While googling around, (one of my favorite geeky pastimes) I found this:
"The second was simply to plunge
a stick into the ground an inch or so from the plant to a depth of about 3
inches - small diameter stick of about 1/4-1/3 inch. the result is that the
plant sprouts new "heads" near the holes within a month or two."
Has anyone ever tried this before? I have heard of plants growing out drain holes before, I guess the same concept. The roots pretty grow straight down, so i would thin there would be little chance of damaging them. I'll try it out today and report back.
