Water
Water sparingly once established, allowing soil to dry out completely between waterings. Young plants may require more frequent watering until well-rooted.
Avoid overwatering, as this species is drought-tolerant and susceptible to root rot.

Watering, pruning, propagation, and repotting details from plant data
Water sparingly once established, allowing soil to dry out completely between waterings. Young plants may require more frequent watering until well-rooted.
Avoid overwatering, as this species is drought-tolerant and susceptible to root rot.
Pruning is usually not required for Chorizanthe biloba. Dead or damaged stems can be removed at any time to maintain a tidy appearance.
Minimal intervention is best to avoid disturbing the plant's natural growth habit and delicate structure.
Propagation is best achieved through seeds, which require stratification. Sow seeds in late autumn or early spring. Germination can be erratic and slow. Cuttings are generally not successful for this species.
Repotting is rarely necessary as Chorizanthe biloba is a small, short-lived perennial. If container-grown, repot in spring only if severely root-bound, using a very gritty, well-draining soil mix.
Handle roots with extreme care.
