What to Consider When Choosing the Best Citrus Fertilizer

The fertilizer that you apply to your citrus tree should be the one that addresses the specific need of the trees or the soil. You should also consider the age of a tree and when it was planted. Here are some of the things to keep in mind as you shop for fertilizer for citrus trees:

1. The Chemical Content of the Fertilizers

most of the nutrients trees get from the soil, and nitrogen, potassium, and phosphorus are the elements that citrus trees need the most, and it is designated as NPK ( Nitrogen, potassium, phosphorus) in commercial fertilizers bags.

Different Fertilizers have different percentage compositions of these three elements, and for you to determine the best formula for your soil depends on which is deficient in your soil, and a simple soil test will reveal which eleme t is deficient and hence needs to be supplied by the fertilizer.

2. The Type of Fertilizers, be it Organic or Inorganic:

organic fertilizers are those fertilizers sourced from simple organic materials around us, like compost, poultry manure, and farmyard manure. These fertilizers do not have any chemicals that are harmful to the environment.

Organic fertilizers are made from synthetic ingredients like potassium, nitrogen, sulfur, phosphorus, etc. It is the most common type of fertilizer probably because it is cheaper and readily available

3. The Fertilizer Form

There are three main forms that fertilizers come in: granular, liquid, and spike; each has its strengths and drawbacks. Liquid fertilizers are ready-to-use, even though you will have to dilute them to the right concentration, and then you can then spray them on the soil.

Granular fertilizers come as pellets placed on the soul near the citrus trees, and afterward, a shovel or rake is used to work the fertilizers into the soil. 

All you need to do for spikes is to drive them into the soil around the citrus tree, and it will gradually release fertilizer for months.

4. The Stage of Growth of the Tree:

The amount of fertilizer a tree needs varies with the tree’s age. Newly planted trees less than two years old do not need fertilizer, just watering them regularly is all you need at that stage, but as they age, they will need more fertilizer.

5. The Effect You Want on Your Tree:

If you are looking for a citrus tree that uses root development, ample blossoms, and healthy foliage, you will need a phosphorus-rich fertilizer. Testing the soul is the best bet in determining which soil nutrient is deficient and needs supplementing.
