FRUIT GROWING UNDER GLASS 219 



airy house, with a temperature beginning at thirty-three 

 to thirty-five degrees at night and forty to forty-five 

 degrees during the day, gradually raising it two to three 

 degrees each week until forty to forty-five degrees at 

 night and fif ty to sixty degrees during the day is reached. 

 As much air must be kept on the house as possible, and 

 an abundance of water be given. 



Liquid manure may be used every week after 

 blooming if the plants are not growing rapidly. When 

 the plants are showing bud they should be placed as 

 near the glass as possible, but the pots be shaded 

 by the foliage by placing close together, or by some 

 packing like sphagnum . moss about them. When the 

 flowers begin to open the atmosphere should be kept 

 as dry as possible. Fertilization of the flowers should 

 be done by hand with the camel's hair brush or by 

 having bees in the house. To keep the fruit from get- 

 ting into the dirt and decaying, pieces of wire netting 

 up a vigorous growth, and maintain as nearly as possible 

 can be placed on top of the pots, as seen in Figure 114. 



The aim in all stages of growth should be to supply 

 the best soil and an abundance of plant food ; to keep 

 the temperature, moisture and air of an ideal season 

 for strawberry growing outside. The best varieties for 

 forcing- are probably those that succeed best in field 

 culture, and yet few can hope to supply the exact condi- 

 tions under which they succeed in the field. I would 

 suggest the Clyde, Brandywine, Sample and Senator 

 Dunlap as among the best.
