GREEN-HOUSE — REPOTTING.

Edinburgh, where there are two large houses devoted to their 
culture; and through the whole year a continued profusion 
of bloom is kept up. Some of the plants are eight feet in 
diameter and fourteen feet high. The soil used is a coarse 
sandy peat. Pots drained with potshreds, and pieces of free- 
stone are put down the sides of the large pots and tubs ; where 
these can be had they are essential to the culture of moun- 
tainous plants, preventing them from being saturated with 
moisture, or from becoming dry, thus keeping the roots in a 
medium state ; for if once the roots are allowed to get tho- 
roughly dried, no art of the gardener can recover them. This 
may be the true reason why they are said to be difficult of 
cultivation. 
In the summer season, the pots must be kept out of the 
violent sun, for in a few hours the pot would become heated, 
dry the roots, and cause death, or a brownness of foliage 
which would never again become natural. In winter, too, 
much fire heat will also hurt them. They only require to 
be kept free from frost, need a great deal of air, and plenty 
of light ; consequently, should be placed near the glass, that 
they may have the benefit of all the air that is admitted. 
Their flowers are as varied in shape as variety or colour, but 
they all partake of a wax-like nature, and are very persistent. 
(Soil No. 5 for young plants : when older, No. 6 will do 
better.)
