Nutrient Deficiencies in Palm Trees<\/h2>\n

Palm trees are rather sensitive plants when it comes to the nutritional needs of their roots. When the proper nutrients are not provided the palm leaves start to show discoloration due to nutrient deficiencies. Brown leaves can indicate insufficient nutrients, environmental damage, pests, diseases, and more.
\nOne of the most common causes of brown leaves on a palm tree is a symptom of nutrient deficiency. The lack of essential minerals and vitamins can cause the relatively healthy leaves on a palm tree to gradually turn brown due to the lack of proper nutrition. Essential nutrients required by the palm tree include nitrogen, potassium, phosphorus and magnesium. If a palm tree is not receiving enough of these vital elements, it will start to show signs of distress.
\nWhen the palm tree is not getting the proper amount of nitrogen the plant will become deficient in chlorophyll, the pigment which gives leaves their healthy and characteristic green color. With the lack of chlorophyll, the leaves will start to turn yellow and eventually brown when more of the green pigment dislodges from the leaves. The same thing happens with deficiencies of magnesium and iron, however, the shade of brown that occurs in the leaves might be slightly darker or lighter depending on the extent and degree of the deficiency.
\nWhen nitrogen is not supplied in ample amounts, the tips and edges of the leaflets will become increasingly brown, leading to necrosis or death of certain parts of the leaves. Potassium deficiency, which is sometimes confused with nitrogen deficiencies, can look similar but often exhibits a few differences. For instance, potassium deficiencies will cause necrosis in the center of the leaves, not just the edges.<\/p>\n

Potting Soil Build-Up <\/h2>\n

In some cases, brown leaves on a palm tree can be caused by a buildup of fertilizer and salts in the soil of the pot or container in which the palm tree is planted. This can happen when the same soil is used in a potted plant for over two years, which often leads to the buildup of depleted salts and other toxins which can be detrimental when not removed. The buildup of toxins slows down the growth of the palm tree and its absorption of the essential nutrients necessary for healthy growth.
\nIt is important to repot a potted plant then at least every two years to remove these toxins, especially if the palm tree is showing signs of distress such as discolored leaves. Additionally, if you have a very large palm tree which cannot be repotted every two years, then it must be fertilized regularly and you have to monitor the potting soil for any toxins which may have accumulated over time. <\/p>\n

Environmental Damage <\/h2>\n

In some cases, brown leaves on a palm tree can be the result of environmental damage. Too much direct sunlight or cold temperatures can cause the leaves of a palm tree to turn yellow and then brown. Uneven watering or over-watering can also cause the leaves to discolor, especially if this is done sporadically or inconsistently. As well, high levels of air pollution or airborne pollutants can create discoloration in the leaves of a palm tree.
\nIf the palm tree is exposed to cold temperatures in winter, it can start to show signs of frost damage. This often causes the leaf tips to become discolored and eventually they turn brown and then black as the tissue at the tips of the leaves die. Additionally, too much exposure to direct sun can cause the leaves to become scorched, which will also lead to brown discoloration.<\/p>\n

Pests & Diseases <\/h2>\n

In some cases, brown leaves on a palm tree can be the result of a pest infestation or a disease. The most common pest which affects palm trees is the red palm mite, this pest often causes discoloration of the leaves as well as yellow or a slimy substance drooping from the tips of the leaves.
\nAlso, disease can be present on a palm tree, some common diseases include fusarium wilt and Thielaviopsis butt rot. If a palm tree is infected with one of these diseases the leaves can start to turn yellow and then brown as the disease progresses. These diseases have to be treated as soon as possible to avoid further damage to the tree.<\/p>\n
