BURNED COLUMBIA. 



Under separate cover I have mailed 

 you some shoots of Columbia roses, as 

 well as a few buds. They seem to have 

 been checked in some way. I wish to 

 know the cause. The root action of the 

 plants is in fine condition and the trou- 

 ble does not seem to be in that direction. 

 I have been smoking with tobacco 

 stems, to keep down the midge, twice a 

 week and fumigating once a week. 

 Could this have caused the trouble? 

 Both of my houses are affected in the 

 same way. .T. W. L. — la. 



The shoots and buds of the Columbia 

 ro^es were partly wilted, but, from the 

 appearance, they seem to have been 

 burned. During the last two weeks in 

 September we had a number of warm 

 days that were sultry. There was con- 

 siderable rain, usually followed by dry 

 winds. This caused such roses as Co- 

 lumbia and Premier to make soft growth, 

 which was sensitive to the sun's hot 

 rays and the wind, which caused them 

 to wilt ba<lly and burned the top edges 

 and the soft foliage of the rose petals. 

 This is, doubtless, the cause in your 

 case. The thicker and softer the growth 

 the more easily thej' were affected. 

 Since this sultry weather has passed, the 

 danger of burning the roses is over and 

 you will experience no more trouble 

 tliis season. W. J. K. 



BOSES TUENINO YELLOW. 



Our roses, after being rested, were 

 cut back and replanted, making a splen- 

 did start. Then, when the new growtli 

 was from three to six inches long, the 

 roses suddenly turned yellow, starting 

 at the cut-back .joint. Then, within a 

 day, the stems turned black, three or 

 four inches being thus discolored in a 

 day. When this started the weather 

 was liot and moist. Will you advise us 

 as to what the trouble is? Could the 

 shears have caused it? T>. H.— R. C. 



The shears were in no way to lilamc 

 for the yellow spots and blackened 

 stems on your roses, l)ut rather an over- 

 supply of water at the roots. This would 

 affect all the cut-back plants. Xo mat- 

 ter whether lifted or not, tlie iiiii)riineil 

 plants could better stand the moist, 

 warm atmosphere when wet at the roots, 

 as compared with those but lately 

 planted. Newly planted stock needs 

 careful watering after planting and 

 should be allowed to dry out well be- 

 tween waterings. It is safer to leave a 



little basin around each plant and to 

 water the plants individually, rather 

 thaTi to soak the whole bed or bench, 

 until the plants are making roots active- 

 ly. Then water may be applied more 

 freely. A hot, saturated atmosphere and 

 wet feet are amply sufficient to start 

 trouble in newly planted roses. You 

 can best avoid it in the future by spray- 

 ing freely, but running the plants on 

 the dry side for a time. C. W. 



KOSES FOB EASTEB. 



I have a number of rambler roses in 

 the field. Will you advise me how to 

 liandle them from now on to have them 

 in bloom next Easter ? J. M. — N. H. 



made during the last season. Do not 

 allow the roots to dry out while they 

 are waiting for the pots and pot firmly. 

 A good soil, such as suits carnations or 

 roses in benches, will be suitable. Let 

 the plants stand outdoors for some 

 weeks after potting them. It will prob- 

 ably be necessary to tie up the larger 

 canes to a stake, not too closely. Before 

 sharp frost, store the plants in si light 

 cellar or pit, which is cold, but frost- 

 l>roof or nearly so. 



Start your plants early in January, 

 with a temperature of 45 to 50 degrees 

 at first, spraying well on clear days and, 

 as the growth advances, advance the 

 temperature to 60 degrees at night, if 

 you can command this temperature. Be- 

 fore starting up the plants, it will be 

 necessary to tie them into shape. Al- 

 ways avoid cold draughts, which will 

 cause mildew and such an atmosphere as 

 will give red spider a foothold. Easter 

 comes somewhat late next year and as 

 weather conditions are variable, some 

 forcing or holding back may be needed 

 to time your flowering season properly. 

 Such a "variety as Tausendschoen will 

 l)loom a couple of weeks earlier than 

 others and need not bo started so early. 

 About three months are needed to flower 

 roses started in January. it takes 

 longer, of course, as the season advances.

In your latitude these roses can be 

 (lug up and potted about the last of 

 October. Cut away any useless wood,

DRY-BOT OB FUNGUS. 



We are sending you specimens of our 

 carnation crop. The roots seem to rot 

 off and the plants wither and die. Will 

 you kindly examine them and deter- 

 mine, if possible, what the disease is 

 which these plants have?

surrounding them to your state agricul- 

 tural experiment station. The speci- 

 mens and soil will undergo an analysis 

 there and you will then receive advice 

 on what to do. A. F. J. B. 



Your letter does not give any infor- 

 mation regarding the way your carna- 

 tions were handled and it is difficult to 

 form a definite opinion as to the cause 

 of the trouble and a probable cure. 



If these plants were established on 

 your benches and began to die in the 

 manner indicated, tliere is a fungus 

 working in the soil, which may be diffi- 

 cult to control. A liberal sprinkling with 

 air-slaked lime, watered in thoroughly, 

 would probably be as beneficial as any- 

 thing that could be recommended. If 

 the jilants were d>ig from the field and 

 l)egan to die before they became est;ib- 

 lished. it is possible tliat the roots were 

 slow in starting and began to decay 

 from too much lieat or water or botli. 

 In this case, it would be advisable for 

 you to keep your houses as cool as pos- 

 sible by giving all the ventilation you 

 can. Water moderately at the roots 

 and keep the surface of the soil open 

 by frequent scratching. 



In case these suggestions do not bring 

 relief, send a plant or two and some soil 



YOUNG GBOWTHS CUBL UP. 



My young carn.ation crop is giving me 

 some anxiety this fall. The buds on 

 ' many of the plants curl up before open- 

 ing and those that do open appear weak 

 and unhealthy. This difficulty is found 

 chiefly with White Wonder, but a few 

 of Enchantress Supreme have it also. 

 Will you kindly examine the specimen 

 sent and determine, if possible, wherein 

 the difficulty lies .' A. C. F. 0.— N. Y. 



It is not tuicommon for the first young 

 growths of carnations, after planting, 

 to curl up like the specimens submitted. 

 White Wonder does it more than most 

 varieties commonly grown nowadays. 

 Keep the soil scratched lightly during 

 the next few wei>ks and water carefully 

 until the growth is normal, which 

 will be as soon as the roots get well es- 

 tablished in the new soil. The small 

 brown spots are, no doubt, caused by the 

 stings of insects. Begin spraying with 

 one of the nicotine jiroducts and keep it 

 up faithfully throughout tlie season. 

 Watering, keeping the insects ;iway and 

 ventilating properly will be your main 

 t.osk during the next few months.
