How To Prevent Mildew on Roses

Everybody loves a rose bush. They create a beautiful sight in your yard, and the flowers can be used to create a beautiful bouquet. If your roses have mildew on them, it can ruin the beauty of the flower. Mildew is a fungal disease, which appears as white powder on young leaves that causes the leaves to wrinkle. It can then continue to spread and develop into spore-bearing fungus on the foliage, stems, and other parts of the rose.

The mildew spreads most rapidly when the weather is hot and dry during the day, and cool and moist at night. The spores of the mildew are dormant until they get enough moisture to germinate. This mostly occurs in damp and shady gardens where there is poor air circulation and the plants are stressed due to overcrowding.

Follow these 4 tips to help ensure your roses do not get mildew.

  1. Plant roses in a place that receives at least six hours of sunlight a day. Plant the bushes at least 4 feet apart and prune them regularly to help with air circulation.
  2. Water the soil around the roses in the morning rather than watering from the top to keep the leaves and stems dry.
  3. Regularly check the roses for signs of mildew. If any young leaves are starting to curl, remove them and check to make sure the mildew did not spread.
  4. Mix 2 teaspoons of baking soda and ½ a teaspoon of liquid dish soap together in 2 quarts of water and spray it on the plants at least once a week to prevent the growth of mildew.
