Why Are My Banana Plant Leaves Splitting? (3 Interesting Leafy Facts)

If you have your own tree, have you ever wondered why my banana plant leaves are splitting?

Is it a sign of disease?

Are you doing something wrong when looking after your banana plant?

Or perhaps, it’s just a natural occurrence.

Will the damaged leaves affect the fruit in any way?

And, of course, if it is a sign of a problem, you need to know how to prevent it.

Let’s get to the bottom of the split banana leaves mystery.

There are three reasons why your banana plant leaves are splitting. Typically, it is a natural response to high winds and is common in plants with large leaves. By allowing the leaves to shred, the wind passes through the banana plant rather than pulling it over. The second cause may be a lack of humidity. Water and humidity are necessary for healthy banana plant growth. And finally, it is just an indication that it is an older leaf. Regardless of the cause, split banana leaves are not a problem and do not damage the plant or the fruit. 

1. Is the Weather Affecting My Banana Plant?

One of the main causes of a banana plant’s leaves splitting is due to high winds.

Most large plants have the same response to windy weather.

The leaves split or shred to allow the strong wind to pass through, leaving the banana plant otherwise unharmed.

If the banana leaves didn’t split, the wind could pull the plant over and even uproot it.

When first planting your banana tree, try and ensure it is sheltered from the wind.

If this isn’t possible, then don’t worry about the split leaves; they don’t need to be removed.

The level of humidity is also important to the banana plant.

Low humidity can be another cause of the leaves’ splitting.

It can be an indication that the banana plant is not getting enough water.

As you can imagine, bananas usually grow in tropical, humid areas with frequent rainfall.

You can mist the leaves of your banana plant to recreate the atmosphere it prefers.

And ensure you give it enough water, but then again, not too much!

Watering two or three times per week should be enough.

If the banana plant leaves turn brown, as opposed to splitting, it can be a sign of overwatering.

2. What Are Other Common Problems with Banana Plant Leaves?

Apart from the banana plant leaves splitting, what else can be a problem?

Banana leaves are actually quite fragile, despite their robust appearance.

When wanting to grow your own banana plant, you will undoubtedly need to transport it home or have it delivered.

The leaves will break easily, and if more than one plant is being transported, they can rub against each other.

A banana plant can also suffer from what is known as transport shock.

It will focus on survival, and this means supplying only the main stem with nutrients and water.

If the leaves are no longer supported by the banana plant, they will die.

This will only be a temporary problem, and your banana tree will soon start producing new shoots and leaves.

3. Do Banana Leaves Get Diseases and Pests?

Another issue with banana leaves is that they are susceptible to insect damage and disease, causing them to turn yellow.

Yellow banana leaves should be cut from the plant, they will not regain their former health and color.

Several diseases can affect banana plant leaves, the most common being as follows:

  • Banana Wilt: This is a lethal disease and affects the oldest leaves first. The leaves will start to turn yellow, and the disease moves quite quickly to the center of the plant. Commercial plantations will flood their fields to halt the disease.
  • Sigatoka: This is caused by a fungus and is also known as a leaf spot. The banana plant leaves become covered with small gray spots that increase in size to approximately half an inch. The only way to control the disease is to spray the leaves with mineral oil every three weeks.
  • Bunchy Top: This disease is spread by aphids and gives the banana plant leaves a unique yellow color with green dots and dashes. It has been known to wipe out entire plantations.

How to Care for Your Banana Plants

Final Thoughts

If your banana plant leaves are splitting, it could be one of three reasons.

High winds can shred or split banana leaves as a defense mechanism to stop the plant from blowing over.

Lack of humidity is a problem and will be revealed by split banana plant leaves.

Or it could simply be old age.

If the leaves are turning yellow rather than splitting, it is more likely to be caused by disease.

Don’t panic if your banana plant leaves are splitting, you can establish the cause and resolve the problem.
