How To Plant and Grow Hollyhocks From Seeds
Annual Hollyhocks need to be up and actively growing by February or early March.
If they do not get an early start, they will behave like biennials or you may get flowers in fall.
Start growing the Hollyhock seeds indoors to get a jump on the growing season. These flowers typically have a blooming season from July to September in most parts of the country.
Plant the seeds about 8 to 10 weeks before the last frost. Hollyhocks usually do not bloom until their second year. Plant 2-3 seeds per container, gently pressing the seed into the medium. Thin to one plant per container when the first true leaves appear. Harden off and transplant outside after the danger of frost has passed.
Will do best in full sun with a well-drained soil mix. In the greenhouse, we use a soil mix consisting of 1 part peat moss to 2 parts loam and sand. Plants are well watered and allowed to dry before watering again.
Use good soil with nutrients to help the seeds grow.
- Be sure to use pots with some depth as hollyhocks will grow long roots.
- Do not plant Holyhock Seeds too deep, just 1/4" in depth.
- If in fact you want to sow the seeds directly into the garden,Sow after last frost, gently pressing the seed into the soil. Thin when true leaves appear.
To transplant seedlings into the garden when all danger of frost has passed, be sure that the roots are covered well with soil and that the plants are 1 1/2 to 2 feet apart. They will grow best in full sun to partial shade and need watered regulary.
Hollyhocks have been known to cross pollinate, so gardeners should only grow one variety at a time to save pure seeds
- Seeds are ready to harvest when the seed capsules are completely dry and brown. The capsules can be taken of the plant and the seeds are easily separated from the paper-like husk.
In the garden, they need plenty of room. Final spacing should be 18-24". Give them plenty of room to allow air circulation and minimize rust and other disease.
Established Hollyhock plants can be separated by division.
This is best done in the fall to allow the replants time to grow good roots in their new location before winter.
Hollyhock like rich well drained soil. Water as needed to keep the soil moist at all times. Adding a general-purpose fertilizer once a month will result in bigger, fuller blooms.
After the growing season is over, you can cut back the Hollyhock to ground level. To assure that the plant does not die back completely, cover the area with mulch, in case the winter is harsh.
Rust disease is a common problem. We recommend you apply fungicides regularly.
