I have an Iwan. Apple Blossom 'Golden Elf' that I've been treating for scale with a mix of cooking oil/soap/water. There are two new growths on the plant. They didn't seem to have damage from the scale, but I sprayed them anyway since the rest of the plant was infected. Anyway, some of the mixture seems to have lodged inside one of the new growths because now where the new leaf is emerging, it is black and papery thin. So my questions are:
1) How do I treat that area? Peroxide? Cinnamon? Cut it?
2) I'm supposed to spray the plant twice more for scale, but I'm guessing I should NOT spray that new growth?
Aargh. Right now I feel like my orchids would be happier without me.
Thanks in advance for your help.
