Ami,
Yep, hard to believe that this new smaller wicking basket keeps 3.3 cubic feet of potting mix quite moist. I never would have believed it - - but here is proof positive of a Purple Haze planted in early August, and is now doing well into November in its EarthTainer II design:
The wicking action permeates through the landscape fabric just fine, and my goal is to contain the root system from growing down into the water reservoir.
