CARE OF VEGETABLE HOUSES. 



The Three Essential Elements. 



Taking it for granted that the houses 

 are good and the soil properly prepared, 

 the next important task for the grower 

 is to produce the atmospherical condi- 

 tions most conducive to the growing of 

 the different crops. This is the most im- 

 portant because it is why we build green- 

 houses — to create a condition of the at- 

 mosphere more favorable than the out- 

 side. We call ourselves growers, but in 

 reality we are not. No man can make 

 plants grow; nature does that. All we 

 can do is to keep away their enemies 

 and surround the plants with condi- 

 tions most favorable to their growth. 



The three things that go to make up 

 the proper atmosphere are heat, ventila- 

 tion and moisture, furnished by the heat- 

 ing pipes, the ventilators, and the hose. 

 It may look simple to the beginner, but 

 the old, experienced grower knows well 

 the disaster that may occur by the misuse 

 of any one of the three. This is where the 

 man shows his ability as a grower, as 

 it requires the most careful study of any 

 part of the business. To be a successful 

 grower one must have endless patience 

 and untiring energy, and be always will- 

 ing to sacrifice personal pleasures where 

 they conflict with attention to the wel- 

 fare of the plants. 



I often think that we know much less 

 than we think we know about what are 

 the secrets of success in gardening, as we 

 are continually advancing new theories 

 that explode those on record and be- 

 lieved for many years by all members of 

 the craft. We must all admit that we 

 certainly do not know it all as yet, when 

 we read that Thomas Edison, the in- 

 ventor, who probably has studied deeper 

 into his trade than any other living man, 

 is quoted as saying that he estimates that 

 we know about one-billionth of one per 

 cent about anything. 



But, to go back to the greenhouses 

 ag&in, I only mentioned the above to im- 

 press upon you that I think there are 

 others who differ in opinion on the care 

 of plants who may be right in their ideas, 

 but by expressing our ideas for compari- 

 son, and weighing each carefully, we 

 may come to conclusions that will be of 

 benefit to all. 



Next wegk we will give our experience 

 on the matter of temperatures, air and 

 moisture. Borealis. 



TOMATO BLIGHT. 



We are sending some tomato leaves 

 showing a fungus which is blighting our 

 plants. Will you please inform us as to 

 the best method of treating it and when 

 to start with the treatment! A. B. 



The leaves are badly affected by toma- 

 to blight, a disease not thoroughly under- 

 stood and therefore difficult to handle. 

 Spraying with Bordeaux mixture will 

 check its spreading. The fact that it 

 never causes any serious damage to out- 

 door tomatoes leads us to believe that it 

 is caused by improper care inside. Wa- 

 tering should be done in such a way as 

 not to wet the foliage, and ventilation 

 should be attended to as carefully in late 

 spring as in winter. In May and June, 

 when the days get longer, the sun rises

RAWSON'S HOTHOUSE 

 CUCUMBER 



As a forcing Cucnmber is one of the largest and most 

 profitable crops of the Market Gardener, it is essential 

 that the very best possible strain should be sown. 

 With this idea in view we liave made selections for the 

 past few years from our Rawson's White Spine, which 

 nave resulted in a strain about two inches longer and 

 a darker green in color, with a few light spines snowiDg 

 at blossom end. This new strain we confidently 

 believe to be snperlor to any other on tlie market. 

 The results we have had at our own greenhouses with 

 the stock conclusively prove the above to be true. )4

long before the average grower, and the 

 houses are hot, close and steamy before 

 being ventilated, even if quite cool in the 

 night. This produces a weak, soft growth 

 and encourages any' disease. 



Several healthy specimens of white fly 

 came with the sample of leaves. For 

 these there is but one thing to do — fumi- 

 gate with hydrocyanic acid gas, but have 

 a care that no human being gets a breath 

 of the deadly poison. Borealis. 



STRIPED CUCUMBER BEETLE. 



We are sending you by today's mail 

 some specimen cucumber leaves that seem 

 to be diseased. The trouble first starts 

 on leaves towards the top of the vine 

 and then the otner leaves keep going, un- 

 til the plant dies. This trouble is not 

 serious, only a few vines having died 

 from it. If you can tell us what the 

 trouble is, we would thank you very much. 

 C. W. Z. 



The cucumber leaves sent as sample do 

 not seem to be diseased, simply dried up, 

 and I think by the way the vines are 

 affected, as described in the letter, that 

 the striped cucumber beetle is responsi- 

 ble for the trouble, not by what the in- 

 sect does when in the winged state, but 

 when in the form of a tiny worm. The 

 mature insect lays its eggs at the root 

 of the vine, and when the eggs are 

 hatched into the form of a worm, they 

 penetrate, and follow up the root to the 

 stalk and branches, causing the leaves to 

 wilt and burn and the branches to die. 

 All the fruit on the vine usually gets 

 soft and the entire vine soon dies. When 

 a crop once commences to go, there is no 

 hope or remedy. The vines not killed 

 usually seem, affected and cease to do 

 well. This ailment was formerly mis-
