The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of figuring out when it's the best time to plant onions is to use the USDA zone info for Coral Springs.

When to plant:	Up to 7 weeks before last frost.

Since onions are very cold tolerant you can plant them quite a bit earlier in the year than more sensitive plants.

The last month that you can plant onions and expect a good harvest is probably October. You probably don't want to wait any later than that or else your onions may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your onions indoors.
