yeah i have seen drawings but never seen it done . .
the way ive seen it drawn is lst.. but to bend the plant over and then pin it to the pots edge all the way around and tie it down each time it grows.. to make a circle ..
I imagine you can grow it anyways you want... it is a weed. I have a friend whos trying to grow out of a topsy turvy hanging pot. growing it upside down. post some pics so we can see your progress.
