16 Jul 20, Jodie (USA - Zone 9b climate): My grandkids want to grow watermelon with the seeds from a fresh watermelon. It's mid July and we're in zone 9b in the Arizona desert. Thank you in advance. Happy planting!

23 Jul 20, colleen (USA - Zone 10b climate): Fun project! Be aware that seeds might be sterile from a store-bought melon (and likely won't be true to seed). But worth a shot for the surprise factor, I think. They should try the paper towel sprouting method to test viability. If seeds sprout, get them in the ground by August and there should still be time for fruits. They'll need plenty of water in hot weather (mulch helps too).

05 Jan 19, Petra (USA - Zone 9a climate): Watermelon like all other melons, squash (incl. zucchinis) and pumpkins produce both male and female flowers. So only one is needed. However i always plant two or more in case one fizzles out.
