I have a clump of bamboo which is twenty feet tall, width is 4 feet by
8 feet. It was grown to provide shadow over a lily and fish pond. It
has performed very well. However, keeping it from spreading has
always been a problem. This did not matter a great deal because
I had a field on three sides, the horses and cows did a great job in
keeping it cropped. All good things come to an end and a new housing
development is about to start in the afore said field. The survey team
drew my attention to 8 root runs each putting up from 5 to 9 clumps of
well cropped bamboo shoots. This according to the team leader is no
problem because they will be taking off about 4 to 5 feet of soil.

My problem is this. I will have to prevent further wanderings in the
future. I'm sure not many of the new owners will share my enthusiasm
for bamboo. What effective measures can I take, which will not harm
my bamboo and be low in maintenance? Anyone any experience?

Get rid of it and plant a clump forming bamboo, or you will be
fighting it for ever. They grow very quickly. Phylostachys is not
invasive in my experience.
