- 1). Fill 3-inch-diameter seedling pots with a moistened soilless potting mixture. Leave a 1/2-inch space between the top of the mix and the rim of the pot.
- 2). Sow two hollyhock seeds per pot, planting them 1/4 inch deep in the soil mix. Mist the soil surface with water to moisten.
- 3). Cover the pots with a plastic bag to help retain moisture during germination. Place the pots in a 60 to 65 F location to germinate.
- 4). Remove the plastic once sprouts appear. Move the pots to a warm, sunny windowsill and water when the soil surface begins to feel dry.
- 5). Thin each pot to one plant once the hollyhocks produce their second set of leaves. Pluck the weaker of the two seedlings from the pot, leaving the strongest seedling to continue growing.
- 6). Transplant the hollyhocks to a full sun, well-drained garden bed once all frost danger is past in spring. Plant the flowers at the same depth in the bed as they were in the pot, spacing them approximately 12 inches apart in all directions.
