It's pretty hard to damage bamboo, short of preventing it from getting any water. Almost any fertilizer will work just fine with bamboo. I use Osmocote controlled release fertilizer, others use standard grass fertilizer, and I'm sure that fully composted chicken manure will not be a problem.

For my smaller bamboos that I am trying to upsize faster, I use fresh chicken manure, and it doesn't burn them at all. It just makes them turn greener, and more vigorous.

Thanks guys! I appreciate the advice. EB Stone Chicken Manure it is then.

Like Steve, and against all conventional fertilizer wisdom, I load heaps of fresh chicken manure all around my bamboo plantings. Has never fried any of them like people say it would. In fact, not only do I dump bucket fulls of it around the base, but my chickens also hang out under the boo and make additional contributions.

Hi. It's just the fresh chicken manure that burns the root system. Usually chicken manure is stored for a short while before it's sold to avoid this.

Thought this would be useful info on fertilising Buddha belly:

"Giant Buddha Belly Bamboo should not be given much nutrient at all, it will grow too fast to attain its distinctive swollen shape. But. if the leaves yellow then… better feed it something"
