Hollyhocks are charming perennial flowers that add height and color to any garden. Propagating hollyhocks from seed is an economical and rewarding way to expand your garden. With proper techniques, you can enjoy these beautiful blooms year after year.
Choosing the Right Seeds
Select high-quality seeds from reputable suppliers. Look for varieties that suit your climate and garden conditions. Fresh seeds have a higher germination rate, so always check the packaging date.
When to Sow Hollyhock Seeds
The best time to sow hollyhock seeds is in early spring, after the danger of frost has passed. Alternatively, you can start seeds indoors 6-8 weeks before the last expected frost date to get a head start.
Preparing for Sowing
Choose a well-draining seed-starting mix and fill seed trays or pots. Moisten the soil with water, but avoid waterlogging. Hollyhocks prefer full sun, so select a bright location for seedlings once they sprout.
Sowing the Seeds
Scatter seeds on the surface of the moist soil. Hollyhock seeds require light to germinate, so do not cover them with soil. Gently press the seeds into the soil surface to ensure good contact.
Germination and Care
Keep the soil consistently moist but not soggy. Maintain a temperature of around 70°F (21°C). Germination typically occurs within 10-14 days. Once seedlings appear, provide ample light and keep the soil moist.
Transplanting Seedlings
When seedlings develop their first true leaves and are sturdy enough to handle, transplant them outdoors. Space plants about 18-24 inches apart to allow for growth. Choose a sunny site with well-draining soil.
Growing Hollyhocks from Seed
Hollyhocks prefer full sun and tolerate a range of soil types. Water regularly, especially during dry spells. Mulching helps retain moisture and suppress weeds. Tall plants may need staking to prevent wind damage.
Dealing with Pests and Diseases
Hollyhocks are susceptible to rust, a fungal disease that causes orange spots on leaves. Remove affected foliage and improve air circulation. Watch for pests like aphids and Japanese beetles, and control them with appropriate methods.
Enjoying Your Hollyhocks
With patience and proper care, your hollyhocks will bloom in their second year. They attract pollinators such as bees and butterflies, adding life to your garden. Regular deadheading encourages more blooms and prolongs the flowering period.
