ERECTION AND MANAGEMENT OF GREENHOUSES. 
23 
Some grow the best when the wood is quite young and tender as 
Fuchsia, Andersonia, Adenandra, &c., others when it begins to assume 
a brownish colour, called half ripened as Heliotrophium, Goodenia, 
Pimelea, &c., and others when it has become quite hard and ripe as 
Araucaria, Aulax, Melaleuca, &c. But as a general rule half-ripened 
cuttings will do the best. Some plants however will not grow from 
cuttings of the stem at all, these are propagated by cutting off large 
pieces of the roots, planting them in pots of soil, and plunging them 
in a little bottom heat, as some species of Acacia, &c. 
All hard-wooded plants make roots best in clear sand, but soft- 
wooded kind should be planted in a mixture of loam. Therefore af¬ 
ter well draining the pots or pans, intended to receive the cuttings, 
fill them, according to the nature of the plants to be propagated. On 
no account plant soft-wooded and hard-wooded cuttings in the same 
pot. 
Some sorts will not grow readily without a little bottom heat. 
Plunge the pots in a cucumber frame, or pit of any kind, where they 
will receive the benefit of warmth. 
After putting in the cuttings, give them a gentle sprinkling of 
water through a fine rose: keep the frame as closely shut down as 
can be until the cuttings are struck, which will be in about three 
weeks or a month, with some few exceptions. Look them over, and 
water as often as they require it. 
Those sorts, requiring to be covered with bell, or hand glasses, 
will require to have the glasses taken off occasionally, and wiped, to 
prevent the cuttings from being injured by damp. 
When the cuttings have struck root and begin to grow, then pot 
them in small pots filled with soil suitable to their nature; replace 
them for awhile in the frame, and gradually expose them to the air, 
until they bear the temperature and treatment of the other plants in 
the greenhouse. 
Sow the seeds of greenhouse plants in pans, or pots, filled with a 
light soil, as early in the spring as possible; place the pots in a very 
gentle heat, keep the soil damp by covering with moss, and occa¬ 
sionally sprinkling with water; and when they are about an inch 
high, pot them off into small sized pots, and treat them in the same 
manner as cuttings.
