Care Guide for Royal poinciana
Water
Flamboyant tree is drought-resistant, but it would appreciate frequent watering during the summer. The soil should dry out completely in between waterings. Overwatering can damage the roots. Give less water in the fall, and no water in the winter.
Fertilization
Giving fertilizer to the royal poinciana during the spring and summer will result in more vibrant blooms. Feed this plant a slow-release fertilizer alongside water twice a year, during the spring and fall; an organic, all-purpose fertilizer once a month; or a liquid fertilizer once a week. Discontinue feeding in the winter.
Pruning
Trim the diseased, withered leaves once a month.

Fertilizing What's the best method to water my Royal poinciana?
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 Royal poinciana prefers deep watering over light sprinkling.

What should I do if I water Royal poinciana too much/too little?
An overwatered Royal poinciana 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 Royal poinciana 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 Royal poinciana 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 Royal poinciana 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 Royal poinciana?
The Royal poinciana 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.Royal poinciana 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 Royal poinciana?
The Royal poinciana 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 Royal poinciana is planted outdoor with adequate rainfall, it may not need additional watering. When Royal poinciana is young or newly planted, make sure it gets 1-2 inches of rain per week. As Royal poinciana 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 Royal poinciana 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 Royal poinciana according to different seasons or climates?
The Royal poinciana 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 Royal poinciana 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 Royal poinciana will need less water during the winter. Since the Royal poinciana 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 Royal poinciana growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Royal poinciana can rely on the fall and winter rains to survive the entire dormant period.
After the spring, you can cultivate your Royal poinciana 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 Royal poinciana’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 Royal poinciana’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 Royal poinciana in different seasons, climates, or during different growing periods?
If planting in the ground, Royal poinciana 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 Royal poinciana 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 Royal poinciana 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 Royal poinciana important?
Watering the Royal poinciana 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 Royal poinciana 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.

Common Pests & Diseases
Common issues for Royal poinciana based on 10 million real cases
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
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.
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Solutions: The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms. Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves. Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement. Protect trees from severe root damage of nearby construction and excavation. If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach. If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry. Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections. If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.
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.
Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.

Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions
Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control.
Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees.
- Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree.
- Contact an arborist for best control practices regarding infected trees.
- To properly control longhorn beetles, all host plants in a given area must be treated.
- Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Prevention
- Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
- Check with local tree companies about which tree species have fewer problems.
- Avoid moving firewood as this can introduce exotic longhorn beetles.
- Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.

Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
- Both leaves and blossom on the tips of branches will go brown and wither.
- Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
- Any fruit that does appear will turn wrinkled and fail to develop.
- Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.
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.
Prevention
Preventative measures include:
- Ensuring adequate spacing between plants or trees.
- Staking plants that are prone to tumbling to prevent moisture or humidity build up.
- Prune correctly so that there is adequate air movement and remove any dead or diseased branches that may carry spores.
- Practice good plant hygiene by removing fallen material and destroying it as soon as possible.

Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
- Not enough water. A lack of water will lead to dry plant tissue.
- Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
- Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
- Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
- Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
- Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
- Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
- Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
- Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
- Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
- Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
- Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
- Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
- Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention involves providing your plant with the proper environment.
- Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
- Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
- Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
- Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Overview
Leaf scorch refers to two general conditions: physiological leaf scorch and bacterial leaf scorch. It causes leaves to discolor starting along the margins, and eventually die.
Leaf scorch development is most common in the hot, dry season, becoming most noticeable in late summer. However, it can occur at other times of the year. It most often affects young trees and shrubs, but it can also affect flowers, vegetables, and other plants.
Leaf scorch can get progressively worse over multiple seasons. If the root causes are not addressed, leaf scorch can lead to plant death.
While you cannot reverse the damage caused by physiological leaf scorch, you can prevent further damage. With proper management, plants will fully recover. However, there is no cure for bacterial leaf scorch, which is a systemic infection.
Symptom Analysis
- Yellow, brown, or blackened leaves starting with the leaf margins
- Dying twig tips on trees and shrubs as leaves die and fall
- Often there is a bright yellow border line between the dead and living leaf tissue
Disease Cause
There are numerous contributing causes of leaf scorch.
Bacterial leaf scorch is caused by the bacterium Xylella fastidiosa. The bacteria block the xylem vessels, preventing water movement. Symptoms may vary across species.
Physiological leaf scorch most commonly occurs when a plant cannot take up enough water. Numerous conditions can lead to this issue, particularly an unhealthy root system. Some causes of an unhealthy root system include overly-compacted soil, recent tillage, root compaction and severing due to pavement or other construction, drought, and overly-saturated soils.
Potassium deficiency can contribute to leaf scorch. Since plants need potassium to move water, they cannot properly move water when there is a lack of potassium.
Too much fertilizer can also cause leaf scorch symptoms. The accumulation of salts (including nutrient salts from fertilizers, as well as salt water) accumulate at the leaf margins and may build up to concentrations that burn the tissues.
Solutions
The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms.
- Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves.
- Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement.
- Protect trees from severe root damage of nearby construction and excavation.
- If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach.
- If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry.
- Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections.
- If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.
Prevention
- Physiological leaf scorch is best avoided by making sure your plants have a healthy, functional root system and access to enough water. Water regularly, especially on the mornings of excessively hot, sunny days. Deep, infrequent irrigation is better than shallow, frequent irrigation.
- Have your soil tested and apply the proper nutrients. Be sure to not over-apply fertilizers.
- Make sure your plants’ roots have room to expand. Avoid compacted soil as well and avoid paving areas above the root zone. Do not till or disturb the soil where plant roots are growing.
- Plant new trees and shrubs in the fall, so that they have the maximum amount of time to become established before the environmental stresses of the next summer.
- Remove any dead or dying plant tissue that may harbor secondary infections.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
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.
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
- Extreme heat and dry weather (when growing outdoors)
- Grow lights or indoor lighting that is too bright or intense for the type of plant
- Using fast-draining growing media such as sand
Solutions
The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with.
Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock.
In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Prevention
Always check the soil before watering. If the top inch of soil feels moist, though not wet, the watering is perfect. If it’s dry, water it immediately. If it feels soggy, you avoid watering until it dries out a bit more.
Also, make sure the lighting is sufficient for the species. Plants grow faster and need more water when there is intense light or lots of heat. Being aware of these conditions and modifying them, if possible, is a good way to prevent underwatering. Many container plants are potted in soil mixtures mean to be well-draining. Adding materials that retain moisture, like compost or peat moss, can also prevent these symptoms.
Other tips to prevent underwatering include:
- Choose pots with adequately-sized drainage holes
- Avoid warm temperatures
- Use large pots with additional soil (these take longer to dry out)
- Avoid terracotta pots, which lose water quickly

Common Pests & Diseases
Common issues for Royal poinciana based on 10 million real cases
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.

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.

Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.

Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Solutions: The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms. Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves. Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement. Protect trees from severe root damage of nearby construction and excavation. If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach. If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry. Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections. If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.

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.
Learn More ![more]()
Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.

Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions
Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control.
Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees.
- Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree.
- Contact an arborist for best control practices regarding infected trees.
- To properly control longhorn beetles, all host plants in a given area must be treated.
- Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Prevention
- Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
- Check with local tree companies about which tree species have fewer problems.
- Avoid moving firewood as this can introduce exotic longhorn beetles.
- Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.

Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
- Both leaves and blossom on the tips of branches will go brown and wither.
- Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
- Any fruit that does appear will turn wrinkled and fail to develop.
- Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.
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.
Prevention
Preventative measures include:
- Ensuring adequate spacing between plants or trees.
- Staking plants that are prone to tumbling to prevent moisture or humidity build up.
- Prune correctly so that there is adequate air movement and remove any dead or diseased branches that may carry spores.
- Practice good plant hygiene by removing fallen material and destroying it as soon as possible.

Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
- Not enough water. A lack of water will lead to dry plant tissue.
- Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
- Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
- Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
- Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
- Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
- Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
- Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
- Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
- Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
- Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
- Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
- Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
- Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention involves providing your plant with the proper environment.
- Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
- Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
- Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
- Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Overview
Leaf scorch refers to two general conditions: physiological leaf scorch and bacterial leaf scorch. It causes leaves to discolor starting along the margins, and eventually die.
Leaf scorch development is most common in the hot, dry season, becoming most noticeable in late summer. However, it can occur at other times of the year. It most often affects young trees and shrubs, but it can also affect flowers, vegetables, and other plants.
Leaf scorch can get progressively worse over multiple seasons. If the root causes are not addressed, leaf scorch can lead to plant death.
While you cannot reverse the damage caused by physiological leaf scorch, you can prevent further damage. With proper management, plants will fully recover. However, there is no cure for bacterial leaf scorch, which is a systemic infection.
Symptom Analysis
- Yellow, brown, or blackened leaves starting with the leaf margins
- Dying twig tips on trees and shrubs as leaves die and fall
- Often there is a bright yellow border line between the dead and living leaf tissue
Disease Cause
There are numerous contributing causes of leaf scorch.
Bacterial leaf scorch is caused by the bacterium Xylella fastidiosa. The bacteria block the xylem vessels, preventing water movement. Symptoms may vary across species.
Physiological leaf scorch most commonly occurs when a plant cannot take up enough water. Numerous conditions can lead to this issue, particularly an unhealthy root system. Some causes of an unhealthy root system include overly-compacted soil, recent tillage, root compaction and severing due to pavement or other construction, drought, and overly-saturated soils.
Potassium deficiency can contribute to leaf scorch. Since plants need potassium to move water, they cannot properly move water when there is a lack of potassium.
Too much fertilizer can also cause leaf scorch symptoms. The accumulation of salts (including nutrient salts from fertilizers, as well as salt water) accumulate at the leaf margins and may build up to concentrations that burn the tissues.
Solutions
The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms.
- Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves.
- Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement.
- Protect trees from severe root damage of nearby construction and excavation.
- If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach.
- If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry.
- Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections.
- If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.
Prevention
- Physiological leaf scorch is best avoided by making sure your plants have a healthy, functional root system and access to enough water. Water regularly, especially on the mornings of excessively hot, sunny days. Deep, infrequent irrigation is better than shallow, frequent irrigation.
- Have your soil tested and apply the proper nutrients. Be sure to not over-apply fertilizers.
- Make sure your plants’ roots have room to expand. Avoid compacted soil as well and avoid paving areas above the root zone. Do not till or disturb the soil where plant roots are growing.
- Plant new trees and shrubs in the fall, so that they have the maximum amount of time to become established before the environmental stresses of the next summer.
- Remove any dead or dying plant tissue that may harbor secondary infections.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
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.
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
- Extreme heat and dry weather (when growing outdoors)
- Grow lights or indoor lighting that is too bright or intense for the type of plant
- Using fast-draining growing media such as sand
Solutions
The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with.
Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock.
In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Prevention
Always check the soil before watering. If the top inch of soil feels moist, though not wet, the watering is perfect. If it’s dry, water it immediately. If it feels soggy, you avoid watering until it dries out a bit more.
Also, make sure the lighting is sufficient for the species. Plants grow faster and need more water when there is intense light or lots of heat. Being aware of these conditions and modifying them, if possible, is a good way to prevent underwatering. Many container plants are potted in soil mixtures mean to be well-draining. Adding materials that retain moisture, like compost or peat moss, can also prevent these symptoms.
Other tips to prevent underwatering include:
- Choose pots with adequately-sized drainage holes
- Avoid warm temperatures
- Use large pots with additional soil (these take longer to dry out)
- Avoid terracotta pots, which lose water quickly
