CARE OF VEGETABLE HOUSES. 



Temperature. 



There is much difference of opinion as 

 to the best temperatures for different 

 crops, but where one is in doubt he will 

 usually be on the safe side by choosing 

 the lower temperature, as it is less liable 

 to injure than a temperature held too 

 high. I feel safe in saying that few 

 growers use enough ventilation or keep 

 their temperature low enough. If they 

 did so they would have less trouble with 

 disease, etc., as their plants would be 

 much stronger and more able to with- 

 stand anything that might be injurious. 

 But there is a limit to all things and one 

 must not let the temperature be too low, 

 or let there be too much difference in the 

 day and night temperature. This is the 

 cause of more losses than any other fea- 

 ture in the care of greenhouses. For in- 

 stance, if you are unable to keep your 

 cucumber or tomato houses above 55 de- 

 grees or 60 degrees at night, in a stretch 

 of severe weather, don't run them more 

 than 15 degrees or 20 degrees higher in 

 the daytime, or the plants will make a 

 soft growth and be unable to stand the 

 chill at night. It is better to make less 

 growth and have it strong and hardy. 



On the other hand, if you are sure 

 that you can keep your houses up to a 

 night temperature of 65 degrees or 70 

 degrees at all times, you will be safe 

 in carrying them 15 degrees or 20 de- 

 grees higher on bright days. It is un- 

 wise to let the night and day tempera- 

 tures be more than 20 degrees apart. 



We have found the temperature as 

 given below most satisfactory:

Tomatoes .. 65° 70° to 75° 75° to 80° 



encumbers .68° to 70° 75° 80° to 85° 



Asparagus, peppers, melons and beans 

 require about the same temperature as 

 cucumbers. 



The grower must be the judge of the 

 day temperature. If the weather is mild 

 ■ enough to ventilate all day, the temper- 

 ature can be higher than if there is no 

 air on the houses. A high temperature in 

 a closed house is injurious. A house may 

 be 10 degrees warmer where there is ven- 

 tilation on, and not seem so warm as the 

 one with lower temperature and no air. 



The condition of the soil should also 

 be taken into consideration. When a lit- 

 tle dry and too late in the day to water, 

 the high temperature may evaporate 

 moisture from the foliage faster than the 

 roots can supply it and consequently the 

 plants wither, which is very injurious. 

 In the first place, when the roots are un- 

 able to supply the evaporation, the plant 

 has no moisture to make it grow; sec- 

 ond, it causes the plant to grow hard 

 when too young, and many times the foli- 

 age is burned, A lower temperature in 

 this case would prevent the rapid evap- 

 oration of what moisture the plants have 

 and keep them from wilting until sup- 

 plied with water. 



Moisture. 



The watering and syringing should be 

 done early in the day, so that the foliage 

 will dry off before night, and syringing 

 for red spider, etc., should be done only 

 on bright days. The soil also needs less 

 water on cloudy days, as the evapora-

RAWSON'S HOTHOUSE 

 CUCUMBER 



As a forcing Cucumber 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 have made selections for the 



East few years from our Rawson't. White Spine, which 

 ave resulted m a strain about two inches longer and 

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

 at blossom end. Tbla new strain we confidently 

 believe to be saperlor to any other on the market. 

 The results we have had at our own greenhouses with 

 the stock conclusively prove the above to be true. % 

 oz., 35c; oz., 60c; 4 oz., «1.50; lb., $6.00.

tion is decreased and the roots are not 

 called upon to work so fast. Over- 

 watering causes the soil to become soggy 

 and sour and causes the roots to decay. 

 "When the soil is too wet, the plants, not 

 having to send far for sufficient moisture, 

 make few roots and soon become top 

 heavy. Young plants always do better 

 when kept a trifle dry, but not so dry 

 as to suffer. They make more roots seek- 

 ing for more moisture, and when well 

 equipped with roots and nicely started 

 they will use much more water and grow 

 all the faster for it. 



When the drainage from the beds or 

 benches is good, so that when well wat- 

 ered the surplus drains off quickly and 

 leaves the soil just moist, then you can 

 water often without danger. Good drain- 

 age is the safety valve for careless water- 

 ing and should biB had even by the most 

 careful growers. Bobealis.
