The best way to rid a plant of these enemies of roses which “eat them alive,” is to hand-pick them, throwing them into a can of kerosene.
There is a patent preparation which is good. Write your dealer for information as to this.
Treat for other insects as you have already learned.
If your parents think you may be trusted to handle a poison, spray in the early Spring with “Bordeaux Arsenate of Lead” to prevent mildew and rust. In summer, use Flowers of Sulphur.

Prune rose bushes in the early Spring, just when the plants begin to show green, which means that their sap is beginning to flow. Use pruning for cutting the stems back.
Remember these principal rules:
1. Hybrid Perpetual Roses should be cut back about two feet from the ground.
