One of the important differences that will distinguish this feature from other general "trip advisor" or "yellow pages" sites is the input from each of us as gardeners.
Please add your feedback for the businesses you've patronized and the public gardens and parks you have visited. It helps other gardeners and the business or organization.
For smaller businesses and organizations, this type of "word of mouth" is their only form of advertising. And for businesses of any size, unsolicited testimonials are priceless - they can't buy that type of good will.
You can narrow these down to a particular category (garden center/nursery, or public gardens, etc.) You can also plug in your ZIP and specify a radius (especially helpful if you live near the state line and want to see everything in your immediate area.)
If your favorite nursery or park/garden isn't listed yet, let us know and we'll add it, or start the entry and add what you know (we'll fill in the blanks.)
