How to Grow Hollyhock Seeds


Hollyhocks grow glorious and tall in the back of the garden. Every other year these magnificent towers of color bloom and produce more seeds for the next growing season. There are single-bloom hollyhocks and double-bloom hollyhocks in almost any color you can imagine. Other than staking up the tall flower stalks, hollyhocks require very little care besides watering.

Spring Planting Procedures

Step 1

Choose a sunny location in the garden that receives at least six hours of direct sunlight. Hollyhocks love the sun and fresh air. An open fence line is perfect for planting hollyhock seeds.

Step 2

Scatter the hollyhock seeds directly on top of the soil in the flower bed. Top the seeds with a fine layer of top soil. The top layer of soil should be no more than 1/4 inch thick.

Step 3

Water the hollyhock seeds as soon as they are planted. Continue watering the seeds and do not allow them to dry out until the hollyhock seeds start to germinate.

Step 4

Keep the soil in the flower bed watered regularly, at least twice a week. Hollyhocks do not like dry roots. Weed the garden so the nutrients in the soil feed the hollyhocks and not the weeds.

Step 5

Allow the hollyhocks to grow and bloom, if applicable, for the first year. Many varieties of hollyhocks only bloom after a year of growing and a period of dormancy. The second year will have the hollyhocks producing lots of color for the garden.

Step 6

Cut the stalks of the hollyhocks back to the ground at the end of the growing season. Cover with a layer of mulch for over-wintering. Remove the mulch in the spring and allow the plants to grow as desired.

Fall Planting Procedures

Step 1

Sow the hollyhock seeds directly into the flower bed. The area must receive at least six hours of direct sunlight each day. Plant the seeds 1/4 inch deep.

Step 2

Water the seeds well and keep the soil moist until the hollyhock seeds germinate. Thin out unwanted plants or transplant to another garden area. Continue watering at least once a week.

Step 3

Cut back the hollyhock stalks to ground level after the first frost hits. The roots will continue to grow and establish into a good root system for spring.

Step 4

Mulch the new plants to protect them from the winter. Remove the mulch in the spring to allow the hollyhocks to sprout easily.

Step 5

Maintain a biweekly watering schedule for the hollyhocks in the spring. Either deadhead the flowers as they die or allow the hollyhock to drop the seeds and self-seed the area for new plants the following growing season.

Tips and Warnings

  • Hollyhocks are susceptible to leaf rust and must be treated with a fungicide to help control the problem. Another solution is to remove any infected leaves as soon as the fungus is discovered and disposing of the infected plant parts.
