1. Baking Soda Solution
Why It Works:
Baking soda, or sodium bicarbonate, is a versatile ingredient with antifungal properties. It works by altering the pH of the plant surface, making it less hospitable to fungi.
How to Prepare and Use:
- Ingredients: 1 tablespoon baking soda, 1 quart water, 1-2 drops of dish soap.
- Instructions: Dissolve the baking soda in water and add a few drops of dish soap to help the solution adhere to plant surfaces. Pour the mixture into a spray bottle and apply it to the affected areas of your plants, focusing on spots with powdery mildew or other fungal issues.
- Application Tips: Spray the solution every 7-14 days, or as needed, to prevent and control mildew. Avoid applying during the hottest part of the day to prevent leaf burn.
Benefits:
- Easy to Make: Uses common household ingredients.
- Cost-Effective: Affordable solution for regular use.
2. Garlic Spray
Why It Works:
Garlic has natural antifungal and antibacterial properties, making it an effective remedy for various plant diseases. Its strong odor helps repel pests and pathogens.
How to Prepare and Use:
- Ingredients: 2 cloves garlic, 1 quart water.
- Instructions: Blend the garlic cloves with water until smooth, then strain the mixture to remove solid bits. Pour the garlic-infused water into a spray bottle and apply it to the plants.
- Application Tips: Use garlic spray every 7-10 days, especially after rain or watering. Be cautious when applying near sensitive plants, as the strong garlic odor may cause some plants to react negatively.
Benefits:
- Natural Repellent: Acts as both a fungicide and pest repellent.
- Effective: Useful for a variety of fungal infections.
3. Milk Spray
Why It Works:
Milk contains proteins and fats that can help combat fungal infections, particularly powdery mildew. The proteins in milk can create a protective barrier on plant surfaces.
How to Prepare and Use:
- Ingredients: 1 cup milk, 2 cups water.
- Instructions: Dilute the milk in water and pour the mixture into a spray bottle. Apply it to the plants, focusing on areas affected by powdery mildew.
- Application Tips: Apply the milk solution every 7-10 days, or after rainfall. It is best used on a sunny day, as sunlight helps the milk to dry and form a protective layer.
Benefits:
- Readily Available: Milk is a common household item.
- Protective Layer: Forms a barrier against fungal spores.
4. Vinegar Solution
Why It Works:
Vinegar is an acid, and its low pH can help inhibit the growth of fungi. It is effective against a variety of fungal diseases, including molds and mildew.
How to Prepare and Use:
- Ingredients: 1 part vinegar, 3 parts water.
- Instructions: Mix the vinegar and water in a spray bottle. Apply the solution to the affected areas of your plants, ensuring thorough coverage.
- Application Tips: Use vinegar solution every 7 days or after rain. Avoid using too much vinegar, as it can potentially harm plants with excessive acidity.
Benefits:
- Versatile: Effective against multiple types of fungal infections.
- Easy to Use: Simple preparation with common kitchen ingredients.
5. Neem Oil
Why It Works:
Neem oil is derived from the seeds of the neem tree and contains compounds with antifungal, antibacterial, and insecticidal properties. It is effective against a wide range of fungal diseases.
How to Prepare and Use:
- Ingredients: 2 tablespoons neem oil, 1 quart water, 1-2 drops of dish soap.
- Instructions: Mix the neem oil with water and dish soap in a spray bottle. Shake well to combine and apply the solution to the plants.
- Application Tips: Apply neem oil every 7-14 days, or after heavy rain. Neem oil can also be used as a preventive measure, not just for treating existing problems.
Benefits:
- Broad Spectrum: Effective against various fungal and pest issues.
- Natural: Safe for use on organic gardens.
6. Pepper Spray
Why It Works:
Cayenne pepper contains capsaicin, which has antifungal and antibacterial properties. The spiciness can deter fungi and pests from attacking your plants.
How to Prepare and Use:

- Instructions: Blend the cayenne pepper with water, strain to remove solid particles, and pour the solution into a spray bottle. Apply to affected plant areas.

- Dual Function: Acts as both a fungicide and pest deterrent.
- Effective: Useful for various fungal infections and garden pests.
7. Epsom Salt Solution
Why It Works:
Epsom salt, or magnesium sulfate, can enhance plant health and reduce susceptibility to fungal diseases. Magnesium helps strengthen plant tissues and boosts resistance to infections.
How to Prepare and Use:
- Ingredients: 2 tablespoons Epsom salt, 1 gallon water.
