Growing Parsley in Illinois
Illinois provides an ideal environment for growing parsley, with its relatively mild summers and cold winters. By taking advantage of the spring and fall growing seasons, gardeners can enjoy this herb in their kitchens nearly year-round.
Best Time to Plant
In Illinois, you should plant parsley in early spring (late April to May) once the danger of frost has passed. You can also plant a fall crop in late summer (August) for a harvest that lasts into the early winter months. Starting seeds indoors 6-8 weeks before the last frost date will give your parsley a head start in the growing season. Illinois’ fall season is also long enough to plant a second crop.
Soil and Watering Needs
Parsley prefers well-draining, fertile soil. Before planting, amend the soil with compost to improve its nutrient content and water retention. Water parsley consistently, ensuring the soil remains moist but not soggy. In Illinois, the consistent rain helps reduce the need for frequent watering, but during dry spells, make sure to keep the soil damp.
Sunlight and Temperature
Parsley grows best in full sun, but in Illinois, where summers can sometimes be hot and humid, partial shade can be beneficial during the peak summer months. The ideal temperature range for parsley is between 60-70°F, making Illinois’ spring and fall seasons perfect for this herb. Too much heat can cause parsley to bolt, so avoid planting it during the hottest part of the summer.
Harvesting Tips
Begin harvesting parsley when the plant reaches about 6-8 inches tall. Regularly trim the outer leaves to encourage new growth. If planted in the fall, parsley can often survive the first few frosts with some protection, allowing you to extend the harvest into late fall. Be sure to mulch around the plants to protect them from cold snaps.
