Gardening Helplines

Trained Master Gardeners are available to answer your gardening questions. When a question requires research the caller’s name and number is taken and the person is contacted after the correct answer is determined. Walk-ins are welcome. Sometimes it is very helpful when the trained Master Gardener can see the plant and pests in person.
