soil pH testing for blueberries

Asked January 19, 2021, 7:44 PM EST

Does Linn Co Extension offer soil pH testing? If so, I'm interested in the details of how that works. If not, what type of soil pH test kit is recommended for a home blueberry patch? I've looked at what is available online and I'm a little overwhelmed by the many choices and the reviews.

Thanks for reaching out. Generally we don't recommend home soil tests since they are often not very accurate. Currently OSU is on limited operations and staff are working from home. Under average circumstances, Master Gardener volunteer programs based on Corvallis or Tangent can do a basic pH test on your soil/substrate. If your soil test can wait and a pH test is what you are seeking I suggest contacting us again when risk in our county drops from "Extreme" to "High" or lower.

If you want to get your soil tested sooner, or need other components of your soil tested like nutrients or potential contaminants, this publication has a list of Oregon labs that offer these services for a fee. You'll want to request recommendations specifically for blueberries: https://catalog.extension.oregonstate.edu/em8677

To get the most accurate results, please collect your soil sample from several inches below the surface, to avoid organic matter like roots, grass and mulch. You can find detailed directions here: https://catalog.extension.oregonstate.edu/ec628

I hope this helps you decide what option best meets your needs. Please reach out if I can assist further.
