How to Fertilize Pomegranate Trees

Pomegranate trees were first cultivated in the Middle East and grow well in warm, dry climates. In the U.S., they thrive in central California and Arizona. They can be grown in other southern U.S. areas, but may not produce fruit. Fertilize pomegranate trees regularly to maximize growth, flowering and fruit production.

Step 1

Know whether your soil is alkaline or acidic. Low acid soils have a pH above 7.5. High acid soils have a pH below 5.5. Purchase a soil test kit from a hardware store, nursery or online if you need to test yours. If you don't want to test, ask a worker at your nearby nursery for a rough estimate of soil pH in your area.

Step 2

Use a nitrogen fertilizer, such as ammonium sulfate, for alkaline soils. For acidic soils, use a neutral fertilizer, such as calcium nitrate. Fertilizing is important the first two springs after planting, but as trees mature they need less.

Step 3

Fertilize in two applications, using four ounces each time for newly planted young trees. Follow instructions included with fertilizer. After the first two years, fertilize in the fall or winter using eight ounces. Add an additional ounce each year until you reach sixteen ounces.

Step 4

Prevent zinc deficiency, which is difficult to diagnose, by applying a small amount of zinc spray to foliage. Zinc deficiency often causes yellow-mottled leaves.

Step 5

Ensure against other mineral deficiencies by liberally applying compost around base of tree several times a year. Using compost guarantees you won't have to diagnose a specific deficiency because it contains all nutrients.

Tips and Warnings

  • Don't over-fertilize because it can cause excessive growth and reduce flower and fruit production.
