!272 Gardening Under Glass 



after the plants are properly established, when 

 watering give a thorough watering sufficient to 

 wet the soil from top to bottom; then no more 

 until absolutely necessary. 



True, plants cannot talk, but the grower that 

 takes a deep interest in the culture of his pets 

 will soon learn by the appearan-ce of their foliage 

 when they are in need of moisture. Continual 

 watering with no chance to dry out will sour or 

 ruin the best of soil. The same may be said 

 about spraying. By directing the force in their 

 proper channels a house of Roses can be sprayed 

 effectively without saturating the bench. To- 

 ward fall will test the rose-grower's skill as 

 much as any time throughout the year. At that 

 time, or say just before starting the fire, good 

 judgment mlist be used as to syringing. In all 

 probability, too much moisture would be incen- 

 tive to black spots and fungous growths. In the 

 fall they should be sprayed only when the 

 weather is clea*r — in the morning so that the foli- 

 age will be dry before night. Firing and careful 

 curing will demand close attention in the fall, 

 especially when the atmosphere is damp and 

 foggy, or say when the night temperature drops 

 much below 60 degrees. It is then policy to use 

 a little fire heat — just enough fire heat to drive 

 the damp air out. Never close a rose house
