Oncidium twinkle leaves with spotting

[estación seca]

Horticultural oil will suffocate plants as well if used too often. It's hard to give a maximum frequency, but small thin-leafed plants will be much more susceptible.

I don't use oil much because I have good results with soapy water and alcohol. However, I mail ordered a Passiflora two years ago and it came with a type of scale I hadn't seen, Florida citrus scale. This is reported to be susceptible to neem oil. Online reading about treating passion flowers suggested not to use oil more than twice in a month.
