the soil on the benches and have tl" 

 soil in the pots and the stems perfectly 

 dry. We have found this out by per- 

 sonal experience and know it to be a 

 fact. Outside of this we have never 

 been able to find any advantage in the 

 use of these bottomless pots.

Twisted Growth on Joost. 



What causes the twisted growth on 

 Joost carnation? A good deal of the 

 new growth comes curled or twisted, 

 some of the flower buds being deformed. 

 * We have noticed it on Scott also. Both 

 varieties are affected some in the field. 

 A good many growers speak of the trou- 

 ble. We notice that the plants grow out 

 of it after getting established. Does 

 any one know of a remedy or preven- 

 tive? Several Inqhibebs. 



I cannot say positively what might be 

 the cause of your carnations coming 

 with twisted growth in the field without 

 having a specimen before me. The fact 

 that it grows out of it in the house in- 



potassium sulphide you recommended for 

 mums. Is that right, and if so, how 

 often should I apply it? 



Subscriber. 



Tlie disease that is affecting the car- 

 nations is not what is usually called 

 rust, but is what we call Fairy-ring 

 spot, and is caused by a fungus. He di'd 

 quite right in spraying them with a so- 

 lution of potassium sulphide or any 

 other fungus destroyer. If it does not 

 seem to check the disease he might try 

 the copper solution. I would apply it 

 about twice each week at first and if it 

 seems to be checked after a few weeks I 

 would continue to apply it once each 

 week for a few weeks longer. Apply it 

 to the whole batch of plants, as it will 

 help to stop the disease from break- 

 ing out in new spots. Wherever he sees 

 a "diseased branch he should cut it oft' 

 and burn it, as it will spread if left on 

 the plants. Give all the air possible and 

 keep the plants dry except when apply- 

 ing the fungicide, as like most all other 

 fungus diseases it requires moisture to 



A House of Beauties at the Establishment of Poehlmann Bros. Co., Morton Grove, IlL 



dines me to believe that it is not caused 

 by a disease, but rather by some insect 

 or grub or the condition of the soil and 

 weather. We have never been troubled 

 in that way, and so I cannot speak from 

 experience; but examine your plants and 

 see if you cannot find something that 

 is feeding on the sap of the young stems, 

 or dig in the soil and look for grul) 

 worms. Too much manure and water and 

 a very hot sun might also be the cause 

 of it. A. F. J. Baub. 



Fairy-Ring. 



Please tell me the best remedy fr 

 carnation rust. I have a bed of Mjs. 

 Fisher for summer blooming that were 

 the first to show the rust, and my win- 

 ter carnation plants were grown close 

 to them. The latter were housed August 

 25 and did not show any sign of rust 

 until about a week ago. It has appeared 

 on a few plants in different parts of 

 the house, which contains 1,000 plants. 

 I have commenced to use the solution of 



make it active. Pick all the open blooms 

 before applying the fungicide, as.it wii 

 discolor them. A. F. J. Baub. 



Carnations in House with Roses. 



Will it do to have carnations in the 

 same house with roses? That is, will 

 the sulphur on the pipes hurt the carna- 

 tions? I have a bench 60 feet long and 

 a rose bench same length, also a bench 

 of same length containing miscellaneous 

 pot plants. When I get my new house 

 done will move the pot plants into it 

 and put the present one all into carna- 

 tions, roses, or both. M. W. B. 



I would not advise you to plant roses 

 and carnations in the same house, be- 

 cause either the one or the other will 

 be sure to be a failure. The two require 

 conditions so widely different that if 

 you suit the one you injure the other. 

 In the first place, your roses want 58 tn 

 60 degrees, while your carnations want 

 50 to 55 degrees; 55 degi'ees will not 

 be warm enough to grow roses profita- 



bly, while 58 degrees will cause your 

 carnations to grow soft, with small 

 blooms and weak stems. If you give 

 enough ventilation to suit your carna- 

 tions you will continually have your 

 roses full of mildew, and if you keep 

 the temperature high enough and moist 

 enough for roses you will again have 

 your carnations soft and worthless in 

 general. The sulphur of which you seem 

 afraid will not injure your carnations 

 in the least. 



It would pay you much better to 

 plant your house with either the one or 

 the other and then buy what blooms you 

 need of the one you do not grow. If you 

 have your new house finished in time 

 you should of course plant your roses in 

 the one house and the carnations in the 

 other, or if your new house will not be 

 finished for another month and you have 

 the carnation plants on your hands, pot 

 them in 4 or 5-inch pots and then plant 

 them on the benches as soon as you get 

 the house ready. 



Judging by your letter, it would seem 

 as though you haven't your roses plant- 

 ed yet. If you have not you would do 

 far better to plant all your space in 

 carnations. It is early enough yet to 

 have fairly good success with carnations 

 that are planted now or right soon, but 

 you cannot have good success with roses 

 that are planted in October. Next sea- 

 son I would advise you to arrange one 

 house for roses and the other for carna- 

 tions. You can grow much of your pot 

 stuff in a carnation temperature, but 

 some of your plants will want a rose 

 temperature, and so you see you will be 

 ahead all around. A. F. J„ Baub. 



Dry Stem-Rot. 



I send some branches of Lawson car- 

 nation. Upon examining the stem you 

 will find part of it dried up. This 

 spreads and results in the decay of the 

 whole branch. What is the origin of the 

 trouble and how can it be prevented? 

 The carnations were planted on the 

 benches out of pots, but the decay is also 

 to be found on plants grown in the fieldi. 



M. S. 



The branches sent have not yet reached 

 me, but from the description I can plain- 

 ly see that the trouble is due to what 

 we know as dry stem-rot. We have had 

 an occasional plant attacked by this dis- 

 ease, but never enough to do any serious 

 damage, and so we have never sought a 

 remedy. When we see a plant affected 

 with this disease we jerk it out at once 

 and bum it, to avoid any chance of the 

 disease spreading. 



It is a fungous disease, and no doubt 

 the copper solution or the potassiiun so- 

 lution would help to check it. This dis- 

 ease is not caused by moisture, and so 

 I don't think that dusting lime or sul- 

 phur or anything of that nature would 

 help matters any. A few years ago we 

 thought that by cutting away the dis- 

 eased branch considerably below the af- 

 fected part we could save the plant, but 

 we found that in most cases the entire 

 plant soon went, too.

Prevention of Disease. 



In my notes last week reference was 

 made to the use of Grape Dust. I wish 

 to say further that this preparation is 

 an excellent preventive of disease. Hav- 

 ing seen it extensively used by rose grow-
