I'm already using polycultures, but not come across keyhole beds before. Will try one or two in the new garden I'm building.
Also just starting with growing bamboo, so hopefully I'll have some of my own bamboo next year (although not sure yet how fast it grows).
Where are you located that you started growing bamboo? Just curious because I have heard it grows in many places in the US but not sure if it would grow in my zone
I'm in Wales in the UK. A friend of mine nearby has a variety that grows prolifically here, he's giving me some to start.
