CALENDAR OF OPERATIONS 111 
old plants should have some of the soil removed from 
the roots, and be repotted. 
Perpetual- Flowering Varieties.—The work is very 
much the same as last month. Green-fly and thrips are 
easily killed by fumigating. Red spider will surely appear 
in hot weather, and it is doubtful if any fumigating will 
kill them; the pest must be dislodged by the syringe or 
garden engine. Prepare for housing the pot plants and 
planting up the benches. The sooner the bench plants 
are placed in their positions the better. See that the 
houses and benches are made thoroughly sweet and 
clean before the plants are removed indoors. Give pot 
plants frequent applications of liquid manure, and_ top- 
dressings of an approved chemical fertiliser. 
Pinks.—These are easily propagated by layers and slips. 
The young plants ought to be rooted by the beginning of 
this month, and the seed-pods, if seed is to be saved, will be 
ripening. As soon as the points of the seed-pods become 
brown, they may be gathered ; the husk should be removed, 
and the pods laid out to dry. In ten days or more the seed 
may be removed, and put into packets until it is wanted in 
spring. 
SEPTEMBER 
Border Carnations and Picotees.—Remove the layers 
from the plants this month ; as they were not layered all at 
the same time, those which were layered first should be the 
first to berepotted. The collections should be kept in alpha- 
betical order, the Bizarres and Flakes to be arranged as pre- 
viously advised. The number of layers potted or planted 
out of each variety should be kept entered in a book. New 
varieties intended to be added to the collection should be
