Can you truly get rid of scales
My plants have what I believe are scales. It seems I have lost several plants to them over the last few years. They seems to infest a plant, sometimes I get them under control temporarily and they seem to move onto a new plants or sometimes they just kill that plant. They truly suck the life out of them.
Is there any way to really get rid of these once and for all. I have tried soap and water, I have bought insectides. I have two right now I am trying to save. Maybe I should just throw the plants out. That's so hard, as they were big beautiful plants at one time.
