What's the best method to water my Persian silk tree?

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 Persian silk tree prefers deep watering over light sprinkling.

What should I do if I water Persian silk tree too much/too little?

An overwatered Persian silk tree 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.

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 Persian silk tree 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 .

Always check the moisture levels at the pot when you have the Persian silk tree 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.

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 Persian silk tree 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.

How often should I water my Persian silk tree?

The Persian silk tree 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.

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.Persian silk tree 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 Persian silk tree?

The Persian silk tree 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 Persian silk tree is planted outdoor with adequate rainfall, it may not need additional watering. When Persian silk tree is young or newly planted, make sure it gets 1-2 inches of rain per week. As Persian silk tree 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 Persian silk tree 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.

Should I adjust the watering frequency for my Persian silk tree according to different seasons or climates?

The Persian silk tree 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 Persian silk tree 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 Persian silk tree will need less water during the winter. Since the Persian silk tree 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 Persian silk tree growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Persian silk tree can rely on the fall and winter rains to survive the entire dormant period.

After the spring, you can cultivate your Persian silk tree 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 Persian silk tree’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 Persian silk tree’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 Persian silk tree in different seasons, climates, or during different growing periods?

If planting in the ground, Persian silk tree 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 Persian silk tree 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 Persian silk tree 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 Persian silk tree important?

Watering the Persian silk tree 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 Persian silk tree 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.

Is pruning necessary for my Persian silk tree?

Despite having a relatively fast habit of growth, Persian silk tree does not require very much pruning. It is not necessary to routinely prune this tree, however, it does require some pruning every once in a while. Pruning can be done to tidy this tree up and remove any diseased or damaged foliage. Or Persian silk tree can be pruned for shaping.

When is the best time to prune my Persian silk tree?

Persian silk tree should be pruned as needed. Typically, these trees should be pruned to remove any damaged, yellowing, dying, or dead foliage. It is also necessary to prune this plant to remove any shoots that are congested or are crossing. The best time to prune Persian silk tree is between late winter to early spring. This is the period when pruning causes the least damage to the plant.

How can I prune my Persian silk tree?

Pruning Persian silk tree is a fairly easy task if you know what to look for. To prune these trees, you will need a pair of sharp pruning shears. Using your pruning shears, remove any damaged or diseased parts of the tree. Keep an eye out for any shoots that are becoming congested or are beginning to cross and remove them. Ideally, you should steer clear from pruning any of the tree’s lower limbs. Leaving these intact will allow the tree to have a more natural and open form. Additionally, leaving the lower limbs alone will help to prevent any disease-inducing stress, as well as suckers from forming.

What should I do after pruning my Persian silk tree?

There are no special requirements to follow after you have pruned your Persian silk tree. It is recommended, however, that you dispose of any diseased foliage that has been removed from the tree away from any other plants. This is to avoid spreading the disease to other plants. After pruning your Persian silk tree, you may apply a fertilizer treatment to encourage faster growth. Do not water the plants immediately after pruning as this can lead to fungal infestation of the plants through the wounds.

What should I be careful with when pruning my Persian silk tree during different growing stages?

The best time to prune Persian silk tree is between late winter to early spring. This is the period when pruning causes the least damage to the plant. Keep an eye out for any shoots that are becoming congested or are beginning to cross and remove them. Ideally, you should steer clear from pruning any of the tree’s lower limbs. Leaving these intact will allow the tree to have a more natural and open form. This will increase ventilation and light, reduce disease infection and allow Persian silk tree to grow more vigorously. When pruning branches you need to leave the strong ones and remove the weak ones, keeping healthy auxiliary branches that grow outwards at about 45 degrees. Branches that are too angled or too small should be removed. Pruning Saw is required if the branch is more than three quarters of an inch in size, pruning should be done in the direction of the "Branch bark ridge" to the "Branch collar" to allow for good healing. Branches that require a saw need to be pruned using the "three-cut method", which prevents the bark of the branch from tearing and creating cracks in the trunk, which can be detrimental to the recovery of the plant. Finally, you may prefer to just trim off dead or damaged portions of the plant to keep it looking its best as if it's possible. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely.

Are there any tips for pruning my Persian silk tree?

The best thing to remember about Persian silk tree is that they do not require routine pruning. Your tree will likely grow better if you prune it as and when it is necessary and no more than that. Additionally, you should also keep in mind that it is better to leave the lower limbs of this tree alone to prevent stress-induced diseases from attacking your tree. Different diameter branches require different pruning tools. If the tree is too tall, pruning needs to be done safely or by a professional.

How much/long should Persian silk tree get sunlight per day for healthy growth?

For healthy growth, make sure that Persian silk tree 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.

What type of sunlight does Persian silk tree need?

Persian silk tree 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 Persian silk tree? How to protect Persian silk tree from the sun and heat damage?

Persian silk tree 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 Persian silk tree during extreme weather events.

Does Persian silk tree need to avoid sun exposure? / Should I protect Persian silk tree from the sun?

While bright morning sun and some full sun exposure can be highly beneficial for Persian silk tree, 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 Persian silk tree 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 Persian silk tree gets inadequate sunlight?

When Persian silk tree 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 Persian silk tree 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 Persian silk tree need special care about sunlight during its different growth stages?

Tender, new leaves are especially sensitive to sunburn. Bearing this in mind, very young Persian silk tree 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. Persian silk tree 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 Persian silk tree?

Recently transplanted Persian silk tree 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 Persian silk tree 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.

Persian silk tree 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.

What is the optimal temperature for Persian silk tree?

The best temperature for Persian silk tree 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

Should I adjust the temperature for Persian silk tree during different growing phases?

Research shows that Persian silk tree 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 Persian silk tree warm in cold seasons?

Persian silk tree 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 Persian silk tree suffer if the temperature is too high/low?

Greater harm will come to Persian silk tree if the temperature is consistently too high versus too low.

If Persian silk tree 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 Persian silk tree 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 Persian silk tree?

Keeping the soil temperature consistent is one of the most important strategies to keeping Persian silk tree 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 Persian silk tree warm without a heat pad?

Due to the cold tolerance of Persian silk tree, 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 Persian silk tree with an adequate temperature condition?

To ensure adequate temperature conditions are present, plant Persian silk tree 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 Persian silk tree 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 Persian silk tree from temperature damage?

During the summer or times of high heat, give Persian silk tree 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 Persian silk tree in different seasons?

Persian silk tree 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 Persian silk tree?

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 Persian silk tree in a shaded location and water often to keep the soil moist.

Why do I need to fertilize my Persian silk tree?

You need to fertilize a Persian silk tree for a few important reasons. The most obvious of these reasons is that fertilizer will help your Persian silk tree produce lovely blooms. Fertilizing in early spring is one of the best ways to ensure that your Persian silk tree has excellent flowers during that season.

Fertilizer also gives your Persian silk tree plenty of energy that it can store in the ground during its dormant growth phases. Giving your Persian silk tree some extra nutrients during the fall planting process or during the late spring will help your Persian silk tree hold more energy to use once active growth resumes.

When is the best time to fertilize my Persian silk tree?

Timing is crucial when it comes to fertilizing Persian silk tree. If you use fertilizer too early while the Persian silk tree 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.

When should I avoid fertilizing my Persian silk tree?

Avoid giving Persian silk tree 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, Persian silk tree 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 Persian silk tree 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.

What type of fertilizer does my Persian silk tree need?

The ideal fertilizer for a Persian silk tree 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 Persian silk tree '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 Persian silk tree. However, some of the best fertilizers for Persian silk tree 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 Persian silk tree.

How do I fertilize my Persian silk tree?

Always follow directions for the specific type of fertilizer and do research on how to use it for the Persian silk tree you are growing. It is important not to over-fertilize your Persian silk tree, 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.

What happens if I fertilize my Persian silk tree too much?

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 Persian silk tree 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 Persian silk tree 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 Persian silk tree 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.

Feng shui direction

East

The persian silk tree holds positive potential in Feng Shui practice due to its delicate, feathery blooms and elegant form. While it enhances visual appeal, its compatibility with East-facing directions results from its association with auspicious energies, particularly the nourishment and renewal amplified by sunrise. However, each individual's energies and preferences vary, making the persian silk tree's Feng Shui implications subjective and person-specific.

Water

Every 1-2 weeks

The persian silk tree prefers moderately moist soil conditions but can tolerate some dryness. This plant originates from environments with seasonal rainfall patterns. Water deeply and evenly, taking care to not overwater, as the persian silk tree does not enjoy soggy roots.

Lighting

Full sun

The persian silk tree thrives when exposed to a generous amount of daily sunlight, maximizing its growth and health. Still, it manages to tolerate conditions where sunlight is partially obscured. The light intensity is crucial for its different growth stages. Its origin habitat had plenty of sun exposure which it has adapted to. Too much or too little exposure can impact its wellness negatively.

Temperature

-10 to 35 ℃

The native growth environment for persian silk tree is warm and temperate regions with temperatures ranging from 10 to 35 ℃ (50 to 95 ℉). It prefers a warm and humid climate, but it can tolerate a wide range of temperatures. During the summer months, it can withstand heat up to 35 ℃ (95 ℉), but it needs protection from hot winds. In the winter, when the temperature drops below 10 ℃ (50 ℉), providing it with a protective covering is recommended.

Transplant spacing

20-35 feet

The best time to transplant persian silk tree is in early spring, just as new growth begins. This gives the plant ample time to settle and establish its root system. Choose a well-draining sunlit location. Remember to gently loosen the roots before planting for successful root establishment.

Pollination Difficulty

Normal

The vibrant persian silk tree seduces its primary pollinators - bees and moths, with an irresistible floral attractant. Using entomophily method, these insects play a crucial part in persian silk tree's pollination mechanism as they transfer pollen while foraging. This fascinating spectacle is most prevalent in the warm charm of daylight for optimal pollination activity!

Common Pests & Diseases

Common issues for Persian silk tree based on 10 million real cases

Fruit withering

Fungal infection or normal ripening can cause the fruit to dry out.

Solutions: There are a number of appropriate solutions to control fruit withering: Remove any fruit as soon as it shows any signs of infection. Do not compost. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.

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.

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.

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.

Aged yellow and dry

Natural aging can cause leaves to turn yellow and dry out.

Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.

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.

Weed Control

Weeds

Persian silk tree is commonly grown as an ornamental tree. Popular for its fluffy flowers which attract pollinators, it spreads very easily, and is considered an invasive plant in the United States.

How to Control it

Persian silk tree produces seeds that can remain viable for up to 5 years, and maintain a high germination rate of 90%. Because of this, planting it as an ornamental is not recommended, and the best solution to prevent its spread is to cut the tree down. New sprouts can reemerge from the cut tree, so it is advised to apply herbicides to the stump. Digging out the root is also recommended, because broken segments can continue to sprout. If you opt for herbicide use, consult an agricultural expert to find the best active substance for your geographic region. Spray on a windless day to avoid drift.
