Sow indoors in pots in January or early February. Keep at 35-40°F for 10 days, then at 65-70°F. Provide moist conditions by placing a humidity dome over the containers until germination occurs.
Direct sow in late spring to summer for flowers the following year. Sowing early indoors will produce flowering plants in summer and fall.
PLACEMENT & CULTIVATION
This cottage garden favorite blooms in a seemingly never ending display, for the large saucer-shaped flowers open in succession from the bottom up. Providing a strong vertical accent in gardens, they look great supported by a picket fence or against a shed. Stake if growing in windy areas and space well apart to increase air circulation and avoid disease. Not tolerant of saturated wet soils, especially in winter. Self-sows.
1" a week. Drought tolerant once established due to its tap-rooted nature.
Mix in 2" of compost before planting.
Diseases & Pests:
Avoid fungal rust problems by spacing plants properly and planting them in a location that receives good air flow. If hollyhock rust has ever been a problem spray with organic fungicide preventively throughout the season or plant in a new location. If slugs are troublesome to new seedlings sprinkle some diatomaceous earth or iron phosphate pellets on the ground around the plants.
When to Cut for Bouquets:
Harvest when 1/3 of flowers are open.
