I have a feeling my title didn't quite explain what I'm trying to do. I want to dig a SHORT 1.5foot hole that is as wide as a trash bag, then cut the bottom of the trash bag and put it in the hole. This way, i can essentially get an extra 2 feet of hole depth, because the bag will be partially out of the ground. So a 1.5 foot hole + trash bagfilled with dirt stiking out = 3 foothole. Plus once the plant hits the bottom of the dug hole, it will start growing new roots into the hard clay soil. But that wont be a big deal because it will have 3 feet of root structure already. Do you guys like my idea? I saw it somewhere...
