I have used the lasagne or sheet composting method to make several large garden beds. First, mow the grass down as low as possible, leaving the grass clippings in place. Lay down a layer of cardboard over the sod, and be sure to overlap the cardboard well or grass/weeds can grow through cracks. Then alternate layers of greens/browns, as little 1 or 2 layers (2" or so) or as many layers as you have available. Then wait. Some people say you can plant immediately, but I would only do so if you dig the planting holes well through the layers and sod and into the soil below so the roots of the plants can connect solidly with the soil. This method works extremely well, but it is slow. I have a couple of lasagne beds that were created in fall 2007. The organic matter has by now completely broken down and the soil is incredible. The plants are growing like gangbusters!

OK Tim, below are some of the questions I addressed from Leslie in LA. Leslie,mowing and weed eating the new shoots works best for us. We control our 153 species by doing this and have do so for many years. The bamboo rhizomes will grow in several directions underground looking for energy and sun light. When the rhizome buds are aborted ( mowed or kicked) and prevented from their energy and sunlight mission that rhizome will slowly die over a period of several years. In other words the root will grow outward and put up shoots or canes. When all these are mowed for up to three years that rhizome will die back to the point of the last cane that is supplying energy to it. Bamboo is a grass and persistent, but not magical. It will grow where you let it and there are proven ways to control it very easy. The Japanese and Chinese have lived and loved bamboo for thousands of years. They grow it on thousands of acres and in small 100 square foot court yards. You should visit a bamboo farm and see first hand how bamboo grows and there are several down your way. Moso does grow to over 70 feet as there are mature groves of Moso on Avery Island, Abbeville and several other cities in LA. Any knowledgeable bamboo grower knows the huge Moso that grows through out the southeast including LA. The Moso growing in LA is second only to the Fant clone of Moso that started it all in Anderson, S.C. This clone can be seen at: ANDERSON GROVES DIRECTIONS Directions: Take exit 19 off I85 towards Anderson (US 76, US 25 and Clemson Blvd.) in about 7 miles Clemson Blvd. changes to N. Main Street. Two blocks past city hall, turn left on E. River Street. Turn right on White Street, at the forth traffic light. The entrance to Silverbrook cemetery is two blocks after you turn on to White Street. The bamboo maintained by the SEC is located at the back of the cemetery. I am sure you know where Avery Island is and it would be a great site to visit and see large Moso. Roger Sr. I have two more questions. Your website suggests controlling bamboo by mowing, or by kicking over the newly emerging canes. I like this idea - it may work well for me. But I'm confused. If I mow/kick over canes in a 30-foot zone around my grove, wouldn't the rhizomes eventually continue travelling underground (past the kicked-over/mowed culms) until they got beyond the 30-foot zone (and into my neighbor's yard)? Second question: I really like the moso bamboo. Does it really grow to 75' in the southeast? (I live in zone 8, south Louisiana). One website said the average height in the southeast is 30 feet -which would actually be better for me, where I'd like to put it. (I have hard, dry clay soil.)

Phyllostachys aurea or golden bamboo may actually work that way, even though it's a horrible time of the year to take rhizome divisions since it is known to be a species that is good at generating small survival shoots. It is also known to be one of the most aggressive species especially if you are in a warmer climate so before getting it into the ground, make sure you have an effective plan of action to keep it contained so shoots don't come up all over your neighbor's yard if you are screening them out.

I have dug 100's of bamboo up by hand, and can see that you have quite a big task there, and one I would only attempt with heavy duty machinery. I've seen stump grinders at work, but never used them on bamboo. When I had two big clumps of black bamboo die on me, my friend with the big backhoe took them out. He was surprised at how tenacious the rhizomes were and how hard the backhoe had to work to get them out. In your situation, and given the huge mass of rhizomes you want to remove, it may be easier to eliminate them with the stump grinder, although I can't tell you that for sure. If you could only get a small backhoe into that area, you might not be able to make much progress.
