When can I plant Arctotis in Zone 1b

Before planting it is a good idea to find our USDA Zone info to estimate our garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

The earliest that you can plant arctotis in Zone 1b should be estimated by reviewing the USDA zone info.

The last month that you can plant arctotis and expect a good harvest is probably July. If you wait any later than that and your arctotis may not have a chance to really do well. Starting your arctotis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is June 15 in Zone 1b. We should expect an average low temperature of -55°F in the coldest months of winter.

Remember that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 1b and it will vary from year to year. Half of the time in Zone 1b it frosts late in the year after June 15 so make sure that you are ready to protect your arctotis in the event of a surprise late frost.
