Sometimes it is just normal because the leaves are getting old or problems with watering and lacking sunlight are some other reasons.

Why Do Jackfruit Leaves Turn Yellow?

The reasons why the jackfruit leaves are turning yellow is because of watering problems, lacking sunlight, cold weather, iron and nitrogen deficiencies, pests, diseases, and transplant shock.

In order to find out the real cause of yellow leaves on jackfruit, you need to analyze and observe your tree first.

Watering Problems Causes Yellow Leaves On Jackfruit

Lacking water can cause jackfruit leaves to turn yellow. Young jackfruit in a pot needs water more often because the soil in the pot dries faster than ground soil.

Check the soil moisture before watering. You can check the soil moisture by pressing your index finger 2 inches in the potting soil.

If you feel the soil is still moist, don’t water it unless it is dry you need to water the tree.

A mature jackfruit tree is more established than young ones and can survive without water for a couple of days and weeks.


If you overwater a jackfruit tree, yellow leaves may also appear. A young tree just needs a little water compared to a mature one.

Just give enough water to a jackfruit tree and don’t overwater it. Also, when heavy rains come the tree might be soaked in water.

A potted jackfruit tree should have good drainage to prevent water to get stuck. Root rot may happen when the roots are soaked in water for a long time.

Caring for a jackfruit tree is needed to keep it healthy and thriving.

Lacking Sunlight

A jackfruit tree loves sunlight and mostly they are planted outside. Sunlight is abundant outside and it will help the tree grow excellent.

If you have a small jackfruit tree that is planted in a pot and placed indoors, you might be considering bringing it outside to get plenty of light.

When the jackfruit tree doesn’t get enough light, it cannot make its food. Make sure that a jackfruit tree is getting at least 4 hours of light especially if they are still small.

A mature jackfruit tree needs at least 6 hours or more of sunlight per day. More sunlight will help the tree improves its growth and increase fruit production.

Cold Weather

Cold weather can also cause yellow leaves on a jackfruit tree. The jackfruit tree grows well in tropical countries where sunlight is abundant.

If you are living in a place where the weather gets cold, it is likely to see yellow leaves on your jackfruit tree. This tree doesn’t tolerate much cold and it like warmer temperatures.

Aside from yellow leaves, curling leaves on a jackfruit tree may also appear. You need to place your potted jackfruit trees indoors when the weather becomes cold.

Another thing is you can use LED grow light to keep them warm. The outdoor jackfruit tree must be covered with blankets, tarps, or any protection against the cold.

Iron And Nitrogen Deficiencies

Iron and nitrogen are important to keep the leaves healthy. These elements will help increase the production of chlorophyll in the leaves.

Chlorophyll is a green pigment that makes leaves green and it works to convert sunlight into food.

Because of the chlorophyll, the plant is able to make its food. When there are iron and nitrogen deficiencies, the tree leaves will turn yellow.

To keep leaves healthy improve the iron and nitrogen by applying nutrients into the soil.

Other elements like potassium and phosphorus are also important and will help increase fruit production.

Transplant Shock

Seeing yellow leaves on your jackfruit tree? Then it might be because of transplant shock.

Transplant shock is common for trees and you need to be careful to keep the tree thriving.

If you buy a potted jackfruit tree and you want it to plant in the ground, you need to water it a few minutes before transplanting.

Also, after transplanting, give it again a little water to help it establish itself better.

Also, avoid fertilizing it too early and wait for a few weeks before doing it. The tree will recover from a transplant shock a few days or a few weeks after transplanting.

It is much better to transplant jackfruit seedlings when they are still too small. Mature trees are more prone to transplant shock than small trees.

Pests And Diseases

If you are seeing pests and diseases on your jackfruit tree, you need to control them as early as possible.

Pests and diseases can also cause yellow leaves which can affect tree growth. By keeping the tree pests and diseases free, the jackfruit lifespan will be in good condition.

Not just the leaves, but other parts of jackfruit can also be affected because of pests and diseases.

You need to control them as early as possible to prevent further damage.

Aging Jackfruit Leaves

It is normal to see yellow leaves on any plant and tree. Commonly these yellow leaves are old leaves.

It is normal to see these kinds of leaves because it is part of their growth. It is a cycle for the leaves to grow and then get old.

The young leaves will grow and after a few weeks and months, they turn yellow and eventually jackfruit leaves turn brown.

Those age leaves are dropping when the time has come. You cannot stop the leaves’ natural changes.

Those are some of the reasons why jackfruit leaves turn yellow. Watering problems, cold weather, lacking sunlight, pests, diseases, transplant shock, and iron and nitrogen deficiencies are some of the reasons why jackfruit leaves turn yellow.
