Soil pH Testing

Saturday, April 8 at 10:00am to 2:00pm

The URI Master Gardener Soil Testing service is free of charge.  You bring us a sample of your soil and we test its pH (acidity/alkalinity) and evaluate its texture and content.  Much of the soil in our region is more acidic than vegetable and ornamental plants generally need to get the nutrition they need from the soil.  We provide recommendations for the gradual improvement of your soil’s pH and health.

How to Take a Soil pH Sample:

You will want to collect the samples of soil at the plant or lawn root zone (around 6″ deep). You should be gathering about a 1/2 cup amount from several sites within the same area to be tested. Mix them together, allow the soil to dry. Next place 1 cup of the mix in a paper bag or clean container and label it. Collect separate samples from different areas on your property such as vegetable gardens, lawns and flower gardens. Bring all the samples to the soil testing location.

We reserve the right to cancel within one week of event if staffing by URI Master Gardeners is not available.
