392 THE GREEN-HOUSE. [MAT, 



Pruning and Heading. 



You may still prune, trim, and head, such of your plants as are 

 in need of that treatment ; but let it be done early in the month, 

 and as directed in pages 298, 299, and 354, which see. 



Propagating Green-house Plants. 



Continue to propagate most kinds of plants, by cuttings, suckers, 

 seeds and layers, as directed in pages 300, and 355. The China and 

 Otaheite roses, may now be encreased abundantly by cuttings, they 

 will strike root freely, and flower handsomely in autumn. 



Seedling Oranges and Lemons. 



The seedling oranges and lemons, raised from the late sowings of 

 last year, should early in this month, if not clone before, be trans- 

 planted into separate pots ; they ought to be watered immediately, 

 and shaded from the sun till newly rooted. If plunged into a hot- 

 bed, or bark-bed for two or three weeks, and carefully shaded from 

 the mid-day sun, it will greatly facilitate their rooting, and promote 

 their growth. 



The early sown seedlings may, towards the latter end of the 

 month, be planted separately into small pots, and treated in like 

 manner. 



You may yet sow the seeds of oranges and lemons in pots or 

 boxes, for stocks ; they will rise freely without any artificial heatj 

 and make tolerable progress during the season. 



Inarching. 



Inarching may now be performed on oranges, lemons, and any 

 other plants that you desire to propagate in that way, for the me- 

 thod see page 249. 



Bringing out the Green-House Plants. 



About the tenth of this month, two or three days earlier or later, 

 according to the season and situation, you may, in the middle states, 

 begin to bring out the more hardy kinds of green-house plants, 

 such as the Viburnum Tinus, Prunus Lauro-cerasus, Prunus lusi- 

 tanica, Nerium Oleander, Hydrangea hortensis, Myrtles, Pome- 

 granates, Oranges, Lemons, Magnolia grandiflora, Lagerstrcemia 

 indica, Daphne indicum, and all the other hardy kinds : the more 

 tender, and tenderest sorts, are to be brought out successively, so 

 that the entire may be abroad by the twentieth of the month. 



In the eastern states this work must be delayed for a week or two 

 longer, according to the respective climates, and not attempted, 

 while there is any danger remaining from night frosts ; but when 

 this is over, the sooner the plants are taken out the better, especially
