58 THE NURSERY. [Jak. 
ed and lie so-nie time fallow, to recruit or recover its former vigour; 
givintij it also the addition of manure, if it shall seem proper; and 
after being trenched in ridges, and having the repose only of one 
■winter, or summer, or a year at most, it will sufficiently recover its 
vegetative force, and may be planted afresh. 
It will be of advantage to plant the ground, with plants of a differ- 
ent kind from those which occupied it before. 
The tender or exotic plants of all kinds that require shelter only 
from frost, whilst young, as formerly mentioned, and by degrees 
become hardy enough to live in the open air; should, such of them 
as are seedlings in the open ground, have the beds arched over with 
hoops, or rods, at the approach of winter, in order to be sheltered 
with mats in severe weather; and those which are in pots, either 
seedhngs or transplanted plants, should be removed in October in 
their pots, to a warm sunny situation sheltered with hedges, &c. 
placing some close under the fences facing the sun, where they 
may have occasional covering -vith mats in frosty weather; others 
that are more tender may be placed in frames, to have occasional 
covering either of glass-lights or mats, &c. from frost; observing 
of all those sorts here alluded to, that they are gradually to be 
hardened to the open ground, and need only be covered in frosty 
weather; at all other times let them remain fully exposed, and by 
degrees, as they acquire age and strength, inure them to bear the 
open air fully; so as, when they arrive at from two or three, to four 
or five years old, they may be turned out into the open ground. 
The sorts requiring this treatment, are pointed out under their pro- 
per heads, in the different months. 
The Green-house kinds of all sorts, or such as require constant 
shelter in winter, are to be managed as directed under the article 
GREEN-HOUSE. 
And the hot-house or stove-plants, or such as require constant 
shelter all, or the greater part of the year, together with the aid of 
artificial heat, are to be managed as exhibited under the article hot- 
house. 
Work to be done in the JWrsery. 
Young apple and pear trees may now be pruned, agreeably to 
the rules laid down in March: though, if your stock of these is 
not very numerous; and that you are desirous to have so much work 
done out of the way, when the hurry of business comes on in spring; 
it will be quite as well to defer doing it till the end of February, or 
beginning of March. 
Trim up the stems of forest, and other hardy trees, where they 
require it; this may be done, when little else can, in the nursery; 
for, if it is performed in frosty weather, the trees will receive no 
harm by the operation, especially the hardy deciduous kinds. 
Carry well rotted dung, or compost, and lay it on such parts of 
the nursery as require it. This may be necessary to such parti-u- 
lar quarters as have been lately cleared, and that are intended to be 
planted again with a fresh stock in autumn, taking off a summer
