Gardening techniques for rose protection and disease management

Gardeners utilize natural strategies to protect roses, particularly during the transition to autumn. One effective method involves planting borage (Borago officinalis) near rose bushes. This melliferous plant provides protection and acts as an ally against pests like aphids during the late summer months when roses may be weakened by heat.

To combat common rose diseases such as powdery mildew (oïdium) and black spot (marsonia), experts recommend early intervention. Natural treatments for powdery mildew include spraying a mixture of baking soda and water or diluted milk. To prevent black spot, which thrives in warm, humid conditions, it is essential to remove fallen leaves and plant debris to eliminate fungal overwintering sites. Other preventative measures include using horsetail manure or Bordeaux mixture.
