Re: Is this brown scale?

Hi, Chris,
It sounds like aphids (though strange to have them if this plant is indoors). Aphids secrete a substance called honeydew - a sticky solution that once it drops on the plant's leaves, can encourage the growth of sooty mould - most likely the black spots you see. Too things are probably causing the leaves to droop. First, the abrupt change from inside to cool, night conditions will shock the plant. When moving an indoor plant outside, it needs to be acclimated slowly. Since Murraya is tender, it might not like the colder temps, especially at night. Second, the spray might have been too strong. Sometimes, you can remove many aphids by spraying them off with a hosepipe. Is it still outside? Any chance it is getting to cold?
