FAQ About Indoor Plant pH and Acidity Management
How can I raise the pH level of soil for indoor plants?
To raise the pH level and make the soil more alkaline, you can add lime, wood ash, or crushed eggshells. Lime (calcium carbonate) is typically used and can be mixed into the soil. It gradually raises the pH over time. Wood ash can also be sprinkled on the soil surface as it contains potassium and calcium carbonate. Always re-test the pH after adjusting the soil to ensure the desired level is reached.
