On Calvin's birthday we decided it would a good time to harvest one of his melons.
I gave him a knife and he cut it off the vine. It was HEAVY!!! The thing had to weigh at least 20 pounds!
Alas, it was NOT RIPE!!! Calvin was so let down, I thought he was going to lose it right there (he didn't). I don't know how to tell when watermelons are ready -- do you? We thumped it and it sounded like the ones you buy in the store. We have two more on the vine, though one looks like it's dying. So I think we have one more shot at having a home grown watermelon. Please, any advice on how to tell when it'll be ready is greatly appreciated.
Next year we'll try and find a smaller variety.
