Fertilization of Citrus Trees

Citrus trees flourish with a high-nitrogen fertilizer that also has some phosphorus. Fertilizers designed specifically for citrus trees are readily available.

Fertilizers

Fertilizers contain macronutrients essential for healthy plants. Typically, fertilizers contain some combination of nitrogen, phosphorus and potassium.

Macronutrients

Nitrogen helps plants grow quickly. Phosphorus is beneficial for healthy roots and helps plants bloom and flower.

How Often

Citrus fertilizing is customarily done every one to two months during the spring and summer, and two to three months during fall and winter. Establishing a more regular regime will depend on trial and error. Trees that are lush and maturing in a healthy way need to be fertilized less often than unhealthy ones.

Varieties

Citrus fertilizers come in two varieties: either sprayed on the leaves, or through the soil. The former is advisable for potted plants, while the latter is best for in-ground citrus trees

Precautions

Fertilizing too often can often produce inferior fruit and “burn” the leaves. Fertilize often enough to keep the tree healthy, without damaging it.
