How and where to get garden soil testing in every state

March 29, 2022

If you are looking for soil testing near me – this is the place. With only a few exceptions every US state has a university based extension program that operates a soil lab. These soil testing labs can used by both commercial growers and farmers and home gardeners. Most tests are very affordable (~$20 or less) and there are instructions for how to collect and package the samples on each website.

It is common for the service to also include fertilizer or other amendment recommendations based on the test results and the crop or plants you want to grow. These are typically customized by the state (for example, here in New England, there are special requests for those interested in growing blueberries – a popular crop in the region). Your extension may offer other regionally appropriate options.

Knowing what is going on in the other half of your garden is imperative to your garden design success. In this post – Soil Compost Mulch: Restore your soil (and feed your plants) – How to Mulch and Compost a climate change solution- I talk about how these are the first things to take note of and work with as your seek to improve your landscape and build a garden. It is a great place to start.
