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

Last Frost Date

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