"THE BEST IN ROSES" 33 


PEST CONTROL 
Roses, like all other plants, have pests and diseases 
which may be controlled with a little effort.. The most 
common of the diseases are mildew, rust, and in some 
sections, blackspot. In a warm climate dusting lightly 
once a week with a mixture of nine parts of dusting 
sulphur to one part of arsenate of lead will control 
these diseases. 
In a cool climate excellent results have been obtained 
by spraying every ten days with one bottle cap of 
Greenol and one tablespoon of summer oil per gallon 
of water. Whether you dust or spray, do it con- 
sistently every week or ten days during the growing 
season. The pyrethrum or rotenone sprays may be 
added to the Greenol summer oil combination for con- 
trol of aphids or may be used separately as desired. 
A clean-up spray after pruning consisting of ten 
tablespoons of either Bordeaux or Lime Sulphur to one 
gallon of water is very effective to clean up the mildew 
and rust spores. Old leaves should be picked up and 
burned. 
CUTTING ROSES 
When cutting roses, leave three or four buds (above 
each leaf is a bud) of the new wood. Cut to an outside 
bud so as to keep the plant open which will help to 
prevent mildew and rust. 
Cut roses either late in the evining or early morning. 
Split or mash stems and plunge immediately in deep 
water up to the neck. Allow to stand for several 
hours to absorb water. Single roses should be cut in 
tight bud when color is just beginning to show between 
opening sepals; double roses as they start to unfurl.
