By Teo Spengler

If your quince fruit is cracking, you are not alone. Quince fruit split is not uncommon. It happens where one or more quinces split, creating openings through which diseases and pests can attack otherwise healthy fruit. Quince fruit split is a condition often caused by water supply issues. Read on for more information about the causes for splitting quince fruit.

Quince Fruit Tree Problems

If your quince fruit is cracking, you are probably wondering about causes for splitting quince fruit. Note that quince fruit split is neither a disease nor a reaction to a pest infection. It is caused by the tree’s growing conditions.

Causes for Splitting Quince Fruit

Water is one of the primary causes for splitting quince fruit – an irregular supply of water. Quince fruit split often occurs when there is a long dry period followed by abundant rain. The sudden generous water supply causes the fruit to swell too quickly and crack.

Given that rainfall is outside a gardener’s control, it isn’t easy to make sure your quince trees have a steady supply of water. One thing you can do is to take steps to hold the irrigation in the soil longer.

You do this by incorporating well-rotted organic matter into the soil when you plant. This is important because organic compost assists the soil to hold onto moisture, thus making it available for the plant during dry periods.

Mulching is another way you can help soil retain water. Layer about two inches of garden compost over the root area of the tree, keeping it away from the trunk and foliage. The mulch disintegrates into the soil in time, improving it.

In the meanwhile, mulch helps prevent quince fruit tree problems and, specifically, fruit split in quince by retaining moisture in the root area. Apply the layer of mulch after the spring rains.
