Water
Allow soil to dry out completely between waterings. Argemone munita is drought-tolerant once established. Overwatering can lead to root rot, especially in poorly draining soil. Water sparingly during winter dormancy.

Watering, pruning, propagation, and repotting details from plant data
Allow soil to dry out completely between waterings. Argemone munita is drought-tolerant once established. Overwatering can lead to root rot, especially in poorly draining soil. Water sparingly during winter dormancy.
Pruning is typically unnecessary for Argemone munita. If spent flowers or dead foliage are unsightly, they can be removed after flowering to maintain a tidy appearance. Avoid heavy pruning, as it can stress the plant.
Propagate from seed, which often requires stratification. Sow seeds in autumn or early spring in well-draining soil. Germination can be erratic.
Division of established clumps is also possible in spring, but handle with care due to spines.
Repotting is rarely needed as Argemone munita is a perennial that prefers to be undisturbed. If container-grown, repot only when severely root-bound, using a very gritty, well-draining soil mix.
Spring is the best time to repot.
