How Often Do I Fertilize Newly Planted Citrus Trees?

Citrus trees should not be fertilized during the winter.

The Spanish introduced citrus fruits to the United States in the 16th century. Since then, citrus has become one of the most popular and valuable crops. Planting your own grapefruit, orange, lime or other citrus trees gives you an inexpensive and accessible harvest right outside your door.

After Planting

According to Texas A&M Extension, a newly planted citrus tree should not be fertilized until after it begins new growth. This gives the tree time to become established. It usually takes about three weeks after planting for the tree's buds to begin to swell.

When to Apply

After the tree is established, it should be fertilized every four to six weeks from early spring through October. The fertilizer should be spread on the ground at least 12 inches from the tree's trunk, then watered in thoroughly, the extension says. According to the University of Florida, water is the most important requirement for young citrus trees, even more so than fertilizer.

What Kind

The University of Florida recommends using an 8-8-8 fertilizer that also contains nutrients such as copper, boron, magnesium and manganese. You'll find the list of macro- and micronutrients on the front of the fertilizer bag.
