Late Winter/Early Spring is a great time for planting, (not just bamboo but many trees and shrubs). This is because you have the great combination of cool and moist conditions and warming soil . This means plants establish quicker and need less help from you doing so.
This nice little planting window will last to late March normally. We have some lovely bamboo plants for sale at the moment and as always if you're not sure what to put where please do get in touch.
