38 GREENHOUSE MANAGEMENT. 



plants, to select a dull day for the planting, or, if u 

 does not come, the plants may be dug in the early morn- 

 ing and placed away in the flats in some cool place until 

 towards evening. With large numbers of plants this 

 will not be possible. 



The distance required by the plants in the houses 

 will depend upon the variety, the size they have attained 

 in the field, and on whether a large number of com- 

 paratively small flowers is preferred to a smaller num- 

 ber of large ones. For the former, plant so that 

 they will touch, or eight or nine inches each way, 

 while for large flowers have them at least a foot 

 apart. Many growers prefer to have the long rows 

 eight to ten inches apart, and those across the beds 

 from ten to twelve or more, thus giving a better chance 

 to work the soil. 



Dig a good-sized hole with the hand or trowel, and 

 set the plants about as deep as in the field, carefully 

 spreading out the roots and pressing the soil firmly 

 about them. As soon as planted they should be thor- 

 oughly watered, and in bright weather shaded for sev- 

 eral days, but as soon as the plants have become estab- 

 lished some or all of the shading should be removed, 

 using a stream of water and a scrub brush if whitewash 

 has been used. As a temporary shading, nothing is 

 better than to spray over the roof a thin mixture of 

 water and clay, which can be readily removed. During 

 hot weather it is well to leave every other row of the 

 shading upon the roof. 



The houses will need thorough ventilation, although, 

 upon the newly set plants, drafts of hot, dry air should 

 be prevented. Even in severe winter weather, unless 

 the houses are very open, a little air should be given for 

 a short time each day. It is possible that one reason 

 why such fine flowers are often grown in old, tumble- 

 clown houses, is that the cracks admit fresh air and let
