Guadua Bamboo Planting Layout

Guadua Bamboo Planting Layout

I am planning my mini Guadua farm on a half acre and some things I need to know are: If you start with 25gal pots of Guadua, how much distance should you space them apart? What is the estimated diameter of the clump after 5 years, and is there an average number of culms that come up each year or am I right to expect that the number of culms will increase each year?
