My plants look deformed, especially in the center. Leaves are distorted and brittle, flower stems stunted. What is causing the trouble? I can’t see anything on the plants.
The problem is probably cyclamen mites, which are invisible without a magnifying glass. They attack a number of plants besides cyclamens, especially African violets. Badly infested plants should be destroyed. Others can be sprayed frequently with malathion. But to put a permanent end to mites—or at least to stop them for a long time—treat your plants with sodium selenate.
