Depending on the variety, watermelons are meant to be grown in the ground, not in containers.

I don't grow watermelons due to my little garden (small yard) but really sad to hear the local produce stand near me is going out of business next year. He was my last source for Yellow Doll watermelons. We sure enjoy this variety as early and mighty tasty.

Yes there are other produce stands near me but all now grow and offer those awful seedless watermelons (spongy texture). I cannot find seeded melons for sale anywhere. Kudos to all you home growers who have the room and grow seeded watermelons. I am envious!

Ray-I get that but it's not an option now. The varitiey is Crimson sweet.

Spartan-seeded watermelons are only for the home gardener these days.

If you water every day you should get some melons. I'd expect them to be on the small side. You'll also need to add nitrogen about once a week, maybe more.

I'd stand the fabric pot in a shallow saucer. That helps to rewet the mix if it gets too dry.
