This maybe the most important post on this page and it's to do with.... Watering!
Watering your newly planted bamboo is essential for healthy new growth, as we move (i say hopefully) in to warmer drier months. For bamboo to have dense lush growth you must water regularly for the first few months to help the bamboo establish.
For bamboo in pots this is even more important and remains essential throughout the warmer months year on year.
It's very hard to over-water bamboo so if in doubt water!
