Quince Leaves Turning Brown: Causes & Fixes

Quinces are one of the most interesting and super-weird fruits that are native to Eastern Asia. As for its uses, quinces have a very tense smell, they are a bit hard, and it is said that they taste like a combination of apples and pears at the same time, with a more bitter taste.

However, quince trees come from the family Rosaceae, and they are trees that require some things from you in order to be grown completely in the best way possible and bring you fruits. As some of you may already know, the leaves of a tree are the best indicator that the tree isn’t doing well. In quince trees, the leaves turn brown.

In this article, you will be able to find the reasons why quince leaves turn brown, as well as some other important information regarding the main topic.

Now, without further ado, let us get this article started!

Why Are My Quince’s Leaves Turning Brown?

Quince trees have a lot of leaves, and their main color is shiny green. However, that green can fade away really quickly because of some reasons, which are basically damaging the tree overall.

Those reasons include watering issues, lighting conditions, temperature, and pests. Let me mention something more that you may want to know about these issues!


The watering procedure is always confusing in different plants, especially when you expect from it fruits such as quinces. Whenever you water a quince tree, you can go to the condition of underwatering and overwatering. If a quince tree is either overwatered or underwatered, it shows that by having brown leaves.

How to deal with it?
In order to grow a super healthy quince tree, you should have in mind watering it twice a week, or at least remember that it needs 1 inch of water per week.


Plants cannot live without light as well, and a quince tree is no exception. It has its own living light condition and whenever it is not given properly the leaves start by having brown spots, and then the entire leaves turn brown completely.

How to deal with it?
Quince trees love a light spot, and it is definitely better if you choose at the first time to plant them in a place that has a full coverage of light and sun.


Another important factor that plays one of the main roles in quince leaves turning brown is the temperature. If quince trees stand or are planted in a place that has a super weird weather temperature, you can easily welcome brown leaves.

How to deal with it?
Just like these trees love light, they want a warm temperature as well. They can withstand low temperatures of 5°F (-15°C) but still, they grow better at higher temperatures, 77°F (25°C) and above.

Pest Infestation

Pests love quince trees meanwhile quince trees hate pests. It seems like there is a combination of love and hatred at the same time. When a quince tree is full of pests, it starts showing brown leaves, especially at the part which is nearby the roots of the tree.

How to deal with it?
As pests were another reason why leaves on quinces turn yellow, you should know that the best way of dealing with them is to take them fully out of the road. In case that won’t help and pests appear again, you can replant the tree in another place and change its soil.

Quince Leaves Turning Brown – Quince Leaf Blight

Leaf Blight is a disease that appears in different fruit trees, and quinces are no exception since it is one of the trees that can get easily infected by it. The botanical name of this disease is Diplocarpon maculatum, and it basically means and refers to the brown spots on quince leaves. Diplocarpon maculatum is also the name of the fungus that creates the brown color on the leaves.

It doesn’t only happen because of the fungus or the bacteria but it can also occur because of the soil that you are using.
Whenever treating any type of fungus in quince trees or in any other plant, you should know that there are two methods that you can use in order to properly clean the plants. Physical and chemical ones.

When it comes to physical treatment, that is meant planting the tree in another soil, which will be healthier and won’t cause any damage. It is also important that the soil shouldn’t be very dense so that it can absorb the water faster and not create overwatering problems.

Differing from the physical treatment, the chemical treatment is by using different pesticides or other chemical substances. Anyways, this method is a little bit dangerous if I can say it like that, because you may be very careful and protect the fruits and yourselves as well.

Final Words

Coming at the end, I think that quince trees are the trees that require more things, and if you don’t fulfill their needs, everything can go down, most importantly you won’t have any fruit coming from them. Dealing with quince leaves turning brown is a little bit worrying and somehow difficult, but if you take into consideration the preventions that I mentioned, you are good to go!

However, I really hope that this article will help you find out what may cause brown leaves on a quince tree and the ways how to deal with them!
