416 THE GREEN-HOUSE. [MAY 



PROPAGATING GREEN-HOUSE PLANTS. 



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

 seeds, and layers, as directed on pages 324 and o77. The China, 

 tea-scented, and Bourbon roses may now be increased 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 done 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 heat, 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 method 

 see page 267. 



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 lusitanica, nerium 

 oleander, hydrangea hortensis, myrtles, pomegranates, oranges, lemons, 

 magnolia grandiflora, lagerstroemia 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 the 

 more hardy kinds : by no means ought they to be continued a day 

 longer in the house than their preservation from frost and cold severe 

 weather requires, as at this season the young shoots of many kinds 

 will be growing freely, and if deprived of the benefit of the open 

 air, they would become weak and sickly. 



Generally, when the plants are first brought out of the green-house,
