Curled Parsley

Parsley thrives in well-draining, nutrient-rich soil with a pH range of 6.0 to 7.0. The soil should be moist but not waterlogged, as parsley can be prone to root rot in excessively wet conditions. Parsley prefers partial shade to full sun, but in hot summer climates, it can benefit from some afternoon shade to prevent wilting. Sow parsley seeds in early spring or fall, as it's a biennial plant that typically goes to seed in its second year.

To plant parsley seeds, first, prepare a well-draining soil mix in a pot or garden bed. Sow the seeds about ¼ inch deep and keep the soil moist but not waterlogged until germination has occurred (up to 3 weeks). When sowing outdoors, we have found that interplanting with fast-maturing radishes improves germination.

Parsley is best transplanted in early spring or fall to a sunny or partly shady location with well-draining soil. Dig a hole deep enough for the root ball, gently remove the plant from its container or soil, and place it in the hole. Backfill with soil, tamp down gently, and water thoroughly. Keep the soil moist but not waterlogged and protect the young plant from harsh sun or wind until it's established.

Diseases & Other Problems

To harvest parsley, wait until the plant has grown to at least 6 inches tall and has developed several sets of leaves. Cut the outer leaves or entire stems near the base of the plant, leaving a few inches of stem attached. Use the leaves immediately or store them in the refrigerator for up to a week by wrapping them in a damp paper towel and placing them in a plastic bag. To store parsley long-term, dry it by tying a bundle of stems together and hanging it upside down in a dry, well-ventilated area for several weeks. Once dry, remove the leaves from the stems and store them in an airtight container in a cool, dry place for up to a year.

CONSIDERATIONS:

Parsley is a biennial plant that produces flowers in the second year of growth. In cold climates, plants should be mulched with straw or dug and brought indoors to protect them during the coldest months. Once replanted in the second year, plants will begin to flower. Parsley is an outbreeding plant and cross-pollination occurs freely between different varieties of both rooted and unrooted types. It is therefore necessary to plant just one variety or to cage different varieties to prevent pollen contamination. The recommended isolation distance for parsley is 0.5-3 miles.

HARVESTING SEED:

Parsley seed heads shatter easily and may need to be harvested daily to maximize seed yield. Place the mature heads in a paper bag to finish drying, then rub the heads to release the seed. Winnow to remove chaff and store in a cool, dry, and dark place.

SEED LONGETIVITY:

Parsley seeds can remain viable for up to three years when stored properly.
