MONTHLY CALENDAR. 201 
THE Fern House.—Keep up a good heat, with a 
damp atmosphere, and re-pot small plants. Sow seed 
~ and prick off seedlings. 
. THE HeatH House.—Keep the house well venti- 
lated, dry, and at a mild heat. Look out for mildew, 
and use sulphur to kill it and prevent it; keep the 
plants temperate at the root, giving no water except 
sufficient to keep them half dry. Care in watering is 
now necessary. Cuttings may now be struck. 
THE GERANIUM House.—Keep the house as cool as 
possible, although a little fire will be necessary, to 
maintain a healthy atmosphere ; keep the plants half 
dry, with a dry atmosphere. Nip out the points of the 
leading growth. Those required to flower early, shift 
into the flowering pots. Admit air daily in mild 
weather, and turn the plants frequently to induce 
symmetry of growth; fumigate the house as soon as 
the least signs of the aphides appear. 
THE PINK AND CARNATION Hovuse.—These will now 
be in full go for flowers, and may be encouraged to 
mature the late buds by giving the plants some liquid 
manure. This is a good time to make the full stock 
of pipings for plants, for forcing next season (see p. 
111). Keep up a mild heat, and admit air whenever 
practicable ; but close early. 
THE CINERARIA House.—Keep the house at as low 
a temperature as possible, but frost-proof; syringe the 
plants overhead every morning with clean soft water ; 
admit all the air possible every day except when cold, 
cutting winds prevail, but even then the ground 
shutters in front may be opened; as soon as the 
aphides appear fumigate the house in the evening; 
admit all the air possible to the Calceolarias in the pits;
