603 



House of Bridesmaids at the Establistunent of Poehlmann Bros. Co.i Morton Grove, IlL 



era and in graperies, it occurred to me 

 that it might be of benefit to the growing 

 of carnations. After a trial on a small 

 scale the result is that rust is absent 

 except in two new varieties purchased 

 last spring. Other ailments have also 

 been less prevalent; in fact, our plants 

 have improved from year to year. 



I do not claim that this is altogether 

 owing to the use of Grape Dust, but it 

 has been an important factor in dispel- 

 ling fungus disease and to my mind it 

 has aided in stamping out rust. Apply 

 at intervals of two or three weeks when 

 the plants are dry, at the time of day 

 when the houses are the warmest. If 

 possible choose a bright day following 

 one in which you have watered. By this 

 means the preparation is allowed ample 

 time to extend its influence before an- 

 other watering. 



A thorough spraying with Bordeaxrx 

 mixture twice during October will great- 

 ly assist in keeping the foliage healthy, 

 and as the leaves of a plant are its lungs, 

 it is evident that this is an important 

 operation. Use a spray pump arranged 

 with a nozzle capable of making a fog 

 enveloping the whole plant. As this is a 

 liquid, apply early in the morning of a 

 bright day, choosing a time as before 

 mentioned regarding Grape Dust. Your 

 judgment will tell j'ou to plan the opera- 

 tions to occur by alternation. 



It is a good plan to paint some of your 

 pipe with a mixture of lime and sulphur 

 as soon as firing is begun. You must 

 decide as to the amount of surface to be 

 ■covered, for when steam is used less will 

 answer than when hot water is employed, 

 the object being to diffuse a faint odor of 

 sulphur through the house. Slake the 

 lime in hot water, adding the sulphur as 

 fioon as violent boiling ceases; stir thor- 

 oughly until mixed and apply at once. 

 We use one pound of sulphur to four gal- 

 lons of wash, allowing the mixture when 

 done to be somewhat thicker than ordi- 

 nary whitewash. 



See to it that the space under the 

 benches are free from rubbish, such as 

 decayed wood, dried leaves, broken pots, 

 etc., which if allowed to remain are sure 

 to harbor insect pests as well as become 



a breeding ground ft^ fungous diseases. 

 Give the ground under the benches a gen- 

 erous coat of air-slaked lime. 



It is wrong conditions that produce all 

 ills the human flesh is heir to and so it 

 is with plants. People often say: "I 

 don't have any luck with plants." Neither 

 do successful carnation growers. The se- 

 cret is their ability to produce proper 

 conditions suitable to the growth of that 

 particular plant, and when those condi- 

 tions have been brought about it will not 

 be a question of selling the product, but 

 rather who will get it. 



Pardon the slight digression, but I feel 

 that prevention of disease is not prac- 

 ticed to the extent it should be, espe- 

 cially when our hybridizers are putting 

 forth every effort at present to produce 

 healthy, fine blooded stock, which of 

 necessity must be kept healthy to remain 

 in the class to which it belongs. 



Not being a believer in the coddling of 

 plants, or classing myself as a plant doc- 

 tor, but preferring rather to associate 

 with healthy life of either high or low 

 order, prevention is everything.

CARNATION NOTES— WEST. 



If you find any blooms that show signs 

 of thrips in your carnation houses you 

 should lose no time in getting after them 

 in earnest. They can not stand the 

 fumes of tobacco, but the regular fumi- 

 gating once each week will not suffice to 

 destroy them after they have a foothold 

 and so you must get after them in a 

 more effective manner. If you began 

 fumigating regularly as soon as your 

 plants had taken a good hold your 

 houses will be tolerably free from these 

 parasites, but so many growers don't see 

 why they should fumigate their houses 

 unless they can see a lot of greenfly all 

 over the plants. Greenfly seldom seems 

 to bother us until well along toward 

 winter, but the destructive little thrips 

 remain with us the year round and need 

 attention at almost any time. You will 

 readily see the results of his work by the 

 white spots in your pink and red blooms 

 and the brown spots in your white ones. 



I do not know whether the various 



tobacco preparations will kill thrips or 

 not, but I do know that the smoke from 

 tobacco stems, or dust will do the work, 

 and that a tablespoonful of cayenne pep- 

 per sprinkled over the tobacco will help 

 to make it more ett'ective. Pick all the 

 blooms before you fumigate, and as soon 

 as you are through give all the air you 

 can so as to get rid of the smell as soon 

 as possible. Carnations will take up 

 the tobacco odor and hold it for a day 

 or two and so you can not fumigate every 

 day if you want to have salable blooms, 

 but by picking the blooms just before 

 you fumigate you can fumigate every 

 other day. Keep it up until you are sure 

 you are rid of the pest and then by 

 fumigating regularly once each week you 

 can keep your plants free from them.

GENISTAS AND ADIANTUMS. 



M. W. B. says his genistas are losing 

 their foliage after turning yellow and 

 that his "maidenhair" ferns are dying, 

 and would like to know what he has or 

 has not done. He says he has kept all 

 his ferns wet .and may have wet the 

 foliage of the "maidenhairs." 



Supposing the genistas to be canarien- 

 sis or racemosus, they are an easy plant 

 to grow. They do not make much growth 

 in the hot months. Most of their gro\vth 

 is made in the early spring, fall and win- 

 ter. Never plant them out. One-year- 

 old plants we sometimes plunge in a 

 frame during summer. Winter propa- 

 gated plants we like to grow indoors dur- 

 ing summer. In the hot weather they 

 should be often syringed, for they are 

 ever ready to be attacked by red spider, 

 and this I think is the trouble with 

 M. W. B.'s plants. When winter sets in 

 they want a cool house; 45 degrees at 

 night is about right. 



It is quite difficult to say what is the 

 mattermth the "maideniiair" ferns. They 

 should never want syringing; still, in 

 warm weather an occasional syringing 

 should do them little harm. They want 

 a moderate amount of water, about as 

 the great majority of plants do. 



Slugs are their great enemy, and air- 

 slaked quick lime dusted over the fronds 

 and on the crown of the plants is the 

 best and most effective remedy. With 

 ordinary treatment the fronds of "maid- 

 enhair" ferns should not turn brown till 

 they ripen with age, except from one 

 cause, and that is tobacco smoke. It is 

 just possible that M. W. B. has been 

 fumigating the house containing the 

 ferns. Great cure-all that tobacco smoke 

 is. it very quickly browns and shrivels 

 up adiantum fronds.

AILANTHUS GLANDULOSA. 



I enclose sample of foliage and seed 

 of a tree which I wish you would give 

 the name of in the Review. Also the 

 best way to grow it from seed. Is it a 

 good tree for shade and as an orna- 

 mental tree for parks? Subsceibee. 



Tlie tree is Ailanthus glandulosa 

 (Desf.), called "Tree of Heaven," intro- 

 duced some years ago from China. It 

 is fairly hardy in this region though 

 exceptionally severe winters in some 

 places kill many of the older trees. 



It is of rapid growth and fine ap- 

 pearance and does well in cities as an 

 ornamental and shade tree, reaching 30 

 to 35 feet, with an open, airy head. Some 

 of the trees bear seed and others have
