When can I plant Daylily in Zone 2a

One of the first steps we take when we are estimating our gardening schedule is find our USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

One way of estimating when you can plant daylily is to examine the USDA zone info for Zone 2a.

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

The last month that you can plant daylily and expect a good harvest is probably August. You probably don't want to wait any later than that or else your daylily may not have a chance to fully mature. Starting your daylily indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 2a the average date of last frost happens on May 15. In the coldest months of winter we should expect an average low temperature of -50°F.

It's important to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 2a and it will vary from year to year. Since half of the time in Zone 2a it frosts late in the year after May 15 be ready to protect your daylily if we have a surprise late frost.
