remain where it is lower than 45° in the night, for if such occurs, as already 
stated, they receive a check that materially interferes with their progress the 
ensuing year. 
As soon as the new year comes in, give them, as recommended last season, a 
little more heat to induce early growth. Again, at the end of February, repot, 
giving them 3 in. more room, treating as before in respect to heat and moisture. 
Again stop the points of the shoots, after which treat them in every way as 
recommended for the preceding summer. In the autumn, when the plants set 
their buds, and get their growth well matured, it should be determined what 
they are intended for. If the object is to get up large specimens as quickly as 
possible, then the preceding year’s practice must be repeated. If the plants are 
required for decoration, which, if all has gone on well, they will be well adapted for, 
they must now be kept back as required, introducing a few at a time into heat; 
but whilst they are comparatively young, no severe retarding should be employed, 
as it has a tendency to induce a stunted condition, which it is difficult to get 
them out of. The plants should receive 3-in. larger pots each year until they get 
into such as are 15 in. or 16 in. across, when by the use of a little manure-water 
they can be kept in good condition. All through the existence of these plants, 
an immunity from insects is the first consideration, as, if ever allowed to suffer 
from thrips or red-spider, it has the effect of producing a stunted condition that 
prevents their making any satisfactory progress.—-T. Baines, Southgate,

E find that Primula cortusoides amoena* as well as amcena alha,^ and amcsna 
lilacina^ grown in pots, are great acquisitions, coming into bloom early, 
and enlivening the front lines of conservatories, when mixed with Tulips, 
Lily of the Valley, &:o. The large trusses are also in demand for cut 
flowers, for which they are well adapted. When they have done flowering, let 
all the pots be got to the potting-bench and the plants examined and repotted, 
using good rich loam, with leaf-mould and sand. When potted, plunge them in 
a shady comer where the mid-day sun will not strike them. Let them be well 
attended to with water throughout the summer when dry, giving manure after 
the pots become full of roots, but withholding it when there are signs of the 
foliage getting yellow. They should at this stage be lifted and stood in a cold 
frame if convenient, but this is not really necessary, and if very sharp frost should 
come a good sprinkling of litter may be thrown over them. If in a frame, never 
let them get dry ; and when they begin to grow give more water, raise them close 
to the glass, and give plenty of air to keep the foliage strong and dwarf. If they 
are allowed to get partially into bloom in the frame before they are taken to the 
conservator}’’, they last longer than when excited into flower with a little heat. 
There are several forms of Dianthus hyhridus which are useful at the same time.
