Thank you for your question. The most accurate PH test for your garden is through the NCDA&CS. Come to the office at 721 Foster Street, Durham. Our office hours are 8:30 am to 5:00 pm. You will pick up a box/boxes, fill the box with soil, and return to the office. We will send it to Raleigh for testing at their lab. Our courier goes to Raleigh once a week (usually on Thursday morning). This is currently a free service. You will get your results by email.

Please contact me if you have any more questions.
