What Happens When You Put a Tablespoon of Different Substances on Your Plants?

4. Mild Dish Soap

Result: A small amount of diluted dish soap may help control pests such as aphids and spider mites. However, excessive use can damage leaves by interfering with their ability to absorb sunlight and exchange gases.

5. Milk

Result: Properly diluted milk can help manage fungal diseases such as powdery mildew. Undiluted milk, however, may promote bacterial growth, resulting in unpleasant odors and unhealthy growing conditions.

6. Epsom Salt

Result: Epsom salt provides magnesium and sulfur, nutrients that can support plant growth, particularly in tomatoes and peppers. Use it sparingly to avoid salt buildup in the soil.

7. Banana Peel

Result: Banana peels are rich in potassium and phosphorus, nutrients that can enhance soil quality and support healthy plant development. Burying them in the soil helps prevent attracting pests.

8. Eggshells

Result: Crushed eggshells add calcium to the soil, which may help prevent blossom-end rot in tomatoes and other calcium-sensitive plants. Because they decompose slowly, their benefits are released gradually over time.

9. Fish Tank Water
