The Greenhouse and Frame 249 
should be carefully done, thinning out all weak shoots, 
and cutting the stronger ones well back to keep the 
plants within reasonable bounds. This subject has been 
fully dealt with in chapter VII. Water will have to be 
judiciously given to begin with, and plenty of air admitted 
to ensure a healthy growth and prevent attacks of insects 
or mildew. 
As growth proceeds, and the plants come into dower, 
manure water may be given once or twice a week. Of 
all insects, Greendy is the greatest enemy to the Rose. 
Should this pest make an appearance, the house must be 
fumigated with XL-A11 Insecticide, &c. 
Mildew is the most troublesome disease, and should 
be immediately dealt with. Ewing’s Mildew Composition 
is very effective, or, if the attack be only a slight one, 
sulphur dusted well into it will check it. 
It is not advisable to cover the roof of a small green- 
house with Roses, as plants growing under them do not 
have a good chance to develop. 
Tomatoes. — A few of these plants may be grown in 
any greenhouse, and will produce a quantity of most 
wholesome fruit if properly managed. But where dower- 
ing and other plants are the main feature of a small 
structure too many Tomato plants should not be grown. 
A few placed in such a position as not to interfere with 
the healthy growth of the other plants are quite permis- 
sible. The back wall of a lean-to house, or against the 
glass end of a span-roofed house towards the north, are 
good positions. The plants will then get the full advan- 
tage of the sunlight, and will not shade other plants in 
the house.
