Why Are The Leaves On My Palm Tree Turning Brown

Palm trees are one of the most iconic images of tropical climates. But if their vibrant green leaves start turning brown, it could be the first sign that something is wrong. To prevent any further damage, it’s essential that a palm tree owner knows why this is happening – as well as a plan for helping their tree recover.

Generally speaking, brown leaves on a palm tree are the result of environmental stress. A few possible causes of such stress include salty air, nutrient deficiencies, or repotting the tree too soon after the previous one. Poorly draining soil and too much direct sunlight can also contribute to a palm tree’s distress.

Experts and palm tree owners alike can agree that it’s important for these plants to have the right balance of water, moist soil, and sun. Too much water or too little can cause a palm’s leaves to become brown. Dr. Steve Blackwell, a horticulturist and professor of urban forestry, explains that “It is important to not overwater, as it can cause the leaves to start to turn yellow and, then, brown.”

However, the root of the problem may be deeper than just water or sunlight. Julie Walton, an arborist, confirms this, saying “Drip irrigation systems can lead to salts, fertilizer, and other compounds building up in the soil and create brown leaves.” Plants need a certain level of essential nutrients like nitrogen, phosphorus and potassium for healthy growth, and a buildup of these compounds can make it difficult for palm trees to absorb the minerals they need.

But nutrient buildup may not be the only one to blame. Diseases can also cause palm leaves to turn brown. Florida summers, for instance, can be the prime season for infestations from aphids or mealybugs – and spotting the signs of their presence can help avoid further damage. William Fletcher, a biologist and palm tree expert, explains “These pests are a very common issue and can cause brown leaf tips or yellowing and browning of the entire palm tree.”

Finally, repotting a palm tree can cause some stress and if done too soon after the last, can result in brown leaves. While it’s beneficial to rejuvenate the soil of a mature palm tree and replace the nutrients, repotting should be done no more than every two to four years. If done again too soon, the new soil mix may be too nutrient-rich, resulting in brown leaves.

Caring for Brown Leaves

In the event of brown leaves, a palm tree owner should act immediately. Start by testing the soil pH and soil salinity levels. If these are normal, move on to inspecting the tree for pests. If no pests are present, then providing the tree with extra care and attention can help it make a successful recovery.

If salinity or pH levels are too high for the palm tree, counter it by adjusting the soil and giving the palm tree more water. More water can help flush out salty compounds from the soil and help the tree regain health. However, too much water can be just as bad if the soil will not drain properly because it will cause the palm tree’s roots to rot. In cases like this, allow the soil to dry out and watch the palm tree for signs of health.

For nutrient deficiencies, experts suggest introducing extra nutrients directly to the soil. If the soil around the palm tree is too erosive or dense for it to absorb nutrients, experts suggest lightening it up with mulch to help increase its absorbency.In either case, fertilizers that contain a combination of nitrogen, phosphorus, and potassium will help the tree regain balance.

Controlling Pests

If a palm tree owner identifies pests like aphids or mealybugs on their tree, the best-case scenario is to eliminate them without using chemical sprays. Experts suggest using insecticidal soap or neem oil to keep the pests in check; both are organic and safe to use on palm trees. If the infestation is severe, insecticides may be used as a last resort.

If a palm tree owner’s tree has become significantly distressed, they should consult with a horticultural expert. An expert can take a look at the tree and provide an accurate diagnosis and treatment plan. They’ll be able to accurately detect the source of the problem and provide the best course of action for helping the tree recover.

By providing the right balance of water, light, and nutrients can help a palm tree recover from stress and brown leaves. However, if the stress is caused by pests, nutrient deficiencies, or repotting too soon, further steps may need to be taken. Understanding the source of the problem, inspecting for pests, and getting advice from a horticultural expert can guarantee that a palm tree can recover and become healthy again.


Repotting should not be taken lightly; it’s an important strategy in caring for a healthy palm tree. When it’s time to repot, be sure to introduce a soil mix that’s designed for palm trees and be mindful of the tree’s rooting system. If the root ball was disturbed, an anti-transplant shock product can be applied to the tree to help it recover.

Palm tree fertilizer can also help when repotting. It’s essential to add extra phosphorous to the new soil because it helps with a palm tree’s root development and can reduce the replanting stress. Lastly, the soil mix should have good drainage and be able to retain a certain amount of moisture for the tree to survive.

A good rule of thumb for repotting a palm tree is to make sure it’s in an appropriate container size and soil mix. If a palm tree needs repotting in its current pot, take extra care not to damage the roots. Once the potting soil has been added, spread it evenly and give it enough water.

The Benefits of Pruning

In addition to repotting, pruning a palm tree can help it heal and recover. Removing damaged or dead leaves can improve the tree’s overall health and will give it a better chance of coming back stronger. This will also prevent further damage in the future and can help conserve water and nutrients within the tree.

While pruning can be beneficial to the health of a palm tree, it’s important to not be too aggressive with pruning. Instead, make small, careful cuts and always keep in mind the amount of foliage the tree needs for photosynthesis. Pruning can open up the canopy of the tree so that light can reach its branches and can help maintain the tree’s aesthetic appeal.


If a palm tree owner’s tree is showing signs of distress, there are several steps they can take in order to get it back on track. Salinity or pH levels should be checked, extra nutrients can be added to the soil, pests should be controlled, and the tree should be pruned and repotted appropriately. Following the right steps can result in a healthy, thriving palm tree that can withstand stress and be enjoyed for years to come.
