i had been mocking up a few ideas from a t trellis to a vertical one for my hardy kiwis. my span is only 20’ and its my first go at it so i went with the cheapest solution and did a vertical one with t posts and 2x4s:
its using 10’ 2x4s for bracing at the top and 8’ t posts set 2’ in ground. was going to use chain link fence materials but that would significantly increase the cost. completely underestimated drilling holes in the t posts. take it slow and chip away at it. literally bit by bit
