Nut & Fruit Tree Fertilizer

Growing your own fruits and nuts can be rewarding.

Whether you are growing one fruit or nut tree or planting an orchard, the type of fertilization you need depends on a variety of factors. Soil tests are pivotal in fertilization.

Pre-Planting Fertilization and Soil Tests

Digging up and testing soil samples is pivotal.

Take a soil sample to find out your soil's pH and nutrient levels. A soil pH of 6.0 to 6.5 is best for fruit trees. Add phosphorous and potassium if needed. Each type of fruit or nut tree may require different levels of nutrients. Each nutrient will also result in different conditions if deficient or if the level is too high.

Planting Time

Young trees require special fertilization.

Do not apply fertilizers into the planting hole or too close to the trunk, particularly nitrogen, as it can burn the roots. Instead, apply the fertilizer 10 to 12 inches from the trunk.

Established Trees

Mature, fruit-bearing trees are a result of proper care and fertilization.

Apply fertilizer to the soil only if rain or watering will help disperse the fertilizer into the soil. Another method of applying fertilizer is to create 6-inch-deep holes 12 to 18 inches apart and apply fertilizer into the holes. For established trees, apply fertilizer from near the trunk out to the drip line. Once the tree is established, take soil tests every fourth or fifth year to determine your nutrient levels and pH.
