When can I plant Saxifraga in Zone 2a

The USDA Zone info is a great tool for gardeners to help us determine our gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

A way of making a decision about when it's the best time to plant saxifraga is to examine the USDA zone info for Zone 2a.

The earliest that you can plant saxifraga in Zone 2a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant saxifraga and expect a good harvest is probably August. You probably don't want to wait any later than that or else your saxifraga may not have a chance to really do well. You can get started a little bit earlier by starting your saxifraga indoors.

Last Frost Date

On average the last frost is on May 15 in Zone 2a. We can expect an average low temperature of -50°F in the coldest months of winter.

Since the USDA zone info for Zone 2a is an average our actual date of last frost is different every year. Half of the time in Zone 2a we get a frost after May 15 so make sure that you are prepared to protect your saxifraga if we have one of those late frosts.
