Starting Watermelon Seeds Indoors

Gardeners in colder climates can still have success in growing watermelon vines by starting seeds indoors. Watermelon seeds rank as one of the easiest seeds to collect and save from ripe fruit. You can start watermelon seeds indoors two or three weeks before they are to be set out in the garden. Don't start seeds any earlier, because large watermelon seedlings transplant poorly.
