Long story short dug a pond used all the clay from it to mound up on some well rotted 3ft around logs. Seeded it with hairy vetch, red winter wheat, garlic bulbs and comfrey root cuttings in October I think..memory fuzzy and Im bad about writing things down. Chopped it today and seeded it with 4 different type of watermelon, calendula, radish, planted some gooseberry at the base, an Antonovka apple tree, strawberries. The whole thing was loaded with ants and worms and other critters and the clay was noticeably softer. The hairy vetch produced a lot of mulch. Will post more pics if the watermelon come up.
