How To Choose Apple Tree Fertilizers?

The best food for apple trees choice depends on what’s the purpose behind using it. While some fertilizers offer vital nutrients to the plant for overall tree health, others encourage root development and blossom production. Some might also be formulated exquisitely to make up for the deficiencies in the soil.


Here are the considerations for choosing the best food for your apple trees.


A. Soil and pH level

Fortunately, apple trees thrive in sandy soil rich in nutrients with loam. These trees love slightly acidic soil. Hence, you must plant them in soil with a pH between 5.8 to 7 on the pH scale.


While some soil types might be in this range, many won’t be. So, if yours is more acidic or alkaline than needed, it will result in the plant’s failure to produce fruits and might also be the reason for the plant’s slow growth or poor health.


However, not all commercial fertilizers are ideal for altering your soil’s pH. So, to ensure the best outcomes, you must get a soil assessment test done, and then depending on the result, you can add compost or lime based plant food that can bring the soil closer to the apt pH level.


B. NPK ratio

When shopping for apple tree fertilizers, look at its NPK and pick a balanced one or one with a higher nitrogen component:


1. Nitrogen – It helps with branch and leaf growth. A small apple tree appreciates more nitrogen than a mature tree because its sapling is still growing.


2. Potassium– It helps boost the plant’s health by enabling it to withstand extreme temperatures or slight droughts. Potassium also helps maximize the degree of nutrient absorption.


3. Phosphorous – Phosphorous helps promote healthy and strong roots, which can help the plant on days of strong winds. Phosphorous also helps with blossom production. So, it aids in yielding an excellent harvest.


C. Select the type of fertilizer that is easy to use

Broadly, there are three kinds of fertilizers to choose from:


1. Liquid – You spray it into the ground for the plant to soak the nutrients.

2. Powdered – You can directly place these feeds into the soil around the trees. They can either be diluted for application or mixed with water.

3. Granular – These are sprinkled around the ground using a seed spreader and then watered into the ground.


D. Decide between synthetic and organic plant food.


Lastly, you choose between organic foods comprising animal or plant-based waste with other natural ingredients and synthetic fertilizers. The former has a lesser nutrient value, whereas the synthetic foods are composed of synthetic chemicals and minerals that help generate a higher yield.
