The idea of placing a tablespoon of various substances on your plants can yield different results—some beneficial, others potentially harmful. Here’s a breakdown of what might happen depending on the substance used:
1. Water
Result: A tablespoon of water won’t harm your plant but is unlikely to provide meaningful hydration. It may only moisten the surface soil slightly, which is generally insufficient for most plants.
2. Coffee Grounds
Result: In moderation, coffee grounds can enrich soil with nitrogen, benefiting acid-loving plants like azaleas and blueberries. However, excessive use can make the soil too acidic and potentially harm the plant.
