When you enjoy a ripe piece of watermelon or another seeded fruit, that doesn't have to be the end of it. Save the seeds from the fruit and not only will you have a rewarding and economical experience growing, but the results will be rather tasty. Once seeds have been removed, they can be planted one or two ways. Decide which method is best for you and your space, and then you can literally enjoy the fruits of your labor.
Remove the seeds when the fruit is mature. Open the fruit and gently scrape the seeds out and then place them in a bowl. Rub the seeds in a sieve with water to remove the slimy outer coating. Rinse the seeds well under water. Spread them out onto a surface lined with paper towels and let them dry.
Plant the seeds in flats or containers to allow them to germinate after they are cleaned. Fill each container 2/3 full with a well-drained medium. Place the fruit seeds on top and cover the seeds with additional potting medium. Water the seeds and place them in an area where they will receive indirect light throughout the day. Plant the seedlings into the ground or a larger container once the dormancy period is finished and germination has begun.
Plant the clean, dry seeds directly in the ground if you prefer in the spring after all danger of frost is past. Prepare a hole to receive the seeds. Plant the seeds about three times as deep as the seed's diameter in a well-drained medium. Cover the seeds with the soil that was removed. Water the seeds following the initial planting, and keep them moist during the germination period.
