Parsnips Parsnips should be planted in early spring, about the same time as peas and radishes. Like carrots, they require a deeply tilled, well-prepared soil, raded smooth of rocks and clods. Soaking the seeds overnight or treating with boiling water before planting may help. You can start the seeds indoors between moist sheets of paper towels.
Presprouted seeds have a better chance of survival.
When the tiny white roots of the sprouted seeds are about inch long, they're ready to plant. Be careful not to break the small roots or allow the seeds to dry out. Bigger Parsnips A trick for growing monster parsnips is to plant them in conical holes. Drive a crowbar into the soil to a depth of about 2 feet, rotating the bar in a circular motion until the hole is about 6 inches across the top. Fill the hole with a mixture of sand, peat moss, and sifted soil, leaving a slight depression at the top of the hole.
