If you're familiar with pomegranates, you probably think of them as large bushes that can take on a tree-like appearance and grow to 30 feet. But there is also a variety of dwarf pomegranate that only grows to about 3 feet, loves the indoors and will bloom and produce fruit. It's called Punica granatum var. nana, or simply, a dwarf pomegranate. It requires very little special care to grow this beautiful plant in your own home.
Obtain a large growing container at least 18 inches deep to accommodate the dwarf pomegranate's large root system.
Fill the growing pot approximately 3/4 full with a mixture of 2 parts potting soil and 1 part compost.
Dig out an area to accommodate the pomegranate's root ball.
Place the pomegranate in the pot and cover approximately 1/2 of the root ball with the soil mixture. Water well. Add more soil mixture until the root ball is covered, pressing the soil firmly around the plant. Water once again.
Put the pot in a warm and sunny place. Dwarf pomegranates should have several hours of direct sunlight each day.
Fill a shallow bowl with gravel and add water until it is just below the level of the gravel. Place your growing pot with your pomegranate on top of the gravel. The growing pot should not be setting directly in the water or soaking up the water--the water is merely to add humidity to the air.
Mist the plant every day or every other day. Keep the soil damp but not overly wet.
Fertilize your pomegranate every 2 weeks using a fruit-tree fertilizer, following the manufacturer's directions.
