Watermelons not fully ripenning
I am growing several varieties of watermelon in my S.E. Texas vegetable garden. The plants are growing wonderfully, and producing nice large melons. None of which ever fully ripen. Some of them were on the vine as long as 8 weeks before we picked them. The tendril and spoon were brown on most of them and the white bottom was a creamy yellow on all of them. Yet when we cut into them, they were white all of the way or almost all of the way through.
