Best Fertilizer for Fruit Trees

Fruit trees need to be fertilized to ensure their continued growth and fruit-bearing. Proper pruning and the addition of a good fertilizer at the right times of year will ensure that your fruit trees remain in a productive status.

Therefore, in this article, we will look at some of the best fertilizers for fruit trees ideal for various fruit trees.

Fertilizing Your Fruit Trees

  • Fertilizing Fruit Trees – When you first plant a fruit tree, the idea is to encourage the tree to grow toots by maintaining even soil moisture in the soil of good quality. One or two years after your fruit trees have found their feet, you will fertilize them for strong and steady growth. High Nitrogen fertilizers are ideal, yet heavy rains and watering may easily wash them away. Therefore, mostly mulch and compost are used for fruit trees which feed the soil and release slowly.
  • Feeding Mature Fruit trees – Most larger and older fruit trees outgrow being mulched and usually end up with an orchard floor covered in low weeds and grasses. Using fertilizer sticks is a much better method to feed older fruit trees. Keep in mind that excess nitrogen may affect the color of apples. For older fruit trees, you need a form of slow-release fertilizer that you can place a bit deeper to reach the tree’s roots.

Nutrient Deficiencies in Fruit Trees

Should your fruit trees struggle despite your pruning, fertilizing, and feeding efforts, you may need something else.

A Spray containing liquid kelp may be the first remedy to try.
Kelp and seaweed sprays contain various nutrients that fruit trees can take up through their leaves as a foliar feed.
The best time to apply a kelp spray I usually during spring after the new leaves have appeared.

Features of a Good Fertilizer for Fruit Trees

Most fruit trees are required to be fertilized with a certain amount of nitrogen.
You can fertilize stone fruit tree types such as peach, cherry, plum, and nectarine trees with a maximum of 1/8 pound of nitrogen per inch of trunk diameter of the fruit tree.

Whereas Apple and pear fruit trees need a 1/10th pound of nitrogen per inch of the tree’s trunk diameter.

Besides this, there are a few other ingredients to look for in a good fertilizer for your fruit trees;

  • Zinc – Zinc spray can be used, especially in Colorado, where there is usually a deficiency. Spraying the trees before buds break in the spring is ideal. However, you should avoid this for apples before and after the application of horticultural and dormant oil.
  • Iron – When there is iron deficiency in a fruit tree, you will see that the leaves will be yellow or light green and the ends of the branches, with a network of dark green veins. Margin leaf burn may also be evident in this case. The iron deficiency may lead to reduced fruit yields and poorly colored fruits with a flat taste. You will need to supplement the organic content of the soil in this case and also avoid overirrigation.
  • Calcium – If you have noticed, bitter pots and cork spots in apples are a direct result of the tree’s ability to move adequate amounts of calcium to the fruits of the tree. Trees that are young, over irrigated, and overfertilized may be more susceptible to calcium deficiency. Calcium sprays can add calcium chloride to water at a rate of 3 to 4 pounds per 100 gallons of water. You can apply Calcium spray in mid-June, July, and August if needed.
  • Other Nutrients – Other than these nutrients and nitrogen’s, foliar sprays of micronutrients may give some remediation for the season if started in April-May then continued through up to June-July. Most water-soluble fertilizers can easily be used for treatment.

Nitrogen and most other nutrients can be broadcast over the ground area around the fruit trees and watered in. This is, of course, except for zinc.

Never apply fertilizer directly against the tree’s trunk, and make sure to spread it out evenly. You may use foliar materials in the appropriate calculations and material types.
