If the magnificent leaves of a clematis are covered with mealy-white spots, the fungal infection powdery mildew has struck. Since the use of chemicals is frowned upon in the nature-loving hobby garden, a tried-and-tested household remedy is now being used. You can find out what that is here.
Fight powdery mildew with milk - this is how it works
Beneficial microorganisms cavort in fresh milk, which put an end to the fungal spores. In addition, the contained lecithin 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 squirt of dish soap for better adhesion to the foliage
- Apply the remedy to the undersides and tops of the leaves every 3 days
So that the pretty leaves of the clematis are not marred with limescale, we recommend using collected rainwater or decalcified tap water. Incidentally, UHT milk is unsuitable as a remedy for powdery mildew on clematis, since there are hardly any microorganisms in it.
