308 '^HE GREEN-HOUSE. [March. 
harder-wooded exotics, so as sometimes many of them decay or 
mould; and which, where they occur, should now be pruned away: 
likewise pick off all decayed leaves. 
Giving fresh Earth to the Pots of Gi'een-house Plants. 
The oranges, and green-house plants in general, which do not 
require shifting, should at this time, have some fresh earth added 
to the tops of their pots or tubs; it will encourage the plants great- 
ly, and it is soon done. 
First loosen the old earth, in the lops of the tubs, or pots, quite 
to the surface of the roots, but so as not to disturb them, and loosen 
it also down round the sides a little way; then take out the loose 
earth and fill up the pots with some that is new, and give them a 
moderate watering. 
Sow Seeds of Green-house Plants, Sfc. 
A hot-bed may be made the beginning of this month to sow the 
seeds of tender plants, either of the green-house or stove kinds. 
The bed should be made either of hot dung, or fresh tanner's bark, 
and covered with frames and glasses; or if made of hot dung, lay 
eight, ten or twelve inches of tan-bark at top, either new or old, 
both in which to plunge the pots, &c. and to continue longer a re- 
gular heat. 
The seeds should be sown in pots of light earth, and these 
plunged to their rims in the tan, and moderately watered at times, 
as you see occasion. 
Where tan cannot be obtained readily, make the bed of hot dung, 
three feet high; set a frame on, and when the burning heat is over, 
lay on four or five inches depth of earth; then fill some middling 
small pots with fine light mould, sow the seeds therein, and cover 
Ihem lightly with sifted earth; then plunge the pots in the earth on 
the bed, and put on the glasses. 
Let the pots in general be frequently sprinkled with water, and 
when the plants appear, give them fresh air, by raising the glasses 
behind a little way. Observe to keep up the heat of the bed, by 
applying a lining of fresh hot dung, when it declines much, and 
protect them occasionally from the too powerful influence of the 
mid-day sun. 
Sowing Kernels of Oranges for Stocks. 
Now is the time to sow the kernels of oranges and lemons, in 
order to raise stocks to bud any of those kinds of trees upon. 
The best method of sowing these kernels is this: fill some mid- 
dle-sized pots with very good earth; sow the kernels in the pots, 
and cover them half an incli deep, with earth; then plunge the pots 
into a hot bed, and let them be frequently watered. See the Green- 
Aottse, next month.
