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

One way of getting a good idea when you can plant parsley is to look at the USDA zone info for Winters.

Planting Calendar for Parsley

Parsley can survive in some cold which means that you can plant them just a bit earlier in the year than more sensitive plants.

The earliest that you can plant parsley in Winters 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 parsley and expect a good harvest is probably October. Any later than that and your parsley may not have a chance to fully mature. If you are starting your parsley indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date
