Invasive triffid-like bamboo
A metal fence and a concrete path seperate my greenhouse from an ever advancing bamboo. Sold as a dwarf variety, its cuckoo tendancies soon came to light when the main clump grew approx 6m tall, however I was taken in by the way it swayed so elegantly in the breeze and it stayed.
Now behaving like a rioting teenager the bamboo is causing grief & destruction and I have no idea how to control it. We've all had a hack & thrown weedkiller at it but instead of taking the hint my efforts have only seem to have encouraged it to do a bit of travelling, its latest journey through the cracks in the concrete path and into the green house where its already hitting the roof. The green house is large, made of wood, has a soil base, and on its last legs but I can't afford to replace it. Any suggestions???
