TRY THIS REMEDY FOR ROSE MILDEW

Mildew is one of the most troublesome diseases of the rose. It consists of a white or greyish powdery coating on the leaves and buds. Not only does it render the trees unsightly, but they are weakened, and then flowering is adversely affected. The simplest cure for rose mildew is to dust the affected leaves and buds with flowers of sulphur. It is essential that this should be done when the leaves are damp. Early in the morning when the foliage is still wet with dew is a good time. It is not always possible to do this, however. Often during dry weather the dews are not sufficiently heavy to moisten the foliage. In this case spray thoroughly with a liver of sulphur solution. Even more effective is one of the lime-sulphur or ammonium polysulphide sprays. The amateur gardener who is troubled with rose mildew should obtain one or other of these spray fluids. Dilute according Ito the manufacturers’ instructions and spray the bushes well. In this way the mildew will be checked.
