How Should I Plant Hollyhock Seeds?


Hollyhocks are a tall, majestic flower that can grow to a height of 10 feet tall. Their tall, slender stalks are adorned with showy leaves and flower blossoms from summer into fall, which makes them a gardener's choice for a flower bed backdrop or a border plant along fences and walls. Hollyhocks are a no fuss plant and will provide you with more blooms year after year. Getting them started is a basic process, and can be done indoors, in late winter, or directly in the ground in spring.

Starting Seed Indoors

Step 1

Start hollyhock seeds indoors for a head start on the growing season. While many hollyhocks do not bloom until their second year, there is a good chance you will get a few blooms the first year if you start them early. Plan to start your seeds 8 weeks before all danger of frost has passed for your area.

Step 2

Fill 2-inch seed pots with a commercial seed starter soil mix.

Step 3

Set the hollyhock seed on top of the soil, and then cover with 1/4 inch of additional soil.

Step 4

Water until the soil is moist, and cover the trays with a pane of glass or a sheet of clear plastic wrap. Set the tray in a warm area of the house with bright light. Leave the cover in place until seeds germinate.

Step 5

Transplant the seedlings to an outdoor location after all danger of frost has passed. Select a location that has full sun and well drained soil.

Direct Sow Into Ground

Step 1

Select a location for your hollyhocks that receives full sun and has good soil drainage.

Step 2

Loosen the soil to a depth of 3 inches and add a 1-inch layer of compost to the site. Turn over the soil and work the compost in with the dirt. Rake the soil out smoothly when finished.

Step 3

Lay your hollyhock seeds on the ground, 6 inches apart, and cover with 1/4-inch of soil.

Step 4

Water seeds gently so the soil is moist. Keep seeds moist until germination occurs.

Step 5

Thin the hollyhock plants to between 18 and 36 inches apart once they are 3 to 4 inches tall.

Tips and Warnings

  • Hollyhock plants may need additional support if they are going to be planted in a windy location, as high winds can cause the stalks to break. Staking the plants or tying them to a fence post are both good options.
