Hollyhocks are classic cottage garden staples that bring height and charm to any sunny border. These impressive plants produce tall, sturdy spikes covered in large, showy blooms throughout the summer. They are often grown as biennials, meaning they spend their first year establishing foliage and bloom in their second.

Entretien

Plant these in a spot that gets plenty of sun and has well draining soil to keep them happy. Stake the tall flower spikes if you live in a windy area to prevent them from snapping. Keep an eye out for rust on the leaves, which is a common fungal issue that looks like orange spots.

Arrosage
Water consistently to keep the soil moist but not soggy, especially during dry spells.
Engrais
Apply a balanced liquid fertilizer once a month during the active growing season.

Deadhead spent flowers to encourage more blooms and cut the stalks back to the ground after they finish flowering.
