RWPBC/URI Master Gardener volunteers conduct free soil pH testing as a service to the residents of Rhode Island. The test helps determine soil pH levels and predominant soil texture and provides basic information and recommendations for gradual correction of soil pH and compaction issues.

If you’d like to visit RWPBC after you drop off your sample you may purchase tickets in advance here: https://www.providenceri.gov/botanical-center/.
