ROSE GROWING UNDER GLASS

Questions by our readers In line with any of the topics presented on this page will be cordially received and promptly answered 

 by Mr. Euziclja. Sucli communications should Invariably be addressed to the office of HORTICULTURE. 



The Outside Roses 



In localities where the frost has already cleaned up 

 the soft plants, the foliage on all the outside growing 

 roses will be practically gone and the plants can be pre- 

 pared for their wintering. A light mulch can be given 

 of any material that may be on hand. It is best not to 

 apply too much at first, for the weather generally re- 

 mains quite warm, and the plants need no protection 

 until after severe weather sets in. AVe never try to save 

 the old wood on the plants, and always apply the mulch 

 along the bottoms of the plants, and then cut them 

 down later in the winter. This refers to the Tea roses 

 that are planted outside for summer blooming, and has 

 nothing to do with the Hybrid Perpetuals and other 

 hardy stock that is never grown inside, and that require 

 difEerent treatment. 



The Sod Lot 



Just what to do with that piece of ground that was 

 robbed of most of the sod for sod heaps, is a question 

 often turning up in the fall wheu the sod heaps are be- 

 ing put up. It is waste to allow the land to lie idle and 

 open to the action of the heavy winter rains and winds. 

 This is especially true of places having but limited 

 grounds. Do not allow this land to lie open by any 

 means. The very simplest, and no doubt the best way, 

 is to plow it up and sow in plenty of rye, say two bushels 

 to the acre. If this can he done early enough in the 

 season a little sand vetch can be added, and this mixture 

 vnll make an excellent green manure to plough under 

 in the spring. A little bonemeal scattered all over the 

 land before sowing the rye will make it take hold of the 

 soil better, thus making a better root system, and also 

 will send it right up when spring comes, which is all 

 the better for the ploughing under. 



Old Greenhouse Soil 



Now that the rush is over, and the weather has be- 

 come cooler, making work much more pleasant, the heaps 

 of old soil that have been wheeled out of the houses dtir- 

 ing planting time, can be disposed of. Do not apply 

 the old soil to fields where you intend to take sod from 

 in the near future, for there are all kinds of germs and 

 fungi in the soil that will take a long time to die, and if 

 the soil is brought into the greenhouse too soon after it 

 has been used once, these spores are very apt to show 

 vigorous signs of life and may make some trouble for 

 the growers. Keep the old soil to spread on fields where 

 farm crops are to be gown for a while to come at least. 



Tobacco Stems in the Walks 



Now that the ventilators will soon be closed a little 

 more, the old way of k(3eping out greenfly, wallbe^coming 

 into use again. ' This consists of covering all tli'e walks 

 with fresh tobacco stems, the odor of which will mean 

 death to all the young fly. , This system is good wherQ 

 the houses are unusually dry, but in moSt cases we find 

 that these tobacco stenis in the walks keep the atmo- 

 sphere of the houses too damp to be liked by most mem- 



bers of the rose family. With so many of the good to- 

 bacco preparations to choose from, we would certainly 

 do away with this old method that not only makes the 

 houses damp, but also makes them all but agreeable to 

 the health of those who have to work in them. 



Using Up the Old Boards, etc. 



Every now and then a new fire is started in one of the 

 boilers which gives us an opportunity to dispose of some 

 of the old boards that have a habit of accumulating in 

 spite of an occasional clea-n-out. Never can these be 

 used to a better advantage than to burn them up in the 

 boilers and thus get a little out of them in heat. Break 

 up all the old boxes that are worse than useless, and 

 burn them. Keep the place looking neat as much as 

 possil)le. All the most successful places are very neat. 

 That is why they are successful. 



Ammoniacal-Copper-Carbonate Mixture 



Should blackspot make its appearance among the 

 Beauties, there is nothing better than a spray of the 

 above mixture applied with a fine nozzle so as to cover 

 the aft'ected leaves as much as possible. This will not 

 cure the spot by any means, but will go a great ways 

 towards preventing it from spreading, and if the grow- 

 ers use a little judgment in caring for the plants they 

 will soon pull out of it. 



Care of Plants to be Used lor Propagating Wood 



Be especially careful not to allow spot or any other 

 disease to make its way into the houses where the wood 

 will be taken for cuttings when the season comes. Plants 

 that have been free from disease will give young plants 

 that will resist disease surprisingly. We find that cut- 

 tings taken from plants that have never had any spot, 

 will begin to get spot only after the others are almost 

 dead from it. The same we find is true with mildew. 

 The plants that have never had any mildew are not so 

 likely to get it. Not that it is safe to think that because 

 the young plants came from stock that never had any 

 disease, one can disregard the health rules. All the rules 

 must be observed as much as ever, and this, and this 

 only, will keep the plants in perfect health. 



Begonia Florence Nightingale 



We are indebted to the Gardeners' Clirouicle for the 

 picture which adorms this week's title page. The tuber- 

 ous rooted begonias enjoy deserved popularity, both as 

 outdoor or greenhouse subjects, especially those of com- 

 pact free-flowering character, good form and texture of 

 petals, and with moderate sized flowers able to hold 

 themselves up gracefully. This variety, which well com- 

 bines these requisites, was given an award of merit by 

 the Eoyal Horticultural Society when exhibited last year 

 by Blackmore & Langdon at Holland Park.
