This is my first posting!
After fighting scale with alcohol & cotton swaps for a year I am ready to give up. I have approx. 150 Cattleyas, but spend my time fighting scale and not enjoying my orchids.
I have purchased Bayer Advanced All In One Rose & Flower Care (concentrate, 32oz) and would like to dip all the pots in solutiuon. Could someone recommend a suitable mix ratio.
