midsummer. Thoroughness of application is far more 
important than the quantity of material used. 
The under side of the foliage must be reached because it 
is there that the tiny spores of black-spot, just like tiny 
seeds, begin to germinate in the presence of moisture. 
Hence the paramount importance of seeing that Rose 
foliage is covered with an active fungicide during rainy 
periods. 
SLUGS AND WORMS. These chewing pests are killed 
with the lead arsenate contact of most all commercial 
mixtures. 
APHIS OR GREEN FLY. Various colored aphis suck 
the juice from the leaves and must be killed by smothering 
their bodies with a contact spray such as Black-Leaf 40, 
Red Arrow, or Ever Green spray. While, they can easily 
be seen, still they are not nearly as injurious as the in¬ 
visible spores of black-spot. 
Red spider, leaf hoppers, thrips, and other almost 
microscopic insects are also killed by contact sprays, or 
by the fine dusting sulphur in the Pomo-Green mixture. 
ROSE BUGS AND CHAFER. A very familiar pest 
whose appearance is, fortunately, limited to about two or 
three weeks in June. Troublesome in some localities, but 
never present in others. A very stupid insect feeding on 
the petals of white and light-colored roses and must be 
picked off the bloom and drowned in kerosene. There is 
no other remedy. 
Spraying Dormant Plants 
Give your Rose plants a clean bill of health late in the 
fall before protecting for the winter and again early in 
spring before growth begins. Use either lime sulphate or 
Bordeaux mixture at recommended dormant strength. 
The reader should not allow the foregoing to discourage 
him, as with a well-prepared soil, strong, vigorous plants 
to start with, and a little watchfulness to nip in the bud 
any attack of insect or disease, he will have little to fear. 
It is the indifferent, indolent grower, and the planter of 
greenhouse-grown Roses that have been raised among 
tropical conditions, whose plants suffer severely. 
Detailed information about how to plant Roses properly 
is sent with each order. 
After roots have been spread out and the hole partly 
filled with soil, be sure to tramp firm. 
Winter protection is thoroughly explained in a circular
