Have a Gardening Question?

The Cape Cod Cooperative Extension Horticulture Clinic, staffed by Master Gardeners, handles gardening questions, both general and diagnostic and tests soil samples to determine PH levels.

If you have a gardening question, please submit your question to the Master Gardeners at gardeners@capecod.gov or call the Clinic: (508) 375-6700. Details are important for an accurate answer.

For questions that involve the identification of insects, plants, weeds, diseases or even a mystery problem, include high quality photographs with your submission so we can make a conclusive diagnosis. For pointers on taking high quality diagnostic photos, click here.

For further information on how to gather a sample and how to submit it (at the Barnstable County Cooperative Extension offices) - including drop off location, hours of operation and mailing instructions, please click the buttons below.
