I've read how neem oil can be sprayed on new plants (3 times/a week apart) as a preventative measure against disease/pests. I've never used neem oil and was wondering:
a) How frequently should it be sprayed as a preventative on 'established' plants? Each time I repot?
b) Has anyone's violets experienced adverse effects with neem oil? Can the leaves breathe through all that glossy oil?
I would conduct a trial on a leaf or two but on my micros a leaf or two is a good chunk of the plant and I'm afraid I might kill them. Thanks a million in advance for your input!
