Help Desk

The Loudoun County Master Gardener Volunteers are here to help you with your gardening questions. Is something eating your hostas? Does your tree look sick? When is the best time to fertilize your lawn? Are you interested in constructing a compost pile? Is a strange weed overrunning your vegetable bed? We’re here to advise and help!

Due to the COVID 19 health crisis, the physical Help Desk is not being manned by Extension Master Gardener volunteers (as of 3/17/20).  While we are not accepting walk-in clients to drop off samples for diagnosis, we continue to respond to your digital requests!

To request help with a plant/insect problem, please fill out the Help Desk Request Form or send an email directly to loudounmg@vt.edu.  Include a minimum of 3 photos:  plant part affected, good part of the plant, and where it is planted.  See document for photo tips: Guidance for Submitting Good Digital Photos.

We will update the website when we are back to business hours.  Please allow a minimum of 5 days for a response.

Brochures on plant care, upcoming Master Gardener Events and Soil Test Kits continue to be available at the Extension Office.

Help Us Help You

Here are a few tips to help us provide you with the right information:

  • If you need a plant identified, please bring in a sample large enough to determine the size and growth habit. Please bring in an entire stem or branch, not just a leaf.
  • If you suspect insect or disease, please bring in a sample showing both the problem area and some healthy growth (if any). Again an entire branch or stem will help us determine what is going on. We would appreciate that your sample be in a bag so as not to potentially contaminate the office.
  • Clear digital photos are great for email identification, but please keep the size reasonable to reduce download time.

We may have to do some research to come up with the right answer to your problem. If necessary we will contact you usually within 1-2 days.
