Two or three years ago I planted to bamboo plants near a swampy spot on my property. Five feet away is tons of cattails. I worked the soil a bit. Planted the bamboo. Mulched with a couple inches of hay and then sat back to think about 30 foot tall bamboo that I would harvest and make stuff out of. Both plants now look about exactly the same size as when I planted them. They still have leaves. Although I would prefer the leaves would be a darker green this time of year. Does bamboo have special needs?
