400 'I'HE GREEN-HOUSE. [Mav. 
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 306, 307, and 362, which see. 
Propagating Green-House Plants. 
Continue to propagate most kinds of plants, by cuttings, suckers, 
seeds and layers, as directed in pages 308, and 363. The China and 
Otahcite 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 len\ons 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 me- 
thod seepage 257. 
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 hortcnsis. Myrtles, Pome- 
granates, 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 i^etter, especially
