The Weekly Florists^ Review* 



August -IH. 1S»0- 



(langer of rust from it. The plants 

 have not had a great deal of water in 

 the field and I want to know whether it 

 will be wise to syringe them in the 

 same manner when I bring my outside 

 stock in. 



Of course our conditions here are some- 

 what different from the eastern growers, 

 and one must know them to be able to 

 form a really correct opinion, but I 

 think one familiar with carnations would 

 be able to give some points of value. 



I would like to have Mr. Baur's opin- 

 ion. COL0E.\D0. 



At this time of the year, while the 

 days are quite hot and the sun so bright. 

 I do not think any serious harm would 

 result fi-om a daily syringing about 2 

 o'clock in the afternoon. If plenty of 

 ventilation is kept on tlie houses and 

 the plants get the full sun the growth is 

 not apt to become very soft, and I believe 

 that on extremely hot days it can not 

 help being a benefit to the plants to give 

 them a light spraying overhead and to 

 kecri t)ie walks dnnr. d;irii'g mid-day. 



With as fine growing weather as 1 

 understand they have in Colorado's neigh" 

 borhood there ought to be very little 

 danger from oversoftiiess. It is during 

 the cloudy weather we luive during late 

 fail and early winter that we experience 

 the greatest trouble in Keeping our car- 

 nations from growing soft and too rank. 



If (Jolorado has not housed liis carna- 

 tions from the field yet lie ought to lose 

 no time in getting at it. They will need 

 syringing and close watching for a couple 

 of weeks, but as soon as they catch a 

 good hold I would cease the syringing 

 altogether except what they get in the 

 morning in being watered, an<I I would 

 also cease syringing the other.s, that were 

 planted some time ago, after about Sept. 

 1st. During that month the nights are 

 so cool and bracing and the weather in 

 general so favorable to the growth of 

 plants that nothing in the way of encour- 

 agement is required outside of plenty of 

 water at the roots, plenty of ventilation 

 and sunshine, with enough syringing to 

 keep down red spider, which may possibly 

 have been brought in from the field.

But under no circumstances should the 

 plants be wet over night, especially when 

 the nights are cool. 



We make a practice of going over our 

 benches early in the afternoon and water- 

 ing what dry spots there are and damp- 

 ing the walks at the same time; there 

 are always places, here and there, that 

 dry out quicker than others, and we 

 consider it very liarmfnl for a plant to 

 be very dry over night while it is in a 

 growing condition. 



Right now is the time wlien your car- 

 nations should be starting into their 

 strong fall growth and getting well 

 established in their new quarters, and 

 you should offer them every encourage- 

 ment to make a strong but sturdy and 

 well matured growth. After they have 

 a good hold on the soil there should not 

 be a particle of shade on the glass, and 

 the ventilators should be up as high as 

 you can raise them during the day and 

 lis high as you dare keeji them over night. 



About this time we are bothered most 

 by that destructive little pest the sow- 

 bug or wood-louse. They seem to delight 

 in chewing up the grass of the newly 

 (ilanted carnations, and we have seen 

 plants totally ruined by them. Mix a lit- 

 ,le paris green in some sugar and 

 sprinkle a little here and there on the 

 edge board in the evening, and if you 

 repeat ttiis regularly for a week or two 

 you will be rid of them. Don't lay it 

 around once and expect it to kill them 

 all, but keep at it until you are rid of 

 them. The first time they may get only 

 enough to make them sick, but the sec- 

 ond or third time it will do the work.

ROSES. 



Seasonable Hints. 



Cold, dani)i. and muggy seasons, like 

 the present, create just the conditions 

 most suited for the germination, and fav- 



orable to the growth, of mildew, the 

 spores of which are rarely absent from 

 the soil. 



The rose mildew (Uredo rosea) is al- 

 ways a parasite on a living plant, and 

 appears in the form of a minute fungus. 

 This originates for the most part within 

 the tissues of living leaves and develops 

 outward in pustules which burst through 

 the cuticle. The filaments penetrate the 

 pores of the epidermis, rob the plant of 

 its juices and interrupt respiration. Ev- 

 ery specimen of this fungus emits annu- 

 ally, myriads of minute spores, these are 

 scattered over the soil and foliage and 

 readily germinate when the conditions 

 are suitable. They have also the power 

 of stooling or spreading by offsets. 



Plants which through auy cause have 

 their vitality impaired are the most sus- 

 ceptible to its attacks and ravages. Keep 

 the plants growing vigorously and avoid 

 all draughts and sudden changes of tem- 

 perature, by keeping a close watch on 

 the outside atmospheric conditions, and 

 so regulating the ventilation that no sud- 

 den chill can occur in the house, especi- 

 ally during the time of watering and sy- 

 ringing. 



Have the roofs of the houses tight, 

 particularly so along the gutter-plate. 

 The foliage should, under no circum- 

 stances, be allowed to remain wet over 

 iiiglit, as this makes the foliage soft, and 

 is a very fruitful source of mildew. By 

 exercising due care along these lines the 

 leaves will be of a rich green color and^ 

 have such a firm texture that they will 

 lie nearly immune. 



As a measure of precaution the sul- 

 pnur blower should be used once a week 

 by selecting a bright, warm day, when 

 liie leaves are dry (as it is only of bene- 

 fit in a powdered form), and allowing 

 it to remain on the foliage for twenty- 

 four hours the full benefit will be de- 

 rived. 



If, as may happen, after all precau- 

 tions , mildew does make its appearance, 

 tlie most effective, safest and easiest ap- 

 jdicd remedy is still sulphur — two parts 

 of sulphur and one part air-slacked lime, 

 mixed with water to the consistency of 

 paint, and put on the pipes at distances 

 of a yard or so apart, and shutting the 

 house tight for an hour and a half. 



By selecting the coldest part of the 

 rignt for this operation there will be no 

 danger of injuring even the most tender 

 foliage. If steam is the heating power, 

 care must be taken not to paint the 

 hottest pipes, as the sulphur may fuse 

 and the fumes from sulphur in a state 

 of fusion is death to vegetable life. The 

 return jiipes will usually give off suffi- 

 cient fumes to destroy the pest. One ap- 

 plication is usually sufficient to effect the 

 purpose, but a repetition after a few 

 davs makes sure work. Ribes. 



ROSES. 



I have a small house in roses in solid 

 soil. Have been planted one year. They 

 are planted about one foot apart. They 

 are growing very rank and the flowers 

 are getting to be very small. I want to 

 help them over another winter. Have 

 every other sash oft', .so part of soil is 

 wet with i-ains and the other part dry. 

 The kinds are Liberty, Bride, Maid, Gate 

 and Perle. Had I better take out part 

 of plants or trim them back, or both? 

 I do not need the roses for six weeks or 

 two months. Soil has not been fertil- 

 izcil since roses were planted. Shall I
