🌿 What Is Powdery Mildew and Why It’s a Problem

✅ Step 1: Prune and Isolate Infected Plants

Cut off all infected parts of the plant. Dispose of the leaves far from your garden to prevent further spread. If the whole plant is covered, isolate it.

✅ Step 2: Apply Homemade Baking Soda Spray

This is the core of the remedy. Here’s the recipe:

Baking Soda Spray Recipe:

• 1 tbsp baking soda
• 1 tsp mild liquid soap (like Castile)
• 1 gallon water

Spray the mixture on all surfaces of the plant every 3 days. Baking soda creates an alkaline environment where fungus can’t survive.

✅ Step 3: Improve Air Circulation and Sunlight

• Space out your plants
• Trim nearby shrubs
• Ensure 4-6 hours of sunlight

This reduces the damp environment mildew thrives in.

✅ Step 4: Use Neem Oil as a Follow-Up Treatment

Neem oil is both antifungal and insecticidal. Apply it once a week after the baking soda sprays to kill remaining spores and prevent new growth
