One of the best tools that you have as gardeners to help us figure out 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 figuring out when it's possible to plant arctotis is to use the USDA zone info for Germantown.

Planting Calendar for Arctotis

Frost tolerance for arctotis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since arctotis do well in moderate cold you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant arctotis in Germantown is February. However, you really should wait until March if you don't want to take any chances.

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. Starting your arctotis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average all chance of frost has passed is on April 15 in Germantown. In the coldest months of winter you should expect an average low temperature of -20°F.

Keep in mind that the actual date of last frost is not always accurate because it is based on the USDA zone info for Germantown and it can change quite a bit from year to year. Half of the time in Germantown there is a last frost after April 15 so always be ready to cover your arctotis if you have a late frost.
