Water regularly, especially during dry spells, to maintain consistently moist soil. Avoid waterlogged conditions, which can lead to root rot. Deep watering encourages a stronger root system.

Reduce watering in cooler months when growth slows.

Deadhead spent flowers regularly to encourage further blooming and prevent self-seeding if not desired. In late autumn, after flowering, cut back the dead stems to about 15 cm from the ground.

This helps prevent disease overwintering.

Propagate by seeds sown directly in the garden in late spring or early summer, or start indoors 6-8 weeks before the last frost. Seeds germinate best with light and consistent moisture.

It can also be propagated by division in spring.

Biennial hollyhocks are typically grown as annuals or biennials and are not usually repotted. If grown in pots for overwintering, use a well-draining potting mix and a pot large enough to accommodate the root system.

Repot in early spring.
