About GardenFacts

GardenFacts turns official US climate and plant hardiness records into plain pages that answer what home gardeners ask: which hardiness zone they are in, when frost usually ends and starts again, and when to plant and expect to harvest common vegetables.

GardenFacts is published by Humblebee. We do not sell seeds, plants, fertilizer or garden products, we take no payment from nurseries or brands, and nobody pays us to change what a page says. We are not affiliated with USDA, NOAA, Oregon State University, Colorado State University or any government agency.

Found a mistake? Every page lists its sources, so you can check them yourself. We fix errors as soon as we confirm them.
