I'll look into those suggestions...I've asked a plant guy before, and he just giggled. Pretty much said to learn to live with it.
Maybe it will get big enough, we can build a treehouse and be the new generation of Swiss Family Robinson.
I empathize. I am currently waging a losing battle against daylilies--the only way to get rid of 'em is to dig 'em up. In one patch of lilies, about 24 square feet, I dug up well over ten thousand bulbs. The bulbs have packed in so tight, it is like digging through concrete.
And I only have about 400 square feet left to go through!
