How to Germinate and Grow Hollyhock
Germination Instructions
Preparation:

Choose a seed tray or small pots with good drainage. Fill them with a seed-starting mix, which is light and well-draining.
Sowing Seeds:

Soak the hollyhock seeds in warm water for 12 hours before sowing to soften the seed coat and improve germination.
Sow the hollyhock seeds on the surface of the soil and lightly press them into the soil. Cover them with a thin layer (about 1/4 inch) of seed-starting mix or vermiculite.
Watering:

Water gently to moisten the soil without washing the seeds away. Use a spray bottle for even distribution. Keep the soil consistently moist but not waterlogged.
Light and Temperature:

Place the seed trays in a location with bright, indirect light. The ideal temperature for germination is between 60-70°F (15-21°C).
Germination Time:

Hollyhock seeds typically germinate in 10-14 days. Maintain consistent moisture and light conditions.
Growing Instructions
Transplanting:

Once the seedlings have at least two sets of true leaves and are strong enough to handle, transplant them to their final location. Harden off the seedlings by gradually exposing them to outdoor conditions over a week.
Site Selection:

Choose a location with full sun. Hollyhocks prefer well-draining soil enriched with organic matter. Prepare the planting area by loosening the soil and adding compost if necessary.
Planting:

Plant the seedlings 18-24 inches apart to allow adequate air circulation and growth. Dig a hole large enough for the root ball and plant at the same depth as they were in the seed tray.
Watering:

Water regularly to keep the soil consistently moist, especially during dry periods. However, avoid overwatering, as hollyhocks do not like soggy soil.
Feeding:

Fertilize the hollyhocks with a balanced, water-soluble fertilizer once every 4-6 weeks during the growing season. Avoid over-fertilizing as it can lead to excessive foliage growth with fewer blooms.
Mulching:

Apply a layer of mulch around the base of the plants to retain moisture, regulate soil temperature, and suppress weeds.
Care and Maintenance:

Hollyhocks can grow quite tall and may need staking to support the stems, especially in windy areas. Deadhead spent flowers to encourage continuous blooming and prevent self-seeding.
Pest and Disease Control:

Monitor for pests like aphids and treat as necessary with insecticidal soap or neem oil. Hollyhocks can be susceptible to rust, a fungal disease. To prevent rust, water the plants at the base to keep the foliage dry and provide good air circulation around the plants.
Overwintering:

Hollyhocks are biennials, meaning they usually grow foliage the first year and bloom the second year. In colder climates, apply a layer of mulch or straw to protect the plants during the winter months."
