One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of making a decision about when it's the best time to plant arctotis is to refer to the USDA zone info for Jackson.

Since arctotis are one of those plants that can tolerate a little bit of cold weather you can plant them just a bit earlier in the year than other plants that might not handle the cold.

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