Citrus trees, just like all plants, require fertilizers to ensure maximum fruit yields. They are a generous flowering plant in the rue family. They produce a wide range of fruits like oranges, lemons, pomelos, limes, and grapefruits.
For a start, you need to use the right fertilizer type. The best way is to consider a specially formulated citrus fertilizer. Citrus fruits are heavy feeders and require nitrogen (N), phosphorus (P), and potassium (K).
We strongly recommend 16-4-8 fertilizer which provides all the needed nutrients and macronutrients. Some of the required micronutrients are boron, sulfur, iron, copper, manganese, and magnesium.
But knowing the right fertilizer is one thing. You need to know when to fertilize and how to fertilize the trees.
