THE CULTURE OF ROSES UNDER GLASS.

frost, and if the temperature inside the house does not fall below 
32°, nor rise above 40° until the end of January, so much 
the better. By the middle of January these fresh-planted Roses 
may be pruned, but in after years it will be advisable to prune 
them a fortnight earlier. Having said thus much about Eoses 
planted in the ground, I will now refer to those intended to be 
grown in pots. It is quite hopeless to take plants from the open 
ground and pot them, and expect them to do well the first 
season under glass. They resent such treatment more than 
any other plant I know, and more especially does this apply 
to the H.P.'s. It is most important, therefore, to have plants 
prepared for their new life, and these must have been grown in 
pots at least one year to have become established, and if they 
are not already in the possession of the amateur, he must 
purchase them. They are not very expensive, seeing the number 
of years they will flourish if properly treated. As Eoses in pots 
should be carefully overhauled, and repotted into larger pots if 
the roots are overcrowded, or top-dressed, as each plant may 
require in September, it is about this time that plants should 
be purchased, and those supplied by any well-known Eose-grower 
should not require repotting ; but still it is safest to examine 
their roots and ascertain if they are pot-bound or otherwise. 
This Avill save much disappointment at the time of blooming, 
and I am a staunch believer in the old axiom, " If anything is 
worth doing at all, it is worth doing well." If you are satisfied 
that the roots are in perfect health, and have plenty of room, 
the plants may be removed to some shady spot, the north side of 
a brick wall for preference, and there stood upon pieces of slate, 
or ashes an inch thick, to prevent worms from finding their way 
into the soil through the drainage holes at the bottom of the 
pots. They must be watched as carefully now as if they were 
under glass, never allowing the ball of earth to become suf- 
ficiently dry as to leave a crack between the ball of earth and the 
pot. At the same time water must not be given too liberally, as 
this is the resting season for Eoses in pots. They may remain 
under this treatment until November, when they should be put 
into cold frames, or be protected in" some way from severe frosts. 
Four or five degrees will not hurt them. About the end of 
December the Eoses in pots may be put into the house I have 
described, and may be pruned a fortnight later. The soil
