The pomegranate (Punica granatum L.), native to southern Asia, has been cultivated since ancient times. Generally allowed to grow in its natural, shrub form, it can be trained to grow as a small tree. The pomegranate tree thrives in warm, Mediterranean climates and the fruit is ready to harvest in August or September. The pomegranate seeds you plant may not produce fruit exactly the same as the parent plant.
Add moistened potting soil to the planting pots.
Place three pomegranate seeds on the surface of the soil in each pot. Place them an equal distance apart.
Cover the pots with plastic wrap, or put the pots in sealed plastic bags and place them in an area that remains between 70 and 80 degrees Fahrenheit. Check the soil periodically and add water as needed to ensure that the soil remains moist. The pomegranate seeds will sprout within six weeks.
Remove all turf and weeds from within a 3-foot radius of the outdoor planting area, which should be in a sunny location.
Transplant the pomegranate seedlings into the garden eight weeks after they sprout. Dig holes the same depth and twice the width of the pots in which they germinated. Space the seedlings 6 to 8 feet apart.
Place the roots of the seedlings into the holes and pack the soil around them. Water until the soil is saturated and water every three days for the first three weeks. Gradually taper off the frequency of irrigation until you are watering every week to 10 days.
Fertilize the pomegranate seedlings at the first sign of new growth. Give each plant 1/2 cup of ammonium sulfate, scratched into the top 1 inch of the soil. Water until the soil is saturated after fertilizing. Supply the same amount of fertilizer three more times during the growing season.
