Mildew on clematis can be effectively controlled with a mixture of 900 ml of water, 100 ml of fresh milk and a splash of dishwashing liquid. Spray this solution on the bottom and top of the leaves every 3 days to ward off the fungal infection.

Fresh milk contains useful microorganisms that kill fungal spores. In addition, the lecithin it contains counteracts the disease, while sodium phosphate strengthens the defenses of a clematis. How to use the home remedy correctly:
- Mix 900 ml of water with 100 ml of fresh milk
- Add a splash of detergent for better adhesion to the leaves
