Dig holes in the ground for the transplants. Place one seeded watermelon in the first row and transplant seedless watermelons into the next two holes. Continue to stagger your plantings, with one seeded variety to every two seedless. Water the transplants in and wait, about 85-100 days, for the fruit to mature.
Simply scoop the seeds out of a watermelon, rinse them under water to remove any fruit pieces or fruit juices, and let them air-dry on a paper towel.
