April.] THE GREEN-HOUSE. 361. 
the weather is mild and calm, and let them continue so, till the cold 
of the afternoon begins to increase; provided, that the air conti- 
nues moderately warm all the time. Too much confinement at 
this season, especially towards the end of the month, when the heat 
of the weather increases, would do infinite injury to the plants in 
general, but especially to the early shooting kinds; for if drawn up 
weakly in the house, they would not be in so good a condition to 
bear a removal into the open air in the early part of next month, as 
if their vegetation had been retarded by the admission of a due and 
salutary circulation of air, in the house, at a!l favourable opportuni- 
ties. 
Tfatering. 
The plants will now require frequent waterings, giving only a 
little at a time; but especially the oranges, lemons, myrtles, olean- 
ders, African heaths, jasmins, coronillas, justicuis, arbutus, laurus- 
tinus, and most of the woody kinds: and also the herbaceous green- 
house exotics, will require to be occasionally refreshed with mode- 
rate waterings. 
Let the whole plants, »*i general, be often looked over, to see where 
water is wanted, and let such as need it, be supplied therewith, ac- 
cording to their i-espective necessities; for it is now an indispensa- 
ble article. But moderation and discretion ought to be observed, iu 
the dispensing of it, especially, while the plants are in the house, 
and particularly to the succulent tribe The latter, such as Aloes, 
Agaves, Euphorbias, Cactuses, Crassulas, Stapelias, Mesembryan- 
themums. Sec. being naturally replete with moisture, do not require 
much water; to those and other plants of the same nature, it should 
be given, only when the earth in the pots appears very dry, as too 
much would rot them. 
Shifting Plants into larger Pots and Tubs. 
Such of your plants as require to be shifted, into larger pots, or 
tubs, may now be brought out in a mild warm day, and taken out of 
the pots or tubs in which they have stood, with the balls of earth 
entire, about their roots; then cut away such roots, on the outside, 
as are matted or appear dry or decayed, and also, some of the earth 
round the ball. 
Having good, sound, fresh earth, in readiness, put some into each 
new pot or tub, previously placing a hollow oyster shell, or such 
like, with the concave side under, over each hole in the bottoms; 
then set each plant, with its ball of earth, prepared and dressed as 
above, into the middle of the pot or tub, and fill it up with fresh com- 
post, so as that the new earth may cover the crowns of the roots, 
an inch deeper than before. 
According as the plants are thus potted, let them be immediate- 
ly watered, and returned to their places in the green-house, admi- 
nistering the water occasionally afterwards, as their respective ne- 
cessities may require.
