Bamboo Fence Panels Bamboo Fence?

Bamboo Fence? - bamboo fence panels

I bought) a role Bamboo 7 "high x 8" wide (1 "diameter. I have the right support - Pre holes, etc. The problem is that they do not get to the original panel and bamboo cracks. No cracks, where the screws went and I am so frustrated. I expect to have to replace in 5-7 years but not more than 4 months old.

I am desperate for help. Do I get some bamboo bad? Hopefully bamboo iron worked better?
