Calendar of Operations for All Classes. 169 
Tree Carnations. 
The natural rise of temperature will now be en- 
couraging vigorous growth and all the earlier rooted 
plants should, therefore, be transferred to cold 
frames and freely ventilated on all favourable occa- 
sions. 
Keep a close watch on the plants and re-pot the 
more advanced as well as the vigorous growing varie- 
ties before the roots become pot-bound, otherwise 
growth will be stunted and checked. When spoiled 
in this way by neglect it takes some time to get 
them into vigorous growth again, so that they can 
scarcely make such fine specimens by the time they 
come into flower as well-tended plants would. by 
the end of the month the sashes may be left off 
night and day, and the night dews will give them 
a healthy look. 
Malmaison Carnations. 
During the month this section of Carnations will 
flower freely, especially towards the end of it. As 
the buds become ready to expand tie a thin piece 
of raffia round the calyx to prevent it from bursting. 
India rubber rings for the purpose are easily ob- 
tainable at reasonable prices and save a deal of time 
in tying by simply slipping an elastic band over each 
bud. More water will now be required than during 
the early months of the year. A temperature of 50 
deg. at night will be sufficiently high with plenty of 
air on fine days. Take off the small side shoots for 
cutting that are too high up for layering. 
Marguerite Carnations. 
Plants in the cold frames will now be rapidly 
advancing, and all those intended for planting in 
the open towards the end of the month should be 
freely ventilated night and day, and as the time for 
this operation draws nigh take the sashes off al- 
together. 
American Carnations. 
The treatment given to tree Carnations will apply 
to this section generally; but as most of the 
American varieties are of more vigorous growth than 
the better known tree Carnations they will require 
earlier re-potting and in some cases rather larger 
pots. Give them all the light and air possible or 
leave them fully exposed night and day when the
