Bamboo should be sold with a warning!

We strongly believe garden centres and plant nurseries should place written warnings on bamboo to highlight its invasive nature and educate customers on the risks of planting it in their gardens. We have been delighted to see some interest from the press over the last couple of weeks, covering stories about the dangers of planting bamboo, and we are glad we got to help by sharing valuable information with the public, which we hope will help raise awareness nationwide.
