Plumeria Sunburn: Causes, Treatment, & Prevention

Noticing that your plumeria leaves have turned a scorched orange, almost like they have been exposed to the sun for too long? Don’t fret – it’s likely that you’ve just experienced plumeria sunburn. Characteristically, any plant exposed to too much sunlight can suffer from sun damage, and plumeria is no different! Don’t worry overly much though – a bit of care and effort on your part can reverse most of the sunburn effects on plumeria in no time!

Symptoms of Plumeria Sunburn

The most obvious symptom of plumeria sunburn is the discoloration of leaves, usually a pale orange or yellow hue. This aesthetic change can be accompanied by wilting and curling of leaves. Excess sun exposure can also cause the stems to become brittle and brown spots may appear on the growing tips.

Plumeria Leaves Looking Burnt

Sometimes, even with the best intentions and care, your plumeria leaves can still look burnt. The cause of this condition is usually prolonged exposure to direct sunlight. The heat of the sun damages the delicate tissue of the leaves and stems, causing them to dry out and turn brown.

Thankfully, treating a plumeria suffering from sunburn is fairly easy. Begin by moving it out of direct sunlight into a shadier spot with indirect light. It’s also important to make sure the soil around your plant is consistently damp but not soaked – over-watering can lead to root rot which will further damage your plant’s health. Finally, you can try misting or spraying water on the leaves to help keep them hydrated.

Discolored Trunk of the Plant

The trunk of your plumeria can become discolored due to sunburn, as well. Sunburn on the trunk usually affects the outer bark tissue and can cause it to take on a dark or gray coloration. If any of the inner layers are affected, this can lead to internal rot which will require pruning in order to restore health.

Plumeria Leaves Looking Bleached

The bleaching of your plumeria leaves is also a sign of too much exposure to direct sunlight. The intense heat from the sun can cause delicate plant tissue to dry up, leading to a loss of chlorophyll and color. To prevent this from happening, make sure you give your plant some shade when it’s in direct sunlight for long periods of time. You can also mist or spray your plant with water regularly to keep its leaves hydrated.

Plumeria Leaves Looking Wilted

Wilting and curling of the leaves is another symptom of sunburn. This happens when too much direct sunlight causes your plant to become dehydrated, leading to wilting and curling up of the leaves as a defense mechanism. To prevent this from happening, make sure you water your Plumeria regularly and avoid putting it in direct sunlight for extended periods of time.

Discoloration of Leaves

Sometimes, sunburn can cause the leaves of your Plumeria to turn white or brown. Another similar symptom is brown leaf tips. This is likely due to a loss of chlorophyll caused by intense heat and direct sunlight. To prevent this from happening, make sure you move your plant out of direct sunlight when temperatures are very high or give it some shade with a sheer curtain or other material that will filter out the harsh sunlight.

Causes of Plumeria Sunburn

Plumeria sunburn is caused by too much exposure to sunlight. If the sun’s rays are too intense, or if a plant has not had enough time to adjust and acclimatize to its environment, then it can be prone to sunburn.

Too Much Direct Sunlight

Direct sunlight is essential for any plant, per the University of Connecticut. It’s especially important for a Plumeria to get at least 3-4 hours a day of direct sun in order to thrive and bloom. But be careful not to overexpose your Plumeria to too much direct sunlight, as it can cause sunburn.

Not Enough Acclimatization

Plumeria plants that have been grown indoors or in shady areas are not used to intense rays of light and may suffer from sunburn if they are suddenly exposed to direct sunlight. For this reason, it is important to slowly acclimate your plant by exposing it gradually over time rather than subjecting it directly right away.

Treating Plumeria Sunburn

If your plumeria shows signs of sunburn, the first thing you should do is move it to an area with more shade. This is especially important if the plant has recently been moved outdoors or to a sunnier spot in your home. Moving your Plumeria back into indirect sunlight and away from direct exposure will help it recover faster.

Keep an eye on Moisture Levels

You can also use mulch around the base of your Plumeria – this will help provide protection from heat exposure and keep moisture in the soil for longer periods of time. Additionally, make sure your potting soil is well-draining so that water doesn’t accumulate around the roots and leave them vulnerable to rot or other issues. Finally, keeping up a regular watering schedule and fertilizing with a balanced fertilizer every few months will help keep your Plumeria healthy and strong!

In conclusion, sunburn can be an issue for plumeria plants, but with proper care and attention to sunlight exposure, it is easily avoidable. When in doubt, move your plant back into the shade until its leaves are restored to their previous state of health. With the right combination of light and water, you’ll have a happy and healthy plumeria in no time!

Allow Leaves to Heal Naturally with Extra Care and Monitoring

Sometimes despite our best efforts, sunburn can still occur. If this is the case for your Plumeria, try to avoid pruning or cutting off any of the damaged leaves in order to allow them time and space to heal on their own. Monitor your plant closely during this healing period and be sure to adjust its light exposure accordingly – if it’s getting too much sunlight, make sure you move it back into a more shaded area as soon as possible!

Prevention Tips for Plumeria Sunburn

Acclimate Your Plant Before Moving it to Direct Sunlight

The most important thing you can do to prevent sunburn on your Plumeria is to acclimate it slowly if you are planning to move it into direct sunlight. Start by moving the plant a few feet closer each day until it reaches its intended spot in the yard or home and can tolerate the full intensity of the sun’s rays, this will help reduce stress and shock that could otherwise lead to sunburn.

Additionally, mulching around your plant provides an extra layer of protection from heat exposure and helps keep moisture in the soil for longer periods of time. Make sure your potting soil is well-draining so that water doesn’t accumulate around the

Monitor Light Levels Year Round

Finally, keep a close eye on the intensity of your Plumeria’s light exposure year-round. Especially if you live in an area with long days and intense sun during the summer months, make sure to move the plant back into more shaded areas when needed and provide any necessary protection from heat stress.

By taking these steps to prevent sunburn, you can ensure that your Plumeria stays healthy and thriving all season long! So get out there and enjoy the sunshine – just don’t forget to give your plants the extra care they need too!

Water with the Seasons Depending on Plant Needs

In addition to sunlight exposure, your Plumeria will also need regular watering to stay healthy. Watering with the changing seasons is a good way to keep your plant hydrated and happy. During the warmer months, you can water more frequently; in colder periods, cut back on watering so as not to over-saturate the soil or damage any roots.

Finally, fertilizing with a balanced fertilizer every few months will help provide essential nutrients and keep your Plumeria looking its best! With these simple tips for preventing sunburn, you can enjoy blooming, vibrant plumeria plants all summer long.


Plumeria sunburn is a common issue for those growing this tropical plant, but with proper care and attention to sunlight exposure, it can be easily avoided. To prevent sunburn on your Plumeria, acclimate the plant slowly when moving it into direct sunlight, monitor light levels year-round, provide extra protection from heat stress in the summer months, water with the changing seasons depending on plant needs, and fertilize every few months for essential nutrients. When sunburn does occur, allow leaves to heal naturally with extra care and monitoring.

Now that you know all there is to know about preventing and treating plumeria sunburn, it’s time to start putting these tips into practice. With a little extra care and attention, you can ensure the health and vibrancy of your plants in the future.
