When can I plant Parsnip in Zone 5a

One of the best tools that we have as gardeners to help us estimate 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.

In Zone 5a you can determine when you can plant parsnip by referring to the USDA zone info.

The last month that you can plant parsnip and expect a good harvest is probably September. Any later than that and your parsnip may not have a chance to fully mature. Starting your parsnip indoors is a great way to get them started a little bit earlier.

Last Frost Date

Keep in mind that USDA zone info for Zone 5a is not always accurate and our actual date of last frost changes from year to year. Since half of the time in Zone 5a we get surprised by a frost after April 15 be ready to cover your parsnip in the event of a surprise late frost.
