Water
Water regularly, especially during establishment and dry periods. Allow the soil to dry out slightly between waterings. Avoid waterlogging, as this can lead to root rot.
Reduce watering in cooler months when growth slows.

Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during establishment and dry periods. Allow the soil to dry out slightly between waterings. Avoid waterlogging, as this can lead to root rot.
Reduce watering in cooler months when growth slows.
Pruning is typically not required for Lathyrus rigidus. Deadheading spent flowers can encourage further blooming and maintain a tidier appearance.
If the plant becomes overgrown or leggy, light trimming in late winter or early spring can help maintain shape.
Propagate Lathyrus rigidus by seed. Sow seeds in early spring or autumn. Scarify the seed coat or soak seeds in warm water for 24 hours to improve germination rates.
Young plants can be transplanted when large enough to handle.
Repotting is rarely necessary for Lathyrus rigidus as it is often grown as an annual or short-lived perennial.
If grown in a container and root-bound, repot into a slightly larger container in spring using well-draining soil. Ensure good drainage in the new pot.
