When can I plant Pansies in Zone 5a

One of the best tools that we have as gardeners to help us determine our gardening schedule is the 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.

The USDA zone info for Zone 5a can be reviewed to estimate when to plant pansies.


Planting Calendar for Pansies

Frost tolerance for pansies: Very tolerant of frost.

You can plant pansies much earlier in the year because they are one of those plants that can tolerate quite a bit of cold weather.

The earliest that you can plant pansies in Zone 5a 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 pansies and expect a good harvest is probably September. Any later than that and your pansies may not have a chance to grow to maturity. If you are starting your pansies indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Zone 5a. It might get as low as -20°F during the coldest months of winter.

Remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 5a and it changes from year to year. Since half of the time in Zone 5a it frosts late in the year after April 15 be ready to cover your pansies if we have a surprise late frost.
