Like all perennials that self-sow, the decorative hollyhock is easy to grow in your own garden. This plant flowers only in its second year, so you should plan the sowing well in advance.
Hollyhocks can be sown directly outdoors or grown in pots
Sow the hollyhock - pot or open ground
You can grow the hollyhock indoors or sow it directly outdoors. Hollyhocks grown in warm weather may already flower the year they are sown, but the plants are not as hardy as those grown outdoors. They tend to suffer from diseases and are also not as hardy.
As dark germs, the seeds of the hollyhock should always be covered with some soil or substrate for germination. Water the seeds well and keep them evenly moist during the two to three week germination period. Outdoors, you can easily sow hollyhocks from April to midsummer.
Transplant the hollyhock
If you have not sown the hollyhocks in their final location, then you will have to transplant them at some point. The ideal time depends on where and when you grew the plants.
Hollyhocks sown indoors in winter must be transplanted in late spring, because then they are too big for the seed pots.(16.68€) Slowly get the hollyhocks used to the sun and the cold. At the end of May they can be planted outside. Hollyhocks sown in open ground or those that have self-grown are usually transplanted in the fall.
The essentials in brief:
- easy to grow from seed
- Direct sowing outdoors optimal
- Possibility to bring it forward when warm
- dark germs
- Water seeds well
- Keep the seedbed or pot evenly moist
