain, with only persistent dry weather requiring watering. Throughout the spring and fall growing seasons, the soil needs to be kept moist but not soggy, and alternating dry and moist soil conditions will allow the Crepe myrtle to grow well. Throughout the summer, hot weather can cause water to evaporate too quickly, and if there is a lack of rainfall, you will need to water more frequently and extra to keep it moist.

Usually, the Crepe myrtle will need less water during the winter. Since the Crepe myrtle will drop their leaves and go dormant, you can put them into a well-draining but moisture-retentive soil mixture like the terracotta to help the water evaporate quicker. Once your Crepe myrtle growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Crepe myrtle can rely on the fall and winter rains to survive the entire dormant period.

After the spring, you can cultivate your Crepe myrtle and encourage it to grow and bloom when the temperature becomes warmer.This plant is not generally a fan of ponding or drought when flowering. You must ensure that the drainage is good at all times, especially during the winter.

When the plant is in a pot, the plant has limited root growth. Keep them well-watered, especially if they are planted in pots during summer. They don't like cold and wet roots, so provide adequate drainage, especially if they are still growing.

It's always best to water your Crepe myrtle’s diligently. Get the entire root system into a deep soak at least once or twice a week, depending on the weather. It's best to avoid shallow sprinkles that reach the leaves since they generally encourage the growth of fungi and don't reach deep into the roots. Don't allow the Crepe myrtle’s to dry out completely in the fall or winter, even if they are already dormancy.

Don't drown the plants because they generally don't like sitting in water for too long. They can die during winter if the soil does not drain well. Also, apply mulch whenever possible to reduce stress, conserve water, and encourage healthy blooms.

What should I be careful with when I water my Crepe myrtle in different seasons, climates, or during different growing periods?

If planting in the ground, Crepe myrtle mostly relies on rain. However, if there is no rainfall for 2-3 weeks, you may need to give proper consideration to giving the plants a deep watering. If watering Crepe myrtle in summer, you should try to do it in the morning. A large temperature difference between the water temperature and the root system can stress the roots. You need to avoid watering the bushes when it's too hot outside. Start mulching them during the spring when the ground is not too cold.

The age of the plants matter. Lack of water is one of the most common reasons the newly planted ones fail to grow. After they are established, you need to ease off the watering schedule.

Reduce watering them during the fall and winter, especially if they have a water-retaining material in the soil. The dry winds in winter can dry them out, and the newly planted ones can be at risk of drought during windy winter, summer, and fall. Windy seasons mean that there's more watering required. The ones planted in the pot tend to dry out faster, so they need more watering. Once you see that they bloom less, the leaves begin to dry up.

Potted plants are relatively complex to water and fluctuate in frequency. Always be careful that the pot-planted plant don't sit in the water. Avoid putting them in containers with saucers, bowls, and trays. Too much watering in the fall can make the foliage look mottled or yellowish. It's always a good idea to prevent overwatering them regardless of the current climate or season that you might have. During the months when Crepe myrtle begins to flower, you might want to increase the watering frequency but give it a rest once they are fully grown.

Give them an adequate amount of water once every 3 to 5 days but don't give them regular schedules. Make sure the soil is dry by sticking your finger in the pot, or use a moisture meter if you're unsure if it's the right time. Too much root rot can cause them to die, so be careful not to overwater or underwater regardless of the climate or season you have in your area.

Why is watering my Crepe myrtle important?

Watering the Crepe myrtle helps transport the needed nutrients from the soil to the rest of the plant. The moisture will keep this species healthy if you know how much water to give. The watering requirements will depend on the weather in your area and the plant's soil.

The Crepe myrtle thrives on moist soil, but they can't generally tolerate waterlogging. Ensure to provide enough mulch when planted on the ground and never fall into the trap of watering too little. They enjoy a full can of watering where the water should be moist at the base when they are planted in a pot to get the best blooms.

If they are grown as foliage, you need to water them up to a depth of 10 to 20 inches so they will continue to grow. If it's raining, refrain from watering and let them get the nutrients they need from the rainwater.

Fertilizer

The slow-release organic fertilizers containing sulfur or iron are beneficial to the growth of crepe myrtle . As for newly planted crepe myrtle , one teaspoon of slow-release organic fertilizer should be applied once a month in the first year. In the two weeks before the frost, fertilization should be stopped to prevent frost from causing frost damage to the young branches after fertilization. After the root systems are formed, the crepe myrtle can be fertilized once a year in spring. 1/2 pound of fertilizer per 100 square ft should be applied based on the crown area. The fertilizer should be evenly spread on the ground, and then watered. It is not necessary to remove the mulch for fertilization. Excessive fertilization can result in overgrowth of leaves, less flowering and even diseases of crepe myrtle .

Its profusion of large, showy flowerheads makes Crepe myrtle a favorite with gardeners. Whether it’s growing in a container or as a flowering garden shrub/tree, it’s impossible to miss Crepe myrtle when it’s blooming in the summer. However, it also requires the right fertilizer at the correct time to support the large blooms and encourage healthy growth.

You need to fertilize a Crepe myrtle for a few important reasons. The most obvious of these reasons is that fertilizer will help your Crepe myrtle produce lovely blooms. Fertilizing in early spring is one of the best ways to ensure that your Crepe myrtle has excellent flowers during that season. Fertilizer also gives your Crepe myrtle plenty of energy that it can store in the ground during its dormant growth phases. Giving your Crepe myrtle some extra nutrients during the fall planting process or during the late spring will help your Crepe myrtle hold more energy to use once active growth resumes.

Timing is crucial when it comes to fertilizing Crepe myrtle. If you use fertilizer too early while the Crepe myrtle is still dormant at this time. This fertilizer cannot be used effectively and will be washed away by rainwater, causing waste and pollution. The first application of fertilizer should be applied in the early spring. Continue fertilizing once a month until early summer.

The ideal fertilizer for a Crepe myrtle is one that has a relatively balanced mix of the three main plant nutrients, with slightly higher amounts of phosphorus. Alternatively, some gardeners choose to improve their Crepe myrtle 's soil by adding organic materials such as compost, worm castings, and manure. Some experienced gardeners will supplement 1-2 times with water-soluble fertilizers containing phosphorus when the flower buds start to appear. This will help the flowers develop better and allow them to grow larger and bloom longer. Fertilizers can come in many forms, and most of these forms will work well for your Crepe myrtle. However, some of the best fertilizers for Crepe myrtle come in either a liquid or a powdered form. Regardless of which you use, you should ensure that you dilute your fertilizer and apply it while watering your Crepe myrtle.

Always follow directions for the specific type of fertilizer and do research on how to use it for the Crepe myrtle you are growing. It is important not to over-fertilize your Crepe myrtle, so determining the correct amount to use is crucial. The usual rule of thumb is to use the age of the tree (if known) or the diameter of the trunk to understand how much fertilizer should be used. Estimate a one-tenth of a pound of fertilizer per year or per inch of trunk, with a maximum of one pound. Granular fertilizers and organic fertilizers such as blood meal are applied by sprinkling the substance around the base of the tree all the way to the drip line (the space below the farthest-reaching branches) but do not let fertilizer come in contact with the trunk. Over time, the granules break down and filter into the soil to be absorbed into the roots. After fertilizing, spread an inch-deep layer of compost around the base of the tree and water thoroughly.

It is far better to under-fertilize than over-fertilize, since you can always add more but you cannot easily take away excess fertilizer. Over-fertilizing your Crepe myrtle may cause brown leaf tips and edges, yellowing, wilting leaves, and possibly a visible crust of fertilizer salts on the surface of the soil around the tree. This condition is called fertilizer burn and results from too many accumulated salts in the plant’s cells. If excess nitrogen is the issue, the Crepe myrtle will produce a lot of leaves but won’t grow much flowers since nitrogen supports foliage growth. If you have overfertilized, you could try removing the top layer of soil under the Crepe myrtle to remove the most concentrated area of fertilizer. Then flush the area by watering heavily to try to get rid of fertilizer around the roots.

Avoid giving Crepe myrtle a fertilizer with too much nitrogen, since this can lead to development of plenty of leaves but not many blooms. Look for fertilizer with a lower level of nitrogen compared to other nutrients. Do not fertilize after the early autumn, which can cause too much growth just before winter. Also, Crepe myrtle should not be fertilized during hot and dry times of year, since dry soil does not deliver fertilizer as effectively as moist soil. Fertilizing at this time can also stimulate growth which in turn needs more water that may not be available. It is best to keep fertilizer for earlier in the season when temperatures are cooler. Finally, remember that Crepe myrtle can absorb fertilizer that has been applied to nearby plants or lawns, so be cautious about inadvertently giving tree/shurb a double-dose of fertilizer.

Sunlight

The crepe myrtle like full sunlight and are slightly shade-tolerant. They require plenty of light to grow vigorously and bloom in large numbers. Please select a field with 6-8h of direct sunlight a day, such as an open space in a garden, and avoid the shade from tall fences, buildings and other trees. Excessive shading will not only lead to the crepe myrtle not exuberant and less flowers, but also cause some diseases and pests on the leaves and buds, such as powdery mildew and sooty blotch.

How much/long should Crepe myrtle get sunlight per day for healthy growth?

For healthy growth, make sure that Crepe myrtle receives at least 3–6 hours of sun each day. This is actually a minimum requirement—most plants that can handle part sun can also thrive in full sun, but because they require less light for photosynthesis, they are more flexible than plants that require full sun or part shade.

Free

What type of sunlight does Crepe myrtle need?

Crepe myrtle does best with exposure to full or part sun. They will perform best with direct morning light, but in summer they need protection from the strong afternoon sun. In temperate environments, too much hot afternoon sun can burn the leaves, damaging the plant's appearance and health.

Can sunlight damage Crepe myrtle? How to protect Crepe myrtle from the sun and heat damage?

Crepe myrtle planted indoors can easily be damaged by direct sunlight when it's moved outdoors. The best way to prevent sunburns from overexposure is to move pots gradually from a shaded area to a brighter spot, gradually. But even plants that are acclimated to the summer sun can be damaged by extreme heat. In a heatwave, it is important to keep the soil consistently moist so that plants can cope with excessive levels of heat. Moving plants in containers to areas with afternoon shade or erecting a shade cloth over them can protect sensitive Crepe myrtle during extreme weather events.

Does Crepe myrtle need to avoid sun exposure? / Should I protect Crepe myrtle from the sun?

While bright morning sun and some full sun exposure can be highly beneficial for Crepe myrtle, the harsh, hot midday sun of summer can be too much to handle.

If planted in the ground, the summer sun will usually ramp up slowly enough through the season for Crepe myrtle to gradually adapt to its intensity. But a potted plant that has been indoors or in a protected location will often suffer injury when placed suddenly into a location where the direct summer sun reaches it in the hottest part of the day.

To protect this plant from the brutal afternoon summer sun, plant or place it in an understory location where it is shaded at midday by taller trees and plants or by a building or landscape feature.

What will happen if Crepe myrtle gets inadequate sunlight?

When Crepe myrtle receives too little sun, they may become pale green or display drooping, yellow leaves. While some leaf drop is normal, if leaves are dropping but no new ones are growing in to replace them, it is a sign that something is wrong. If Crepe myrtle receiving inadequate light does manage to grow, the new growth is often spindly, pale, and prone to insect infestation. Paying attention to these signs and changing the lighting conditions of the plant will make a significant difference.

Does Crepe myrtle need special care about sunlight during its different growth stages?

Tender, new leaves are especially sensitive to sunburn. Bearing this in mind, very young Crepe myrtle and when it's in a strong growth phase, such as in late spring and early summer, will be more sensitive to harsh sun and heat than the mature one or those in a more dormant fall growth stage. Crepe myrtle fresh from a nursery is also usually not prepared for strong full sunlight and must be introduced to it slowly.

Are there any cautions or tips for sunlight and Crepe myrtle?

Recently transplanted Crepe myrtle will often experience a bit of shock and will need to be cared for carefully, either shaded from bright afternoon sun or placed in a protected area. On very hot days, you may see the leaves of Crepe myrtle drooping—this is usually nothing to worry about. Plants will send the water in their leaves down into their roots to protect them from burning. However, if the leaves are still drooping in the evening or the next morning, the plant needs water. Always avoid watering during the hottest times of day, as sunlight can hit wet leaves and scorch them easily.

Crepe myrtle that has been underwatered will be weaker than that with consistently moist soil. This can leave it with weak roots that are unable to protect the leaves on hot, sunny summer days by diverting water away from the leaves. Care for an underwatered plant by giving it a long, deep watering and then allowing the top two inches of soil to dry out before the next watering. Even if it loses its leaves, if cared for properly it will grow new ones.

Pruning

Crepe myrtle blossoms in summer, therefore, it requires large-scale pruning during the dormancy period from winter to early spring. Pruning should be avoided in early autumn, as it will force the crepe myrtle to grow rather than dormancy. Severe freezing damage in winter can cause plant death in case of incomplete dormancy.

For a lagerstroemia plant with single trunk, one main trunk should be reserved, all lateral branches within 1.5 to 2 m from the ground should be trimmed off, and 3 branches on the trunk should be preserved as the main branches. For a lagerstroemia plant with multiple trunks, 3-5 robust branches should be reserved as the main trunks, the sprouts should be removed firstly, and the lateral branches of the lower half should be then removed for a tree form. Finally, the crowded or crossed branches in the crown and the branches that are too thin and too long should be trimmed to ensure good ventilation and light conditions in the center of the crown. The picture below shows a lagerstroemia plant with single trunk.

In addition to the pruning for shaping, attention should also be paid to removing the withered and dead branches in every winter. The withered branches are generally weak and yellow or extremely dark brown. If it is uncertain whether a branch is dead or not, a small amount of bark can be peeled off to see if the inside of the branch is green. During the growing season, the sprouts in the lower part of the stem should be removed from time to time before flowering. New shoots that germinate in spring should not be pruned or truncated. After flowering in summer, the withered flowers (inflorescences) should be cut off in time to reduce the loss of nutrients and promote the germination of new branches and re-flowering. Excessive topping should be avoided. Excessive pruning weakens the tree, causing the plant to grow a large number of tiny new branches. Although the plant is small and shrubby, but dense branches and poor ventilation are easy to cause powdery mildew. In addition, over-pruned lagerstroemia plants will grow branches and leaves with a lot of nutrient, thus reducing flowering and affecting the ornamental effect. The picture below shows a lagerstroemia that has been over-pruned.

Does my Crepe myrtle need to be pruned?

While one could technically let the Crepe myrtle go without pruning, the form and health of the tree may suffer, and will end up looking quite shaggy and unorganized. Crepe myrtle is grown for its attractive flowers. While not strictly necessary, many people prefer to prune this plant every year or two to encourage flowering and to maintain an attractive appearance and keep your Crepe myrtle in great shape. Pruning not only helps the tree relieve itself of burdens like dead wood and disease, but it also gives you the creative ability to style the tree in a way that works for you!

When is the best time to prune my Crepe myrtle?

There are ultimately two times of the year that work best for pruning Crepe myrtle. Although it can be pruned at any time in cases of emergency, such as a broken branch, pruning should be left to the seasons where Crepe myrtle isn’t actively blooming or putting on new growth. This is a very typical pruning rule for most woody plants. Pruning can either take place just before the tree begins to put on new growth in very early Spring, or it can wait until just after all the blooms have fallen and your Crepe myrtle is starting to fall into dormancy. The best time to prune is just before new growth appears, but either time is great for removing extra growth. Use garden shears to cut off broken, dead, weak or diseased branches from Crepe myrtle. Observe the branch to see if it is dry and brittle. You can also tell if a dead branch is present by its color. If the branch is dark green, it is weak and dying; if the branch is brown, then the branch is already a dead branch. You can also choose to prune at both times in the same year if your Crepe myrtle needs a bit of an overhaul. To avoid taking off too much at one time, you can simply prune back before new growth, and then again once it’s had its time to bloom and pollinate. Of course, pruning does come with some mild risks, so it’s better to prune only once per year if you can. Finally, you may prefer to just trim off dead or damaged portions of the plant, including deadheading spent flowers, to keep it looking its best. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely. Blooms should be cut off just below the flower head.

How can I prune my Crepe myrtle?

To prune the Crepe myrtle, first identify how the tree has grown thus far. It can either look bushy, like a shrub, or it can have one or more trunks that stem up from the ground with foliage in the top quadrant. If you have a bushy Crepe myrtle and you like it that way, then you can simply trim just as you would an average shrub, by removing new growths at equal heights just above a leaf node. For taller Crepe myrtle, there’s a little more to it. Identify the look you want first. If all you’re looking for is a quick prune and done, then all you really need to do is cut back any growth that is growing towards the inside of the canopy, as well as any “suckers”, or stems that grow below the canopy line. In this case, it is necessary to prune in winter, giving priority to the reduction of dead and dry branches. Afterwards, the crossed and parallel branches are pruned off, which increases the space for other branches to grow. In this case, it is necessary to prune in winter, giving priority to the reduction of dead and dry branches. Afterwards, the crossed and parallel branches are pruned off, which will increase the space for other branches to grow. If what you need is to take off some serious area, then more planning is in line. Crepe myrtle branch out in a fan fashion from the center trunk, and each branch will have its own branches that grow from them, as well. Try to take off branches that are pointing downward at their bases, but avoid cutting too much away from each secondary branch. From here, you can do some milder pruning around the areas where you removed branches in order to clean up the look and blend in the newly trimmed sections. Never trim off so much that no secondary branches are left from the main trunk; Crepe myrtle can tolerate this, but it takes years for them to recover fully. These prunings need to be done in late winter or early spring. Pruning Crepe myrtle encourages flowering and provides Crepe myrtle with more ornamental value. Finally, you may prefer to just trim off dead or damaged portions of the plant, including deadheading spent flowers, to keep it looking its best. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely. Blooms should be cut off just below the flower head.

What should I do after pruning my Crepe myrtle?

You can take a few extra steps to make sure that your pruning is both successful and healthy. As with most woody, flowering trees, Crepe myrtle should be spoiled with a little extra water over the following week so that it has the means to heal its wounds. Crepe myrtle is a tough cookie, so it can take care of itself for the most part after the annual snipping. You can also fertilize just before or after pruning, which gives Crepe myrtle a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. If you have other plants or trees nearby that are affected by diseases such as fungi or pests, you can also apply honey to the wounds just after pruning to create a sort of natural bandage.

What techniques and tips should I use when pruning my Crepe myrtle?

Pruning the Crepe myrtle should be saved until the tree is mature, or has at least one thick stem or trunk that other, smaller branches grow from. That being said, you can train younger Crepe myrtle to grow in a style that you like by snipping off new growths at the base of the tree where it meets the ground. Here’s a general idea of how to get started pruning your Crepe myrtle. Tools For pruning, you’ll of course need some sort of clippers. Loppers are best for thicker branches, while hand pruners will usually get the job done on smaller branches that are less than the thickness of your average pencil. You’ll also need a good pair of gloves, as well as some sort of protective eyewear. Pruning can sometimes get a little pokey, so you want to make sure that none of the stray branches or debris end up in your eyes.

What are the common issues that I should be aware of when pruning my Crepe myrtle?

One of the most common issues with Crepe myrtle is overgrowth. Once they get unruly, it can be tricky to get them to look their best again. In some situations, it may be best to cut away everything except for secondary branches- those that grow from the main stem or trunk- and henceforth only trim back new branches liberally until your Crepe myrtle regains its shape.

Advanced Care Guide

Temperature

Crepe myrtle, native to Asia, is widely distributed in the temperate to subtropical zones. It grows well in the warm and humid climates. If planted in the cold region, it's prone to freeze to death in cold climates.

What is the optimal temperature for Crepe myrtle?

The best temperature for Crepe myrtle to thrive is 65~80℉(18~27℃). During the primary growing phase, the highest temperature tolerable would be 95℉(35℃), while the lowest tolerable temperature would be 15℉(-10℃). This species is tolerant of low temperatures and will survive freezing winters. The perfect, highest, and lowest temperature range:

Perfect：65~80℉(18~27℃)

Highest：85~95℉(30~35℃)

Lowest：-5~15℉(-20~-10℃) or below

Free

Should I adjust the temperature for Crepe myrtle during different growing phases?

Research shows that Crepe myrtle will begin to exhibit signs of stunted growth during prolonged periods of higher temperatures, especially during the development of axillary buds and the growth of main shoots. Keeping the temperatures consistent and cooler, around 65℉(18℃), will encourage vigorous growth after germination or transplanting.

How can I keep Crepe myrtle warm in cold seasons?

Crepe myrtle can withstand freezing temperatures when planted in the ground in areas that don’t get below of 15℉(-10℃) as an extreme temperature during the winter months. But if planted in pots or containers, then their roots must be protected from the winter cold. Do this by wrapping the container in a blanket or bringing it inside where it will be fully protected from the elements.

What damage will Crepe myrtle suffer if the temperature is too high/low?

Greater harm will come to Crepe myrtle if the temperature is consistently too high versus too low.

If Crepe myrtle gets too hot, seed germination and photosynthesis efficiency is lessened due to hormone triggers caused by heat stress. The plant will show signs through wilting, leaf browning, and potentially death.

If Crepe myrtle gets too cold, plant functions such as nutrient uptake and photosynthesis will cease, resulting in the possible death of the plant. If a single freezing event occurs during the growing season, then a membrane phase transition might occur, which can cause a cease in plant functions and death of the plant.

What tips and cautions should I keep in mind when it comes to temperature for Crepe myrtle?

Keeping the soil temperature consistent is one of the most important strategies to keeping Crepe myrtle healthy, which leads to successful budding, flowering, and new growth. Do this by consistently watering, adding mulch to bare soil, and planting in the shade.

How can I keep Crepe myrtle warm without a heat pad?

Due to the cold tolerance of Crepe myrtle, heating pads will not be necessary if planted outside in the ground. If the plant is in an outdoor pot, then bring it inside a heated house and place it in a sunny window during the winter months.

How can I provide Crepe myrtle with an adequate temperature condition?

To ensure adequate temperature conditions are present, plant Crepe myrtle in an area with partial shade. If possible, use afternoon shade to provide the best protection during the hottest part of the day. This will also result in lower temperatures in the soil due to increased moisture retention. If Crepe myrtle is planted indoors, then keep the container away from windows and out of direct sunlight during the summer months to prevent the soil temperature from spiking daily.

How can I save Crepe myrtle from temperature damage?

During the summer or times of high heat, give Crepe myrtle extra shade and water to help cool its leaves, roots, and soil. During cold snaps or growing season freezes, cover sensitive budding vegetation with frost cloth or water using sprinkler systems. If it’s only nearing freezing temperatures for a short period, then water during the day several hours before the freeze. If the temperature is predicted to remain below freezing for an extended period, then keep the sprinkler running until the temperature rises above freezing the following day.

Should I adjust the temperature for Crepe myrtle in different seasons?

Crepe myrtle is a mid-temperature plant that can easily tolerate the typical fluctuations of the seasons and remain a hardy species when planted in maintained landscapes areas, containers, or indoors. Therefore, adjusting the temperature during the different seasons is unnecessary for primary growth. If flowering is stunted or impeded, then allowing the plant to experience a season of winter freeze could help to revive flowering.

Under what conditions should I stop adjusting the temperature for Crepe myrtle?

If it becomes too difficult to lower the temperature for an indoor plant during the summer, then plant it outside in the ground or in a container. Make sure to plant Crepe myrtle in a shaded location and water often to keep the soil moist.

Soil

The crepe myrtle can tolerate different soil types and grow well in both calcareous and acid soil. The pH of most suitable soil for growth is 5.5-6.5. They like moist, fertile and well-drained sandy loam or loam. If the soil in the planting site is poor, it can be improved with compost or ordinary commercial fertilizers. If the soil is more viscous or sandy in texture, it can be adjusted with peat and rotten manure. Alkaline soil will cause leaves to turn yellow, organic fertilizers or garden compost can reduce the soil's pH value, and a small amount of agricultural lime can increase the pH.

Propagation

Planting

The crepe myrtle of good varieties usually reproduce by cutting. Early summer is the best period for cutting; the branches that grow out in this year should be selected and each cutting shoot should contain 2-3 buds. Cut out a horizontal cut at 8 mm - 1 cm above the first bud in the upper part of the cutting shoot; cut out a slanted cut at 5 mm - 8 mm to the last bud at the end of the cutting shoot; reserve the upper one pair of leaves, and subtract half of the remaining leaves to reduce transpiration and prevent the cutting shoot from losing water.

The cutting medium can be mixed peat and perlite (volume ratio: 2:1), and the river sand can be used alone. Soak the medium in 0.3% potassium permanganate solution for 0.5h-1.0h, rinse it with clean water, and air-dry it outside for one day for standby. The base of the cutting shoot should be soaked in 500mg/L indolebutyric acid (IBA) or naphthaleneacetic acid (NAA) solution for 10s, and the insertion depth should be half the length of the cutting shoot. Place the cutting shoots in a well-drained rooting medium in a cool area, seal them in a transparent plastic bag, and spray regularly to keep them moist. Cutting shoots take root after one week and the number of sprays should be reduced after rooting to prevent the roots from rotting. When the cutting shoots grow elastic root masses, they can be planted in the field or in a nutrient bowl.

Crepe myrtle provides good landscaping for your garden all year round, which is quite essential for the garden. As your Crepe myrtle grows, you may want to know how to get more of them for free. Or maybe your Crepe myrtle has been damaged by a pest or disease and you’d like to save it and propagate a new plant. This article is about how to propagate your Crepe myrtle. For a simpler procedure, hardwood cuttings is a good choice. Crepe myrtle can be propagated during the dormant season from mid-autumn until late winter. Most people prefer to take cuttings right after leaves drop, but it can be done successfully at other times, provided you avoid taking cuttings during severely cold periods. The beginning and ending of the dormant season are the most likely to be successful.Flash cuttings cannot tolerate the cold environment. If the winter temperatures in your area are low (e.g., below 0 ℉ for an extended period of time), it is recommended that you place the cuttings in a garage or outdoor incubator after cutting. This will help the cuttings to develop roots. When propagating Crepe myrtle, be sure your cutting tool is large enough and sharp enough to cut cleanly through the shoots. Using a dull tool can crush or tear the plant, which can lead to infection and disease.

Sharp garden pruners
Diluted bleach solution or isopropyl alcohol to clean tools
Rooting hormone (optional but recommended)
Deep container(s) with drainage holes for planting
Well-draining planting medium such as pine bark, perlite, or a potting soil mix

Steps: Step 1: Choose healthy shoots that are about as thick as a pencil for your propagation and 6 to 8 inches long, preferably from the previous year’s growth. Once you have identified your cuttings, use disinfected garden pruners to cut off the bud tip and take the remaining branch of the front section about 7-8 inches. If you are not putting them into containers immediately, keep the cuttings moist until you are able to pot them. TIP: Pay attention to which side is up when you are taking cuttings - it can be difficult to tell when there are no leaves Step 2: Prepare your containers by filling them with the planting medium. Adding compost to the soil can facilitate plant rooting. Step 3: Dip the bottom of your Crepe myrtle into rooting hormone, then insert one-third to two-thirds of the cutting into the substrate. Plant them about 2 inches apart. You should be able to plant as many as 10 to 12, depending on your container size. Step 4: Water thoroughly, making sure the potting medium is evenly moist but allowing it to drain. Step 5: Place the containers in a cold, protected location that receives some sunlight. An unheated garage, a porch, or a cold frame work well for this. Leave the Crepe myrtle there throughout the winter. Water occasionally to make sure the soil doesn’t dry out completely, although it can be dryer during the coldest winter months. Start watering more often as days get warmer in the spring. It is recommended that you place the cuttings in a garage or outdoor incubator after cutting if the winter temperatures in your area are low. Step 6: Move the containers outside to a spot that gets partial sun after the last frost. You can expect to see new leaves on your Crepe myrtle around the middle of spring. It’s important to be patient with this process because it is quite slow. In fact, it can take a year or longer for Crepe myrtle to be ready to be transplanted. Luckily there isn’t much maintenance during this time, and the process has a high likelihood of success. Even if your Crepe myrtle is putting out new growth, they may not be ready to be planted into the ground just yet. It is more important that there are plenty of healthy roots growing. The roots should be at least 3 inches long, but many people like to wait until roots start to grow out of the drainage holes to be sure that there is a proper root system. Mound or stool laying is also a common method of propagation, but it’s more complex. Begin the mound or stool layering process in the autumn by cutting back your plant; this will allow the plant to put its energy into growing new roots in the spring. When growth begins in the spring, it's time to start layering dirt over the new growth. Wait one or two months for the roots to sufficiently develop before dividing or propagating the new plants. Mound or stool layering takes time and patience, but the tools you need to accomplish it are minimal. So long as you have your handy shears and trowel, you can get started right away!

Sharp, sanitized scissors or shears
Trowel for covering the plant
Growing medium to cover the plant

Steps: Step 1: Cut the plant back to 4-6 inches from the ground during the dormant season. Or use scissors to circumferentially peel the lower part of the branch at 4-6 inches from the ground. Step 2: As new growth appears above the ground, layer soil over the new growth. Compacted with soil, this will allow the buried new growth shoots to root. Step 3: Make sure the regular growth of the mother plant during the pressing period, especially to keep properly moist to the area where the soil is mounded. Step 4: Dig up the mound of soil after 3-4 months then check the rooting situation. If vigorous roots have grown, cut off the roots along with the branches and plant them as new plants.

Planting in autumn or early spring is recommended, because a good root system can develop before the vigorous growing period if it’s planted before the germination of the plant. For seedling transplanting, the seedlings, 1-year to 3-year old, can be transplanted with naked roots. The seedlings, more than 3-year old, need to be planted with soil balls to keep the root system intact. The plant row spacing should be determined according to the variety, and sufficient space should be reserved to ensure good ventilation and reduce diseases. this information can usually be found on the label of the plant, for example, if this variety is 91 cm in width at maturity, and then separate the plants by about 91 cm. Fully loosen soil before planting, dig a pit with a diameter of 2-3 times of the plant, with a depth of approximately same as that of the nursery pot, backfill the soil, and the top of the root mass should be level with the ground or slightly above the ground to ensure sufficient oxygen for the root system.

Potting Suggestions

Should be repotted every 2-3 years in a large pot (2-3 times the size of the rootball), with good drainage holes.

Seasonal Care Tips

Seasonal Precautions

Better flowering performance can be achieved by fertilizing once a year in spring and watering 1-2 times a week during hot and dry summer. Before frost, pruning, fertilization and excessive watering should be stopped to ensure that the plants enter the dormancy period smoothly. After the leaves fall in autumn, pine needles, wheat straws, and fallen leaves should be covered around the roots. Winter is the best time to trim.

Some cold protection measures in winter can be carried out in relatively cold areas: For the low lagerstroemia plants, they can be pressed to the southeast direction or covered with soil with the covering thickness of 10 cm - 15 cm, and covered with mulch or straw shade. Remove the mulch at the beginning of the next spring and water the plants in time. For tall lagerstroemia plants, cover 30 cm - 50 cm thick soil around the root collar in early winter, warp the trunk with non-woven fabric or straw rope, remove the covering soil in early spring next year, and then remove the wrapping in mid-spring. For aboveground plants that are frozen to death in winter, the plants can be pruned to 20 cm above the ground in early spring. Then, wait for them to grow new branches.

Winter

Temperate flowering trees, vines, and shrubs like this plant require more care in the summer.

1

Frequent watering in the summer is a must in most climates, especially in the south. Check the soil’s moisture levels daily, watering when it is beginning to dry out.

2

Stop fertilizing in the summer while the plant is not in bloom.

3

summer is the ideal time to remove any spent blooms to encourage re-flowering in the fall.

4

Move container plants out of the bright sunlight.

5

Keep an eye out for pests and diseases. Removing plant debris from the area can help with any potential issues.

Your plant needs a bit of care in the autumn months to keep it looking its best and prepare it for winter.

1

In the late fall, you can give your plant a good prune. Remove any low-hanging or overcrowding branches, along with energy-sapping suckers, to keep the plant growing strong throughout the season.

2

Clean up any fallen leaves around the plant, as these leaves can cause harmful bacteria to grow around the plant.

3

Provide it with enough water to keep the soil moist, watering whenever the soil becomes dry.

4

Make sure it's exposed to strong sunlight and has some shade in the afternoon.

5

Watch out for any pests and diseases, such as mildew that looks like a powdery coating on the plant.

This plant requires some careful care during the winter.

1

It's important for your plant to be exposed to cold winter weather during this season, which will help boost its production in the spring, in a process sometimes called “chilling” your plant. Therefore, don't worry about keeping these plants warm or bringing them inside.

2

You may want to take this dormant time to prune away overcrowding, dead, or diseased parts, however.

Common Pests & Diseases

Common issues for Crepe myrtle based on 10 million real cases

Brown spot

This infection can cause brown spots or patches to appear on the plant.

Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Flower withering

Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.

Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.

Leaf rot

This pathogen can cause the leaves to rot.

Solutions: Bacterial infections need to be treated quickly to prevent the spread to neighboring, healthy plants, potentially wiping out large sections of your indoor or outdoor garden. In mild cases: Use sterilized (10% bleach solution) pruning shears or scissors to remove any infected plant parts, making sure to dispose of them off site. Use a copper-based bactericide to treat the unaffected foliage, as well as the soil, and neighboring plants. Follow the manufacturer’s rate and timing directions found on the product label. In severe cases, where more than half the leaves are affected: Remove all of the infected plants from the garden, disposing of them off site. Treat the soil and neighboring plants using a copper-based bactericide. Follow the manufacturer’s rate and timing directions found on the product label.

Powdery Mildew

Powdery mildew is a white mold that appears on leaves. It can be wiped away.

Solutions: As powdery Mildew spores are transported by the wind, it can be tricky to put a complete stop to the spread of the fungus. Luckily, there are several easy treatments for plants that are exhibiting symptoms: If powdery Mildew seems to be impacting isolated leaves or stems, they can simply be trimmed away and disposed of. Disinfect pruning tools after doing this. Remove any plant debris from the ground around the infected plants and dispose of it in the garbage. Then, cover the soil with a thick layer of mulch to limit reinfection. Milk sprays have been found to be useful in controlling powdery Mildew. Make up a spray consisting of 60% water and 40% milk and spray on the affected plants. This can also be used as a preventative measure. In cases where powdery Mildew is more widespread, plants can be sprayed with a mild sulfur- or copper-based fungicide or a non-toxic solution made from baking soda and soap. Sprays can help areas that have been recently infected, though they are less effective against well-established infections. If possible, try transplanting the plants to a sunnier location. Though powdery Mildew does fine in hot, dry conditions, it is unable to reproduce without some humidity. Putting plants in more direct sunlight can help stop the spread of the fungus. Trimming around closely-packed plants can help improve airflow, which also prevents the reproduction of the fungus.

Leaf deformity

Leaf deformities can have a variety of causes.

Solutions: Follow these steps to revive plants with abnormal leaves. Remove damaged leaves: Plants can recover from damage when given the time to do so. Remove any deformed leaves so they don't continue drawing energy from the plant. This also creates room for healthier ones to grow. Stop using herbicide: Though herbicide damage is challenging to diagnose, gardeners can potentially prevent deformed leaves by not using any and by strictly following manufacturers instructions. Spray insecticide: Prevent pests from inhabiting plant leaves by spraying with insecticide regularly and practicing good natural pest prevention techniques. Apply a balanced fertilizer: Solve nutrient deficiencies and excesses by using a well-balanced fertilizer (organic or conventional both work) before planting, and consider topdressing when signs of stress are apparent. Fix watering schedule: If plant leaves are curled downward due to too much or too little water, adjust the watering schedule so the soil is moist, but not damp. Remove infected plants: If the plant has succumbed to a viral infection, not much can be done to revive it. Remove and destroy all compromised plant material to prevent spread to other plants.

Underwatering

A lack of water will cause the leaves to gradually turn yellow starting at the base of the branch while the entire plant appears to wilt.

Solutions: Your plant is very thirsty and needs water promptly. You can revive your plant by giving it water. The easiest technique is to slowly pour water into your plant’s soil so that the whole surface is moistened. If you pour the water too quickly, the water will flow directly through rather than diffusing throughout the soil. If your plant’s pot does not have drainage holes, do not give your plant more than about a third of the pot’s volume of water. If your plant’s pot does have drainage holes, you can add water slowly until the soil is thoroughly moistened and the water flows freely through the pot. If you trim off yellow leaves to improve the plant’s appearance, do not remove more than a third of the plant’s leaves. It may be better to wait until leaves have died and fallen off to remove them.

Name story

Indian crape myrtle||Crape myrtle

The crepe myrtle has existed in plant history for more than a thousand years. Before it blossoms, people often think that its bright green leaves resemble another plant called Myrtle, surprised to see beautiful lush flowers later appearing. What makes it special is that, in full bloom, its flower petals are slightly wrinkly and exhibit a rich texture, like a crape. Since the beauty of the plant was discovered by Westerners in India, the plant was then referred to as the Indian crepe myrtle, or crepe myrtle for short.

Usages

Environmental Protection Value

Feeds a number of different bird species in the summer and winter, while also providing shelter and nesting areas.

Garden Use

Crepe myrtle is a deciduous shrub and tree that is commonly found in gardens within warmer climates. It is prized for its attractive winter bark, colorful fall foliage, and showy summer blooms. Its dense root system makes it suitable for erosion control. It is also used for boundaries. Crepe myrtle is good for Pollinator gardens. Plant with Peruvian Lily for color contrast.

Common Problems

Why cannot my crepe myrtle blossom?

The newly planted crepe myrtle may not blossom until the second year, so if your crepe myrtle is just planted this year, please wait patiently. The older crepe myrtle with overcrowded branches will be lack of sunlight which will also lead to less flowering. Please trim the plants properly in winter to ensure good ventilation and light conditions. Excessive pruning of crepe myrtle also causes the plants to use nutrients to grow branches and leaves, thus reducing the amount of flowers. It may be due to insufficient soil fertility if the plant has been properly pruned and well-lit but still does not blossom.

Why does not my lagerstroemia plant grow leaves?

Lagerstroemia plants are late-growing plants in spring, so it is very likely that the time has not come. If there are no leaves in the middle of spring, please check the branches for tiny leaf buds. Leaves will grow out if there are full and healthy leaf buds on the branches. In addition, please confirm whether the variety you selected is suitable for the climate. If it is too cold in winter, the leaf buds will be damaged, and they cannot grow into leaves. If the leaf buds have been frozen to death, please check whether the branches are healthy, observe whether the bark is green, if the branches have died, please remove them in time. Drought and soil hardening will also lead to no leaves. Please water them in the dry season in a timely manner and ensure loose soil and good drainage. In addition, timely removal of sprouts and weeds can also ensure sufficient nutrients for the lagerstroemia plants.

Are the roots of crepe myrtle invasive?

The roots of crepe myrtle may be scattered and long, but they are relatively weak and non-aggressive and do not produce many lateral roots, so they do not damage sidewalks, driveways or foundations. Crepe myrtle with shallow roots compete with weeds for moisture.

Are crepe myrtle poisonous?

According to data from the University of California, Davis, crepe myrtle are safe plants. ASPCA also lists them as plants non-toxic to dogs, cats and horses.
