. Florists' review [microform]. Floriculture. TROUBLE WITH GERANIUMS. 1 am sending several leaves of S. A. Nutt geranium. Can you tell me what the trouble is? This disease is spread- ing rapidly through about 7,000 of these plants. The leaves turn yellow and then dry up. I have been using sul- phur lately, as you can see by the leaves. I can not discern insects of any kind. Syringing with water has no effect. Any information you can give me will be greatly appreciated. G. A.

. Florists' review [microform]. Floriculture. TROUBLE WITH GERANIUMS. 1 am sending several leaves of S. A. Nutt geranium. Can you tell me what the trouble is? This disease is spread- ing rapidly through about 7,000 of these plants. The leaves turn yellow and then dry up. I have been using sul- phur lately, as you can see by the leaves. I can not discern insects of any kind. Syringing with water has no effect. Any information you can give me will be greatly appreciated. G. A. The leaves were much dried up when received and it is not easy to tell what your trouble is. Possible causes are unsuitable soil, injudicious watering and feeding, starvation at the roots and the excessive use of sulphur on heating pipes, either painted on or dry. The last named will quickly cause a lot of foliage to turn yellow. Feeding with heavy stimulants, such as nitrate of soda, unless carefully done, at fairly long intervals, also is harmful. The use of soil deficient in plant food would give the plants a starved look and the foliage would naturally soon turn yel- low. Sprinkling sulphur on the foliage will be of no avail. All you can do is to keep the plants growing along. Do not allow them to become too much pot- bound before giving a shift. Use a soil containing three-fourths loam and one-fourth well decomposed cow ma- nure, hotbed manure or mushroom ma- nure. Add a 4-inch pot of fine bone to each wheelbarrow-load of Spray of Lille* and Cattleyas Designed by Henry Hansen, Catskill, N. Y. Never keep the plants really wet at the root. Allow them to dry out fairly well between waterings. Do not spray overhead. Grow in a house with a win- ter and spring minimum temperature of 45 to 50 degrees. Ventilate freely and give them all possible sunshine and they should do well. Pick over your worst plants and feed judiciously where they may be needing it. You should soon note an improvement. C. W. THE WORK OF CATERPILLAR? The leaves on some of my geraniums are diseased, especially on Viaud.
