JBSF, twice each year I had an extremely bloody fight with that bamboo cluster, and that was just to keep it manageable. It was getting bigger each year, so the fights got longer. I was tired of it.
The bulldozer broke it into three pieces and I used the backhoe to drag them out into the field, far from water, to die.
They're about 40' high now. Sigh. At least they aren't on my property any more.
Bamboo looks great but it is impossible. They have passed laws in many of the towns on Long Island against planting any bamboo that is not properly contained and, I believe, makes the property owner liable for any encroachment onto other people's property. Having dealt with my neighbor's bamboo creeping onto mine for years I can attest that it is a losing battle to try to fight the stuff.
