This year was my 1st yr of SFG. I did 18 4'x4' beds. It was a great learning experience and the harvest (still going on) has been great! I've read a bit about trellises on the forum. I used bamboo, from along our creek, set inside 2" PVC pounded 1' into the ground, with 2' exposed. The bamboo got wet & withered. So I scabbed 1" pvc pipe to it & THAT bent over too! My tomatoes, 4 to a trellis, were just too much.
Will 3/4" thin-walled electrical conduit handle 4 tomato plants? I'm trying to keep costs down.
Thanks in advance.
