GEBANIUM FOUAGE CUBUNG. 



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. Quite a lot of the 

 lower leaves turn yellow. I have them 

 iu 21^-inch pots and some in 4-inch, 

 but they are all alike. I have not 

 sprayed or fumigated them at all. 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.

DISEASED GERANIUM I.EAVES. 



, I am troubled regarding my gerani- 

 'i^s. Recently they were attacked by 

 Sftme insects or a disease. 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 

 i I sects on them. I have painted one, 

 ' ' the pipes with sulphur, so that the 

 c ior of it can just bwt^tOBted on emk. 

 (ring the greenhouse. Is that too 

 irnch? The geraniums were affected 

 '" fore I used the sulphur and had only 

 ''■ on fumigated with tobacco. Any in- 

 ■Tmation you can give me will be 

 • -"atefully received. V. R. F. 



If well rooted in the pots, give them 

 a moderate stimulant once a week to 

 encourage them to make new growth. 

 For this purpose a teaspoonful of ni- 

 trate of soda in a 12-quart watering 

 pot is good. After using this twice, 

 a considerable improvement should be 

 detected. Your plants are similar to 

 many others at this season, but do not 

 be alarmed about them, as they will 

 eventually come out all right. Do not 

 let the plants stand too close together. 

 Pick off all dead and dying foliage. 

 Keep a pure atmosphere and a night 

 temperature of 48 to 50 degrees and 

 they should soon pick up. C. W. 



FUNGUS ON OEBANIUM FOLIAGE. 

 I send you a few geranium leaves 

 which are affected with a disease 

 which I would call fungus. If you know 

 anything about the disease, would you 

 kindly let me know what to do for it? 

 F. G. E. 



The leaives, which had almost 

 crumbled to pieces before they reached 

 me, had evidently been attacked by 

 some fungoid growth, which is not at 

 all uncommon at this season. The 

 best remedy is to pick over the plants 

 frequently, removing affected foliage; 



The foliage forwarded showed no 

 ~'i,'ns of any insects, but had the ap- 

 Harance of being attacked by bacteria. 

 Ibe sulphuring of the pipes would not 

 'jiuse this; in fact, it should, if any- 

 thing, help to^revent its spread. Pick 

 ^ff the wors«tffected leaves and give 

 ttie plants aj^pr^tfg' with Bordeaux 

 jnixture. Gife thlfei all the sun and 

 light possible. Ventilate the house 

 freely. Do not spray them overhead. 



spoonful to a 12-quart can, once a week 

 until they improve. Always avoid a 

 moist, close atmosphere, which would 

 aggravate fungoid troubles on gera- 

 niums. C. W.

 leaves. The leaves dry up aroAd the 

 edges and finally drop off. I would 

 like to find the cause of the trouble and 

 a remedy, as some of the plants are 

 entirely without leaves. H. G. 



Isolate the affected plants from those 

 which are apparently healthy. Give 

 all your plants a spraying with Bor- 

 deaux mixture; also keep them picked 

 over. Allow a little space between the 

 plants, and do hot syringe them over- 

 head. If the plants are well rooted in 

 the pots, feed them with soot or nitrate 

 of soda water once a week until they 

 show an improvement. A teaspoonful 

 of nitrate of soda to a 12-quart. can of 

 water will sufiice. Plenty of sun and 

 air and an average minimum tempera- 

 ture of 48 to 50 degrees will suit the 

 plants. The cause of the trouble can 

 only be conjectured, but with care you 

 can overcome it. C. W. 



HUEBNEE'S NEW ANTIBBHINUM. 



The photograph here reproduced 

 shows some vases of the new antirrhi- 

 num raised by H. Huebner, of Groton, 

 Mass. With reference to the origin of 

 the plant, Mr. Huebner states that 

 about twelve years ago he found an 

 antirrhinum seedling growing among 

 his violets outdoors. In housing the

also give them a spraying with '"Bor- 

 deaux mixture. Keep the plants some- 

 what on the dry side and do not 

 syringe overhead at all. Let them 

 have plenty of sunshine and fresh air.
