How to grow

How To Grow Hollyhock From Seed: Establishing hollyhock from flower seeds is very rewarding. To get a jump start on the growing season, you can sow the seeds indoors or in the greenhouse 6 - 8 weeks before the last frost date. Use starter trays and quality starter mix and sow the seeds on the surface, pressing them into the soil to make good contact. Keep them consistently moist.

Sowing the flower seed directly outdoors is an option as well. Prepare soil bed, sow the seeds on the surface and dust over them very lightly with loose garden soil. Keep the seeds moist until germination has occurred. Young plants can be transplanted or even moved to other positions in the garden.

Flower Care

Hollyhock care includes weekly watering and use of a balanced fertilizer. Be sure to leave the last blooms on the plant even after the petals fall. They will drop their flower seeds and self-sow, and you'll be rewarded with plenty of new plants come spring. Cut back hard when flowering is done and seeds have dropped.
