We have a row of Gracilis planted up two fence lines surrounding our pool. They were growing fantastically over the last year or so, then just one plant on the back fence started to look a little sad and the trunks blackened. We asked the bamboo place we brought them from and they said they're not sure, but to use confidor spray and tablets, so we did. It didn't seem to help. Now, over the course of the last month, the problem has spread rapidly to about 8 other plants and not just the ones beside the one that originally had the problem. I have no idea what to do, so I'm here hoping some of you bamboo experts can help save them Pics attached.

What's on the other side of the fence? Possible that the neighbors are doing something to the soil or spraying something? Some people are paranoid about bamboo...

Hi there,
I have a row of Gracilis along the sie of my pool and it is starting to look exactly like the photos minimatt posted.
I am presuming the cause is something to do with the chemistry of the pool water 'poisoning' the plants. But does anyone know whether it is chlorine, salt, ph, hardness etc that would be the cause? or too soggy? It is definitely not the neighbours!
Any help would be appreciated.

Cheers
James
