Poinsetta damage - leaves
I had two big poinsettas on the deck all summer. One of them I've had three years, the other only since last Christmas. Now that I have them indoors they are shedding leaves. The leaves curl, change color and then fall off. The spine of the damaged leaves have what look like little sand grains. Egg cases I would assume. Anyone who can give me an idea about what is causing the damage and a methodolgy for dealing with it, I'd be grateful. These two poinsettas will have red leaves by Christmas if I can keep them out of trouble.
