One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. 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 estimating when it's the best time to plant bellis is to use the USDA zone info for Gridley.

The last month that you can plant bellis and expect a good harvest is probably October. Any later than that and your bellis may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your bellis indoors.
