Cu in fertilizer

bromadams(10b)November 23, 2008

Does anybody think that the bit of copper/CU that is in many fertilizers is going to have a negative effect on a bromeliad? The orchid fertilizer that I've been using does have a trace.

Does anybody have any pictures of bromeliads suffering from copper poisoning?

I believe that products for orchids and tillandsias contain something like 0.05% CU while anything above 0.10% is considered iffy depending on the frequency of use.

Yes, 0.05% is what my orchid fertilizer has. I did just buy some Shultz liquid fertilizer that doesn't list any.
