How To Choose The Best Fertilizers For Fruit Trees?

Type

  • Liquid and granulated are the two major types of fertilizers for fruit trees. Effective yet easy-to-prepare, liquid fertilizers are highly recommended for most gardening applications thanks to their convenience. However, they tend to cost more than granulated fertilizers. Moreover, if you are in search of plant food that nourishes your trees for all season long without having to reapply, slow-release granulated organic fertilizer is a better choice.

Fertilizer Analysis

  • Most fruit tree fertilizers consist of a blend of NPK, referring to nitrogen, phosphorous, and potassium. However, the NPK ratio printed on each fertilizer’s package indicates the nutrient percentage per pound of product, not the exact amount. N, P and K. For instance, if the NPK listed on the bag is 7-10-12, meaning 7% nitrogen, 10% phosphorous, and 12% potassium, then there is 0.07 pounds of actual nitrogen, 0.1 pounds of actual phosphorous, and 0.12 pounds of actual potassium for every pound of this fertilizer.
  • The best fertilizer for fruit trees should contain a balanced ratio of these three ingredients. For example, 12-12-12 and 10-10-10 make the safest fertilizer to use on most fruit trees.
  • Let’s take a closer look at these trace elements that help your fruit trees properly develop!

Nitrogen

  • Most fruit trees prefer organic fertilizer high in nitrogen that makes their leaves green which is essential for green growth, photosynthesis, and general growth. The best time to feed your trees with a high-nitrogen fertilizer is in early spring when the buds haven’t broken and only if they don’t grow satisfactorily. Note that too much nitrogen can burn the plants and encourage more leaf formation than fruit production.

Phosphorus

  • Phosphorus helps transfer energy to all tree parts for strong root and flower development. As this ingredient cannot spread through the plant ground fast, it should be included in all fruit tree fertilizer.

Potassium

  • Another essential ingredient in plant food is potassium which supports water regulation water inside and outside the tree’s cells.
