Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Rough chervil prefers consistently moist soil but can tolerate occasional dryness once established. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.
In hot, dry periods, more frequent watering may be necessary.
Prune Rough chervil to maintain shape and encourage bushier growth. Deadhead spent flower stalks to prevent excessive self-seeding and prolong the blooming period.
Cut back plants in late autumn or early spring to remove dead or damaged foliage and promote new growth.
Rough chervil is easily propagated by seed. Sow seeds directly outdoors in early spring or autumn.
It can also be propagated by division in spring or autumn, though it is generally best to let it self-seed for a continuous supply.
Repotting is rarely necessary for Rough chervil, as it is often grown as an annual or biennial and can self-seed readily. If grown in a container and it becomes root-bound, repot in spring into a slightly larger pot with fresh potting mix.
