Banana Tree Problems
Banana Tree Leaves Turning Yellow
Banana leaves turn yellow for a variety of reasons. A few possibilities are a lack of nitrogen, poor drainage, over-fertilization, or fungal infection that could be damaging the leaves.
Banana Tree Leaves Turning Brown
It sounds like there’s an issue with the plant’s water supply. Brown leaves can also be a sign of disease or even banana weevils.
There are a few things to try before giving up on the plant.
Lack of water – check the soil around the base of the tree for signs that it might need a drink.
Lack of nitrogen – in the early stages will cause younger leaves to turn yellow, but older leaves will usually maintain a green coloration.
Numerous diseases – banana trees are very prone to bacterial rot and leaf spot disease, which can cause leaf deterioration.
Study your plant closely, and if you suspect an illness is present, examine it closely and cut away any infected leaves before they spread the disease to the rest of the plant.
Banana Tree Leaves Turning Black
The leaves of banana trees can turn black for multiple reasons. The most common cause though is black Sigatoka disease, due to an infection by the fungus Pseudocercospora fijiensis. This organism multiplies so quickly inside banana leaves that they blacken in patches or become totally black, and premature death soon follows.
Banana Tree Leaves Folding
The leaves on a banana tree fold in order to protect the tree from excessive heat and lack of water. If you notice that your plant is wilted or drooping, you may want to check if there is adequate moisture in the soil.
Banana Tree Leaves Splitting
Banana Tree Leaves Splitting can happen at any time. It’s common on larger mature leaves, but it can also be caused by low humidity.
As the leaf matures, it starts to dry out and will sometimes split partially or completely in half. The condition is usually associated with a decrease in relative humidity
Plus, as a banana tree’s leaves mature, various environmental conditions such as temperature, wind speed, and physical contact with other plants can also cause a banana tree’s leaves to split.
Banana Tree Leaves Drooping
The leaves of a banana tree will droop when they are not receiving enough water. Drooping leaves could also be caused by heatwave and the plant is just trying to conserve moisture.
Freshly transplanted banana trees will also droop for a few days due to transplant shock, and this will usually rectify itself once the root system bounces back and starts to develop.
Banana Tree Not Fruiting
A banana tree, not fruiting is usually caused by a lack of phosphorus or potassium. And it can also be caused by soils that lack organic matter or retain excess moisture.
Banana Tree Not Growing
It sounds like your banana tree may be experiencing low nitrogen levels or poor environmental conditions.
Nitrogen deficiency can also result in stunted growth, delayed fruit development, and poor-tasting fruit.
If you’ve already applied fertilizer without success, it may be time to consider repotting the plant into fresh soil in a new location with more access to moisture and light.
Banana Tree Not Getting Taller
Lack of light or nutrients can stunt a banana tree. Without light, the plant will not be able to photosynthesize and ultimately grow taller.
