MANAGEMENT OF PLANTS.

and they will soon come into flower, and when they 
have done flowering the heat should be kept up while 
they are making their new growth, and to get their 
shoots ripened before placing them out for summer. 
Many Greenhouse Plants will bear this heat if strong 
Plants and well rooted in the Pots, as Camellias, Ge¬ 
raniums, Fuchsias, Tree-Pseonias, &c. Bulbs are 
very good to force, as Hyacinth, Amaryllis, Ixia, 
Laehenalia, Polianthus, Narcissus, &c. Where Plants 
have been forced a season or two, they will commence 
growing at the usual time in fall they have been accus¬ 
tomed to. The Plants forced in winter must be kept 
in the Conservatory till all danger of frost is over in 
Spring, and then they should be shifted into fresh soil, 
and be kept in as cool and shady a situation as possible 
in Summer, to rest and recruit their strength. When 
persons commence forcing Plants, they must be sure 
that they can command as much heat in severe weather, 
as they commenced with, for if they keep the heat at 
the commencement, and do not keep it regularly, they 
may fail of having flowers. 
If it is only wished to preserve the plants in winter 
and let them flower as they come regularly on with the 
advance of the season, it will be only necessary to 
exclude the frost, or keep what is termed greenhouse 
heat, that is about 40 deg. at night, and 50 deg., by day 
though if you wish to have what flowers you can 
without forcing them very much, an intermediate heat 
from 40 deg., to 45 deg., by night, and from 50 to 55 
by day will suffice, and towards spring, the glass may 
occasionally rise to 60 or 70 deg. In fine sunny days, 
air must be admitted in proportion; the treatment
