Collin County Master Gardeners welcome inquiries about your specific gardening issues or about any of the programs and services we offer the community.

• Have a gardening question? To submit a question to our Help Desk, click here or call the Extension Office at (972) 548-4232 or Metro (972) 424-1460, x 4232. The Master Gardener Help Desk is not staffed 24 hours per day, so please allow a reasonable amount of time for us to research and respond to your inquiry.
  • You are also welcome to visit the Collin County office of the Texas AgriLife Extension Service in McKinney, especially if you need to show us a sample of the pest or plant disease you wish to identify. Office hours are 8:00 a.m. to 4:30 p.m., Monday through Friday. Please call ahead to be certain that a Master Gardener or the horticulture agent is available.
