I am sending you some geranium leaves and should like to know what causes them to curl under as they do. The top leaves do not open out straight, but curl under.

Last spring I had a lot on which the bud only got about as big as a good sized pea and then would dry up and drop off. G. H. P. The plants have probably been much potbound or may have been kept too long in the cutting bench before pot- ting. Spraying or fumigating would not be likely to cause the trouble in any way. Aphis does not usually attack the zonale geraniums, but it does occasionally, and a fumigation or spraying with nicotine would then be necessary. A suitable potting soil is one containing good pasture loam, with some spent mushroom manure or old, decayed cow manure added. Some fine bone is also excellent; use a pot to each bushel of soil. Never use any fresh manure; it always produces a rank, soft growth. You do not state how warm you are keeping your gera- niums. They like 48 to 50 degrees at night, with all possible sun and a com- paratively dry atmosphere. Never let them get potbound, but feed occasion- ally when they show such a tendency. C. W.

The older leav^S"'<r9f s^jow tiny spots on the un- der side, which to the naked eye almost look Hke little welts. Soon the leaf begins to turn yellow and the under side looks as though the tissue had been punctured. The surface sometimes hns tiny red spots. The leaf turns yel- low at the edge first. The plants have been kept on the dry side and in a cool liouse and I am not able to find any iI sects on them. I have painted one, ' '
