Summary of the requirements for submitting a garden for the 2026 GNGT:

1. ✦You must be the owner of the garden you are submitting, and you must accept a Waiver of Liability (this is required by the tour sponsors). You will see that waiver on the next page.
   

2. ✦The garden must be in San Mateo County or Santa Clara County.
   

3. ✦At least 70% of the garden areas on tour must be California Native plants. You can submit the entire garden, or only the part that is predominantly native (e.g. front or back).
   

4. ✦The garden must not feature invasive non-native plants (see our Don’t Plant a Pest page).
   

5. ✦We must have your email address, at least for the initial tour-related communication. You can designate another person, e.g. your garden designer, to handle most communications.
   

6. ✦On tour day, a responsible adult must be on site during tour hours. In most cases, owners are available to answer questions (and receive compliments).
   

7. ✦We ask you to recruit your own helpers (docents, greeters) for the tour day. If you can't, the tour committee will help.

1. ✦If your garden was featured on a previous tour, you will be redirected to a simplified submission page, where you will be able to submit your garden with a single click.
   

2. ✦If you are submitting a new garden, you will be redirected to a page which will ask you to provide information about the garden. That form is quite long, but you will be able to save a partial submission and return to it later if you need more time.

All personal information entered on the Garden Submission forms will be kept private. We do not share emails or phone numbers with anyone.
