What Happens When You Place a Tablespoon on Your Plants

Using a tablespoon of various substances on your plants can produce different outcomes—some beneficial and others harmful. Here’s what you might expect based on what you choose to use:

1. Water

Outcome: A tablespoon of water won’t harm your plant but will provide minimal hydration. It may only slightly moisten the top layer of soil, which is generally insufficient for most plants.

2. Coffee Grounds

Outcome: Moderate amounts can enrich the soil with nitrogen, benefiting acid-loving plants like azaleas. However, too much can lead to overly acidic soil, potentially harming the plants.

3. Sugar

Outcome: Not advisable. Sugar can attract pests such as ants and encourage mold growth, creating unhealthy conditions for your plants.

4. Mild Dish Soap

Outcome: A small amount can help control pests like aphids, but excessive use can hinder leaf respiration and sunlight absorption, which may damage the plant.

5. Milk

Outcome: Diluted milk can treat fungal infections like powdery mildew. However, undiluted milk may promote bacterial growth, resulting in odors and unhealthy conditions.

6. Epsom Salt

Outcome: Provides magnesium and sulfur, which can enhance growth, especially in tomatoes and peppers. Use sparingly to avoid salt buildup in the soil.

7. Banana Peel

Outcome: Rich in potassium and phosphorus, banana peels can improve soil quality and promote healthy growth. Make sure to bury them in the soil to prevent attracting pests.
