late season watermelons

At the insistence of my girls, we are planting watermelons, although they will come a *wee* bit late in the season. Tried one mound, planted six seeds, spaced three inches apart in two rows.

Mixed jungle growth and black kow into the Georgia clay, tried to do equal parts. Also, put down a layer of pure black soil at the top, with some potting soil mixed in, although this was largely by accident, as I had transplanted the mint to a bigger pot and some of the potting soil ended up on the ground and in the hole.
