in the garden there will be eight raised beds that each measure 5x10 feet in size. i'll be able to plant herbs, beets, greens, kales, broccoli, cabbage, beans, peas, onions, garlic, carrots, melon, cucumbers, squash, corn, radish, strawberries, tomatoes, and potatoes in each and every bed, all arranged with the shortest on the southern most part leading to the tallest and trellised on the north of each bed. there'll even be room for interplanting green manure plants like dandelions and burdock and comfrey.
so, if there are five heirloom vining tomato plants or five squash plants trellised up, i'm guessing that it could weigh as much as 100 pounds; 2x4 studs may be needed to frame it in. trellises for peas and beans need not be as strong, half inch bamboo lashed together with string will be fine. trellising for cukes should probably be somewhere in the middle in terms of strength.
i can vine grapes and cold hardy kiwis up the now-proposed arbor under the tree nearest the garden (i think i might have enough 2x6 lumber left to build the arbor. maybe i'll try to plant hops or something else up the trees. in 2009 i tried to run two kiwis up the tree along the driveway, but the squirrels trampled them down and they never took.
i'm getting some input and design ideas from a nice guy i met on the permies.com forums. he came over and took some photos. he's taken a permaculture design course. vince will be giving me some nice input hopefully. i'm certain there are things i'm just too inexperienced to know.
