362 THE GREEN-HOUSE. [Afhil. 
ders, African heaths, jasmins, coronillas, justicias, 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 all of the plants, in general, be often looked over, to see 
where water is wanted, and let such as need it be supplied there- 
with according to their respective necessities, for it is now an in- 
dispensable article. But moderation and discretion ought to be 
observed in 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, 
mesembryanthemums, &c. 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 
around 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 
compost, 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 immediately 
vi^atered and returned to their places in the green -house, adminis- 
tering the water occasionally afterwards, as their respective neces- 
sities may require. 
Fresh Earthing the Plants. 
Such of the plants as do not require shifting into larger pots, 
&c. should be refreshed with new earth, as directed in page 308; 
after which, give them a moderate watering and replace them in 
the green-house as before. 
Trimming and Cleaning the Plants. 
Where any decayed, straggling, or ill placed branches appear, 
either cut them off close, or prune theni, so as to give the plants a 
neat and becoming form. 
Pick off" all decayed leaves as they appear, and suff*er no weeds 
of any kind to grow in the pots; keep them free from moss, &c. by 
stirring the surface earth frequently; wash and clean the floor of
