Fall made hugel zone 6a/b.

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.

Wow! I think you will be surprised at the extent of the watermelon. You have tanked that thing up, I would not be surprised if you have watermelon all over the extent of the last picture! I really like Hairy Vetch. Save some seeds if you haven't! Great early flowers for bees.

Yah we grew black mountain watermelon last year and they grew well..this year I've added some golden midgets and cream of saskatchewan's. Hoping they cross and make something interesting. I was amazed at how much green stuff the vetch made. A few flowered out but I didn't wanna wait much longer to chop it..have some in the back area though that I'll let flower. I still have some seed left in the refrigerator for this fall. The Hugel is bigger than what it looks as well. I was about 10 foot up in the air for the photo.
