Inspect your bushes now, picking off and burning all buds that show indication of infection. Unless this is done now the mites will escape from the buds. To destroy any mites which escape the bushes should be sprayed with lime sulphur. Tlie usual strength is 1 in 15. The best time to' spray is before the flower trusses develop and when the largest leaves are about the size of a shilling.
