78 How TO Grow Cut Flowers. 



Not that every day in this respect is like the one that 

 preceded it, in which the same treatment is required, 

 but the days are rare that ventilation in some form can- 

 not be given. 



It must be borne in mind constantly that the health 

 and vigor of your plants, and that their ability to af- 

 ford you remuneration during the winter, is largely de- 

 pendent upon the growth they make previous to No- 

 vember. If the heat is extreme, throw wide open every 

 ventilator, and these are the days when you reap the 

 benefit of having a house stand by itself, with nothing 

 joined to it to radiate heat or impede a free circulation 

 of air through the doors in the walls. These ventila- 

 tors should be shut at night unless the temperature is 

 extremely high, and gives indications of continuing 

 so through the night, but as long as possible leave roof 

 ventilation open night and day. 



Also in seasons of extreme heat, while syringing 

 freely, be careful not to saturate the soil, as it tends to 

 soften and enfeeble the growth. 



As fall approaches, gradually lessen the amount of 

 air at night, tempering it to the weather, but still leav- 

 ing on all that the plants will bear without engender- 

 ing mildew. If the wind is raw, shut the ventilators 

 on the side from which it comes, keeping the other side 

 open, but not allowing strong drafts of cool air to blow 

 directly on the plants.
