Wash several seeds to remove fruit matter, which may inhibit growth. Fold the seeds in a paper towel and place the towel in a plastic bag. Store the bag in a refrigerator for 3 to 4 weeks to prepare the seeds for sprouting.
Put the seeds in a cup or bowl of water. Remove the seeds that float, as these are dead, and soak the ones that sink for three to four hours to soften the husks.
Fill 6-inch pots with drainage holes three-quarters full of loose, crumbly organic compost. Water the compost to moisten it, then push the seeds 1 inch into the soil. Give each seed its own pot for adequate space.
Put the pots in warm, sunny sites and keep the top 2 inches of soil consistently moist. Expect germination in four to six weeks.
