Moth Orchid -very sickly
I have been growing these lovely plants in my bathroom, successfully for 6years now. Recently I have been given another-set in the usual transparent plastic pot with bark compost but it has been sitting in a copper trough, I wonder if the copper may be causing the sickness? As a precaution I have placed it in a pottery cover, after a fortnight it is no worse but neither are there any signs of recovery. Any advice please?
