I've just cut down some rogue bamboo which was sprouting from an otherwise orderly bamboo screen. Just over 2 weeks ago I noticed some rather thicker canes emerging from the ground. In the sixteen days since they've grown to anything from 8 to 20 feet tall, spoiling the look. So I've just spent a very satisfying hour sawing the buggers down, then into smaller pieces and chucked the lot in the recycling. :)
Just hope they don't grow back.
