Powdery mildew is a common fungal disease that affects a wide range of plants, characterized by white, powdery spots on leaves and stems. Each year gardeners all around the world are looking for ways to win with this desease. We can always buy commercial fungicides, but more often than not we’re looking for organic solutions, so we don’t add any unnecessary chemicals to our veggies. Managing powdery mildew organically involves several strategies which will be shown below.
Before we show you how to fight powdery mildew on your plants, first let’s talk about how to prevent it from appearing in your garden. Sometimes simple practices can help you enjoy your summer worry free.
Choose Resistant Varieties: Select plant varieties that are resistant to powdery mildew.
Proper Spacing: Ensure adequate spacing between plants to improve air circulation, which helps reduce humidity levels around plants.
Watering Practices: Water plants at the base rather than from above to avoid wetting the foliage. Early morning watering is best to allow leaves to dry out during the day.
Pruning: Regularly prune to remove infected leaves and improve air circulation within the plant canopy.
Sun: Locate plants in proper sunlight according to their needs.
Fertilization: Because new growth tends to be more susceptible, be careful to not over-fertilize and cause a rush of new foliage.
Remove Infected Plant Material: Dispose of any infected plant parts in the trash, not the compost pile, to prevent the spread of the fungus.
Clean Tools: Regularly sanitize gardening tools to avoid spreading the disease to healthy plants.
How to get rid of powdery mildew organic ways
Neem oil spray
Neem oil is a vegetable oil pressed from the fruits and seeds of the neem, a tree which is indigenous to the India. It is effective against a variety of fungal diseases, including powdery mildew.
Mix 2-3 tablespoons of neem oil with a gallon of water and a few drops of liquid soap (to act as an emulsifier). Spray thoroughly on affected plants.
Baking soda for powdery mildew
Baking soda is such a marvellous product, it can be used in every area of our lives. To fight with powdery mildew you need to mix 1 tablespoon of baking soda, 1/2 teaspoon of liquid soap (not detergent), and 1 gallon of water. Spray on the affected plants weekly.
Milk spray for powdery mildew
Dilute milk with water at a 1:9 ratio (1 part milk to 9 parts water) and spray on the leaves. This can be effective due to the natural fungicidal properties of milk.
Potassium bicarbonate for powdery mildew
Similar to baking soda but often more effective. Use 1 tablespoon per gallon of water, and spray on affected plants.
Fighting powdery mildew organically is not only better for your plants but also for the environment. By adopting resistant plant varieties, practicing good garden hygiene, and using natural sprays and biological controls, you can keep this fungal foe at bay.
