Growing hollyhocks (Alcea rosea) in the garden is the goal of many gardeners who remember these impressive flowers from their youth. The flower stalks on hollyhocks can reach heights of 9 feet tall! They can tower above a garden, adding a lovely vertical element to your yard. Let’s look at a few tips on hollyhocks to help you grow them in your yard. How to Plant Hollyhocks The first thing to understand is how to plant hollyhocks. Hollyhocks need full sun and moist, rich, well drained soil. The mistake many novice hollyhock growers make is to plant this flower in soil that is too dry. If you are planting seeds, sow the seeds outside about a week before last frost. If you are planting seedlings out, wait about two to three weeks after last frost. Hollyhock seeds only need to be planted right below the soil, no more than 1/4-inch deep. Hollyhock plants should be about 2 feet apart to grow well. You can also plant bare root hollyhocks.
