Fruits Fertilizer

Which fertilizer is suitable for fruit trees?

Most tree fertilizers contain a mixture of nitrogen, phosphorus, potassium or NPK.

You will usually see the ratio of these ingredients on the bag. Usually 15-15-15 or 17-17-17. The balanced ratio of these three substances makes the fertilizer safe to use on most trees.

Trees need some trace elements to help them develop properly. Let's take a closer look at all the points.


Fruit trees really like high-nitrogen fertilizers. Nitrogen is one of the main nutrients in the growth of all plants because it helps to make the leaves green, which is necessary for photosynthesis. This is the most important during general growth and leaf formation.

Nitrogen is easily available in most organic fertilizers and composts (such as blood meal or manure), although it is recommended to use fertilizers specifically designed for fruit trees because it also takes into account the needs of all other minerals.


All plants need phosphorus to transfer energy from one part of the tree to another and help form strong roots and flowers. Phosphorus does not spread to the ground quickly, which is why phosphorus should be a component of every tree fertilizer.


Potassium is important because it helps regulate the water pressure inside and outside the tree cells. It also aids metabolism and is a key component of strong root development.

Other major nutrients

In addition to nitrogen, phosphorus and potassium, plants also need calcium to enhance cell walls and overall health, magnesium to form and regulate seeds, and sulfur to produce chlorophyll for photosynthesis.

Trace elements

The following are some essential trace elements of fruit trees and their functions:

Zinc-seed production

Manganese-chlorophyll production

Iron-chlorophyll production

Copper-helps metabolize nitrogen

Molybdenum – helps metabolize nitrogen

Chlorine-needed for photosynthesis

Boron-promote cell growth and regulate nutrient absorption

If any of these trace elements are lacking, you should be able to tell.

For example, you may notice that the leaves turn yellow or pale. The best way to find the problem is to test the soil. In this way, you know what to replace.
