Place a Tablespoon on Any Plant at Home: What to Expect | July 20, 2025

The idea of placing a tablespoon of various substances on your plants can yield different results—some beneficial and others potentially harmful. Here’s a breakdown of what might happen based on what you use:

1. Water
Result: A tablespoon of water is unlikely to harm your plant but won’t provide substantial hydration. It may only slightly moisten the surface soil, which is generally insufficient for most plants.
2. Coffee Grounds
Result: Moderate amounts can enrich soil with nitrogen, benefiting acid-loving plants like azaleas. However, excessive use can lead to overly acidic soil, which could harm the plants.
3. Sugar
Result: Not recommended. Sugar can attract pests like ants and promote mold growth, leading to unhealthy conditions for your plants.
4. Mild Dish Soap
Result: A small amount can help control pests like aphids, but too much can interfere with leaf respiration and sunlight absorption, potentially damaging the plant.
5. Milk
Result: Can treat fungal infections like powdery mildew if diluted properly. However, undiluted milk may promote bacteria growth, leading to odors and unhealthy conditions.
