I really did not think I would even get any watermelons this year, since it’s been such a cool, strange and short summer – but I decided to put them in an earthbox this year, placed on the concrete in my side yard, figuring that way they would get maximum heat.
The side yard gets lots of sun, and the concrete gets hot and creates a little micro-climate of perfect growing conditions.
So, the other day I harvested my first watermelon of the year, and it wasn’t bad!
