What can I soak a sick plant in for serious scale?
I have a small cymbidium which I am quite keen to rescue but it keeps getting worse. It has an extremely bad scale infestation which has got right into all the gaps between the leaves. I have manually removed a lot of them and been spraying it with a pesticide to try to get rid of them but to no avail. The plant has continued to decline.
Is there anything else that I could soak the whole plant in that might help? Is it worth soaking it in peroxide or something like that?
