Hi Mike,
Thanks for the kind words. One or two more fruits just emerged on the largest zucchini plant, but they still have a bit to go before eating. I will have to figure out what to make with them. I might try fries.
Yes, you are right about the paw paws, at least from what I have read and seen. My understanding is Southeastern WI is the border, but I have heard of a guy doing them further North. In this link
Yes, you have a great sense of direction, even with my disorienting camera work. Hah! The paw paws are on the north end toward the northwest corner. The mulberry cultivar (Illinois Everbearing) grows between fifteen and twenty feet. It is shorter than the Cornelian cherry redstone fruiting dogwood, which grows north of it and should reach twenty feet. Both of these trees are west of the paw paws. Since the paw paws prefer to be understory trees and they will still get considerable a.m. direct sunlight from the rising sun in the east and the mid-day sun in the south, they should be okay. The two paw paws that are furthest west might eventually get shaded out from the south by an extra long lateral branch from the Cherry or Mulberry, but I can always trim those branches if need be.
Thanks for sharing the images of your raspberries and strawberries; it definitely looks like they have filled out the space provided to them! I gave my raspberries a little room to run, but I will definitely be vigilante and rein them in when they begin running elsewhere. The runners will be relocated to a community garden or sold at a farmers market. Any remaining survivors will be composted. I'm thinking my strawberries will serve as a ground cover understory, so I am hoping they spread out like yours. It would be great to harvest them every few days like you are. I'll have to see what your chokeberry looks like this time next year, because I just planted a Nero Aronia a few weeks back as a bare root. It budded and flowered within just a few weeks, which was incredible to see. I don't expect it to produce fruit next year, but I'm hoping it continues to establish itself along the edge of the hugelkulture. Thanks for the feedback and happy growing!
