What You Need to Know 7 



a real "hot" house is needed. But the beginner 

 usually has a lot of needless worries over the 

 "temperature problem." In the outdoor gar- 

 den you cannot maintain a special temperature 

 for each different bed of flowers. Asters and 

 Tea Roses, Snapdragons and Tuberous Bego- 

 nias, Lettuce and Butter Beans, grow in all our 

 gardens side by side, or nearly so. Now Asters 

 and Snapdragons and Lettuce are "hardy" or 

 cool-temperature plants; while Tea Roses and 

 Tuberous Begonias and Beans are "tender," or 

 warm-temperature plants. Out of doors, one 

 doesn't try to grow Head Lettuce during the heat 

 of midsummer, nor Beans during early spring. In 

 other words, gardening is adjusted to conditions. 

 It is just the same in the glass garden. If 

 you have a "cool" house and a "warm" house, 

 or a two-compartment house (and if there be 

 only one house it should have this division), 

 naturally it gives you more of a range than if 

 you have but one general house. Where two 

 houses are available, usually one is run at 45 to 

 50 degrees (night temperature), and the other 

 at 55 to 60 degrees. But in a single house, run 

 at 50 to 55 degrees, yow can grow in a fairly 

 satisfactory way most of the things that can be 

 grown in the two houses. Asters and Roses,
