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

The first chance to plant anemone in Ontario should be estimated by checking out the USDA zone info.

Planting Calendar for Anemone

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

Anemone can survive in moderate cold which means that you can plant them a bit earlier in the year than other frost tender plants.

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

The last month that you can plant anemone and expect a good harvest is probably October. You probably don't want to wait any later than that or else your anemone may not have a chance to grow to maturity. Starting your anemone indoors is a great way to get them started a few weeks earlier.

Last Frost Date

The average date of last frost is January 31 in Ontario. You can expect an average low temperature of 30°F in the coldest months of winter.

It's important to remember that the actual date of last frost is an average because it is based on the USDA zone info for Ontario and it changes from year to year. Half of the time in Ontario there is a last frost after January 31 so make sure that you are ready to cover your anemone if you have a surprise late frost.
