Originating from southern Asia, pomegranates (Punica granatum) are small deciduous trees that produce yellow to bright-red, 4-inch-diameter fruits. Pomegranate fruits have smooth, leathery rinds and contain pink or purplish, juicy pulp with numerous seeds. Pomegranate trees are grown outdoors in tropical, subtropical and sub-temperate regions where winters are mild and summers are often hot and dry. Pomegranate trees are grown from seed or hardwood cuttings, although propagation by seed won't produce a clone of the parent tree. Pomegranate seeds germinate easily but slowly.
Peel and slice the pomegranate in half. Submerge the pomegranate fruit into a bowl of cold water to separate the seeds.
Allow the pomegranate fruit to soak in the cold water until the white membrane floats to the top. Pour the water and fruit into a strainer and pick out the seeds.
Spread the pomegranate seeds in a single layer on clean, dry paper towels. Allow the seeds to dry out for two or three days.
Fill a seed tray that has drainage holes in the bottom with a lightweight, free-draining compost mixture. Spread the pomegranate seeds on the surface of the compost, spacing the seeds about 2 inches apart.
Sprinkle a light layer of compost or vermiculite on top of the pomegranate seeds. Water the compost and seeds to lightly moisten them.
Place the seed tray into a clear plastic bag, or place a clear plastic lid on top of the seed tray. Set the seed tray in a dark spot and keep the compost at 68 to 86 degrees Fahrenheit.
Keep the compost and pomegranate seeds evenly moistened until they germinate, which can take six weeks to four months. Water the seed tray lightly once or twice a week to prevent the compost from drying out.
Remove the seed tray from the plastic bag and select the strongest seedlings after the pomegranate seeds germinate and begin to sprout. Transplant the pomegranate seedlings into 6-inch-diameter planter pots filled with a lightweight compost mixture or another soil-less potting mix.
Place the pomegranate seedlings in full to partial sunlight, such as in a south-facing window, or outdoors in the warm summer months. Water the pomegranate seedlings deeply until the water drips from the drainage holes in the bottom of the pots two or three times per week to keep the potting mixture moderately moistened.
