Just guessing but I would think you go to your phone book and look under the government listings in the blue pages then search for County Extension Service. Give them a call and pose your question to them. You might also google Master Gardener, xyz county Z(or xyz state)

Here ya go!!

Here is a link that might be useful: Connecticut Master Gardener program

I couldn't get anything at that link. Might have been the time of day.
If you go to this one you will need to choose a general category of agriculture, etc., then a specific category of Master Gardener. That should get you to the information you need.
