Overview

The pomegranate (Punica granatum) is a rounded, shrub-like tree that is native to the Middle East and India. Growing up to about 20 feet tall at maturity, the pomegranate enjoys warm, semi-arid to subtropical climates, where the climate isn't very humid. Although pomegranates grow best in regions with hot summers and cool winters, the tree cannot tolerate temperatures below 15 degrees Fahrenheit. You can grow pomegranates indoors in containers, but you'll need to provide plenty of sunlight during the growing season in order for the trees to produce fruits.

Step 1

Repot your pomegranate into a container that has drainage holes in the bottom and is at least 1 ½ times the width and height of the nursery container. Fill the new pot with well-draining, all-purpose potting soil and plant the pomegranate at the same depth it was planted in the nursery container.

Step 2

Place the pomegranate tree in the warmest and sunniest part of your home or greenhouse. The pomegranate needs plenty of sunlight in order to produce fruit, so set the tree outdoors in full sun if you can during the summer months.

Step 3

Water your pomegranate tree once or twice each week throughout the growing season to thoroughly moisten the soil. Water the pomegranate until the water drains freely from the bottom of the container. Don't allow the soil to dry out completely.

Step 4

Feed your pomegranate tree once every year in the spring with 2 to 4 ounces of ammonium sulfate or a similar high-nitrogen fertilizer. You can also spread a 2-inch-thick layer of well-rotted, aged manure or organic compost on top of the soil in the planting container each spring.

Step 5

Prune your pomegranate tree in late winter or early spring, cutting the tree back to only four or five shoots when it reaches about 24 inches tall. Remove all new growth, shoots or suckers that grow above or below the buds, which should be about 12 inches from the soil level.

Tips and Warnings

  • Your pomegranate tree will flower and grow in partial shade, but you must provide full sunlight and warmth in order to get the pomegranate to bear fruit.
