Planting & Care

Sow Woolly Rose Mallow seeds indoors 6-8 weeks before the last frost. Nick or lightly scarify the seeds and soak them in warm water for 24 hours to improve germination. Press seeds into a moist seed-starting mix, barely covering them, and keep at 70-75°F. Germination can be slow and uneven, often taking 3-6 weeks. Once seedlings have several true leaves and danger of frost has passed, transplant outdoors after hardening off. Space plants 24-36 inches apart in a sunny location with moist soil.

Keep the soil consistently moist, especially during the first growing season. Mulch around the base to retain moisture and suppress weeds. Woolly Rose Mallow is generally low-maintenance once established; cut back dead stems in late winter or early spring to encourage fresh growth.
