AMERICAN CARNATION SOCIETY. 



New Varieties Registered. 



The following new carnations liave 

 been registered with the American 

 Carnation Society by H. C. G. Schwarz, 

 of Central Park, N. Y.: 



Glow Worm: Seedling cross; brilliant red; 

 Mze tliree and ooe-half Inches; clean grower, 

 producing finest quality flowers the entire seii- 

 son; never splits the calyx. 



Keaolute: Seedling x Enchantress; pure white; 

 size, four inches; extremely prolific; flowers have 

 great substance; unusually long stem. 



Spring Olory: Pink Delight x seedling; size, 

 four inches; deep pink, verging on red in winter 

 and changing to rose pink with deeper center in 

 spring, 



Mrs. U. C. G. Schwarz: Pink Delight sport 

 X seedling; shell pink; size, four inches: ex- 

 ceptionally strong grower with wide foliage; 

 «-xtremely long, straight stems.

GROWING ENCHANTRESS. 



I am sending you a few stems of 

 Enchantress and White Enchantress. 

 They are making a strong growth, but 

 the leaves are getting light spots on 

 thcni. I also notice that some of the 

 lower leaves get brown or black later. 

 A few of the leaves have spots with ;i 

 kind of web on them. Kindly let me 

 know what this is, for this is the first 

 time I have grown carnations. 



A. L.— Mo. 



Those brown spots with the powdery 

 substance are the common carnation 

 rust. Pick off what you can and spray 

 tlioroughly with Bordeaux mixture. 

 Kee]) the plants dry overhead as mucli 

 as is practical. Water carefully, though 

 not sparingly, at the roots. Give abun- 

 dant ventilation on all favorable occa- 

 sions. l*aint one of the heating pipes 

 in each house with lime and sulj)hur in 

 «>(jual parts, mixed with water. Keeping 

 a dry, buoyant atmosphere will help the 

 ])lats to outgrow the disease. 



The light spots in the leaves are caused 

 by bacteriosis. Most varieties of carna- 

 tions are, in time, attacked by this dis 

 ease and sooner or later succumb to its 

 ravages. There has been much differ- 

 ence of opinion as to just what causes 

 this disease, the most commonly ac- 

 cepted theory being that it is caused 

 by the punctures of insects and poisons 

 entering at these punctures. The En- 

 chantress varieties have been in culti- 

 vation an unusually long period and 

 although they have shown the effects of 

 this disease in increasing quantity, they 

 are still doing well, showing a re- 

 markable degree of vitality. Careful 

 culture will assist greatly in reducing 

 the ravages of this disease, as is proved 

 by the varied amount of this disease on 

 different places. It might be said that 

 anything that will promote a soft growth 

 will aggravate the disease, while culture 

 which produces well matured leaf 

 growth will assist the plant in resisting 

 the disease. That means that you 

 should water carefully, allowing the soil 

 to dry out fairly well before each water- 



ing. Avoid fertilizers which are ex- 

 cessive in nitrogen. Give abundant 

 ventilation on favorable opportunities 

 and carry an even temperature. Later 

 on, when taking cuttings for propaga- 

 tion, avoid those plants showing these 

 light spots as far as possible. Keep the 

 young plants growing along steadily in 

 a cool, light position, which will help 

 to build up the vitalitv of your stock.

THRIPS SPOIL BUDS. 



I am sending you a few carnations. 

 What is the cause of their opening in the 

 manner shown, and how can I prevent 

 it? A. E.— Pa. 



have been lax in your spraying or 

 fumigating. You should spray or fumi- 

 gate regularly once each week, even 

 though you may not see any indication 

 of thrips or aphis. It is far easier to 

 keep them away than to get rid of them 

 after they have a foothold. Now that 

 you have them, apply the remedy two or 

 three times weekly until you have 

 cleaned them out. Do not increase the 

 strength of the doses, but repeat the 

 applications oftener. A. F. J. B. 



PEST IS SOW BUG. 



There is something wrong with our 

 carnations. The leaves are turning 

 brown and seem to dry up and are full 

 of holes. I found some small worms, 

 like angleworms, in one of the dead 

 plants. We found them in the soil 

 around the plants, too. What is the 

 best and quickest wav to get rid of 

 them? 'n. W. B.— la. 



Your carnation blooms are being in- 

 jured by thrips. These tiny insects 

 puncture the tissue of the petals while 

 they are still in the bud, causing these 

 white spots, which are really dead tissue. 

 Usually these spots are brown on the 

 bloom of light shades of color and white 

 iu the dark-colored varieties. The pres- 

 ence of these insects jjroves that you 



Your main trouble is probably with 

 sow bugs. Drop a pinch of Slug Shot 

 here and there on the edgeboards of your 

 benches. If you have none on hand, 

 take granulated sugar and mix enough 

 Paris green with it to make it deadly 

 and drop it along the edgeboard. It will 

 require considerable persistence to get 

 rid of this pest. A. F. J. B.

BLACK ROT OF GERANIUMS. 



Our geranium cuttings turn black and 

 rot over niglit. What is the cause? 

 We have tried Grape Dust. 



E. & S.— Mich. 



The name of the other plant is strcji 

 tocarpus, or cape primrose. M. P. 



Outdoor geranium cuttings do not, as 

 a rule, root as readily as those from 

 indoor-grown stock. The fall growth 

 is apt to be soft and, in the absence 

 of bottom heat, they damp off. Indoor- 

 grown cuttings have the advantage of 

 being better matured and can be left 

 on the plants until firing has commenced 

 and bottom heat has been provided.

GERANIUM DRYDEN. 



I am sending a geranium leaf and 

 flowers. Two years ago I discovered 

 just one plant of it. It is a quite slow 

 grower, but a good one. Can you tell me 

 the name of it? C. E. S. — O. 



The flower of the geranium arrived 

 badly crushed, making it difiBcult to tell 

 its name, but I believe it to be the 

 variety Dryden. M. P. 



VARIEGATED GERANIUM. 



We are sending you two plants. Would 

 you kindly tell us their names? One 

 is a geranium we have grown for sev- 

 eral years. Our first plant was given 

 us under the name of the Kansas ger- 

 anium. It has proved a good, strong 

 grower, with bloom much like the 

 General Grant. The leaves are usually 

 mottled with white and are sometimes 

 entirely white. It is a good seller, as 

 the foliage is handsome. 



E. W.— Kan. 



The geranium is unknown to me. I 

 have seen the same variegation among 

 the standard varieties, but do not con- 

 sider it of any great value. 



GERANIUM CUTTINGS ROTTING. 



Please tell me why my geranium cut 

 tings rot and turn black in the sand 

 boxes. I am having a great deal of 

 trouble in that way. I have to throw 

 out whole boxes. S. L. J. — 111. 



The trouble is due to weather con 

 ditions and to the fact that the cuttings 

 were too soft when taken. The trouble 

 generally happens to cuttings taken 

 from the field in August and early Sep- 

 tember. Those taken later in September 

 or early in October are harder and do 

 not suffer so badly. Care in watering 

 is desirable in order not to get the sand 

 too wet. Water only to prevent the 

 cuttings from wilting. M. P.
