Wild parsnip prefers consistent moisture but can tolerate some dryness once established. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering in cooler months, allowing the soil to dry out slightly between applications.

Pruning is typically not required for wild parsnip unless you wish to prevent self-seeding. Removing flower stalks before they go to seed will significantly reduce the plant's ability to spread.

Otherwise, prune away any dead or damaged foliage in late winter or early spring.

Wild parsnip is easily propagated by seed. Sow seeds directly outdoors in early spring or fall, as they benefit from stratification.

Seedlings can also be transplanted, but take care as they develop a taproot and dislike disturbance.

Repotting is generally not applicable as wild parsnip is a biennial or short-lived perennial grown for its roots or allowed to naturalize. If starting seedlings in containers, transplant them to their final location when they are large enough to handle, ideally before their taproot becomes too established.
