How & When to Fertilize Quince (2024)

The quince tree (Cydonia oblonga) is the only member of the genus and part of the rose family. While at one time it was popularly grown in home gardens, today it is more commonly grown as rootstock for pear and other fruit trees. Quince trees are maintenance-intensive, requiring heavy pruning every year. Quince trees may live for hundreds of years and, aside from pruning every year, require little maintenance. The tree is susceptible to fire blight, a disease that strikes vigorously growing trees, so it is important to not over-fertilize the tree. Quince does best when grown in U.S. Department of Agriculture plant hardiness zones 5 through 9.

Why Fertilizing Is Necessary

  1. Quince trees, like most soil-grown plants, take up nutrients through their roots. These nutrients come from a variety of sources including the breakdown of plant and animal matter, manure and fertilizer applications. Over time, soil loses nutrients through leaching, long periods of wet weather, runoff, erosion and harvesting. The development and maintenance of a healthy root system determines the success of the quince tree so maintaining the soil’s fertility is an important part of the tree’s care.

Type of Fertilizer

  1. Somewhere on the fertilizer bag or box you’ll find a set of three numbers, such as 10-10-10. The first number represents the amount of nitrogen in the fertilizer. The second and third numbers represent the amount of phosphorus and potassium, respectively. Nitrogen is responsible for lush, green foliage. Phosphorous assists in photosynthesis, the transportation of nutrients throughout the quince tree and the development of a strong root system. Potassium builds strong, healthy flowers. A 5-2-6 fertilizer formula is ideal for the quince tree as it has just enough nitrogen to help the tree develop foliage and additional potassium for the tree’s flowering and fruiting. The low phosphorous level helps avoid excessive buildup of phosphorous in the soil, which may impede the trees ability to absorb micronutrients.

When to Fertilize Quince

  1. Young quince trees (under two years old) require more frequent applications of fertilizer than older trees. Apply fertilizer to the immature tree in March, May and July. Feed the mature tree just once a year, in June, and only if a soil test confirms a nutrient deficiency in the soil. Quince trees grown in clay or sandy loam soils, watered regularly, typically don’t require fertilizer, according to master gardeners with the University of California.

How to Fertilize Quince

  1. Granular fertilizers are best applied with a broadcast spreader. Sprinkle the fertilizer completely around the quince tree, from 6 inches away from the trunk to 1 foot beyond the dripline. Granular fertilizers require water for activation, so water the fertilized area slowly and to a depth of 10 inches to soak the product into the soil.
