FAQ About Indoor Plant pH and Acidity Management

Testing the pH level of soil for indoor plants can be done using a commercial soil pH testing kit, pH meter, or by sending a soil sample to a lab. Home testing kits are widely available and usually involve mixing a soil sample with a testing solution that changes color based on the pH. A pH meter gives a digital reading of the soil's acidity or alkalinity. For the most accurate results, take samples from different areas of the pot and at various depths.
