Find Your Planting Zone

Enter your address here to find your planting zone. Knowing your zone will help you make better decisions in your garden and allow you to take advantage of our zone-specific planting charts and calendars. The US Department of Agriculture created these zones based on a crop’s hardiness or ability to succeed in certain weather conditions. This information is important for choosing varieties that will do well in your climate.

Get to Know Your Microclimate

Successful growers learn how conditions in their location differ from general guidelines and modify them to fit their situation. Therefore, we encourage you to monitor local temperatures and get to know your microclimate. If you live in a valley or on top of a hill, your microclimate could vary from your neighbors just a few miles away.


As a seed company based out of San Diego, CA, we emphasize resources and specialize in acclimating seeds to the range of microclimates in our region so that growers can be as successful as possible. We select varieties for traits, such as heat tolerance, that are exceedingly important to growers along the West Coast and across the southern band of the continental US. Our seeds are 100% viable for growers in other zones. You can find planting guidelines for all zones within the information section of each product page. When choosing crops to grow in Zones 5–8, ensuring they mature during your frost-free days is the most important consideration. Some of our San Diego Seed Company varieties have long days to maturity because the growing season in parts of Zone 10 is 365 days!
