Re: Grape trellis frustration
Can I just build two T shaped structures with 4 X 4's (securely planted in concrete), at 6 feet apart, about 4 feet tall with 12 gauge wire stretched between from each end of the T, letting a main grape 'trunk' grow up to the wire and then out to each side along the wire, with Canadice and Himrod grapes hannging down? Or will I need a second, higher wire?
Treated 4x4 posts might last you 10 years before they rot enough to replace. I know a guy that replaces his on that rotation schedule, even though he buys treated lumber every time. He talks about it like its a pain in the @$$.
I used Home Depot 8 foot galv fencing posts (metal) in cement. Also used their galv top-rail system for chain-link fencing for overhead, then place galv cattle panels over that. Been in place 10 years now, not a bit of rot or rust anywhere. Should be good for another hundred years!
And you can plant your grapes now, and take a year or two to get your structure up. No need to hurry unless you are compulsive about getting things done!
If your ground is deep and rich, maybe plant every 16 feet apart (the exact length of one cattle panel). If your ground is poorer, maybe plant 8 feet apart -- that way you can get two plants per cattle panel, if you choose to go that route.
