Sow hollyhocks correctly

If you would like to prefer your hollyhocks in winter, start sowing around February. You can also sow indoors in March, but from April it is more advisable to grow them outdoors. Hollyhocks grown outdoors are more robust and winter-proof than those grown in warm rooms.

The seeds of the hollyhock are large enough to be distributed individually in the nursery pot. This will make it easier for you to prick out the young plants later. Water the seeds well and keep them evenly moist during the germination period. The first green leaves can be seen after about 2 - 3 weeks. A few weeks later you can carefully prick out the plants.

Plant hollyhocks

If the days are already pleasantly mild in May, then put your hollyhocks grown indoors outside for hours during the day. So you can slowly get used to the sun and the fresh air. If night frost is no longer to be expected, then plant the hollyhocks in the chosen location that is as sunny as possible.

You should transplant hollyhocks sown outdoors in autumn, then they have enough time to grow and develop their deep taproots before winter. In the next year you can look forward to the colorful blooms from around June or July.

The essentials in brief:

  • Pulling forward in the warm possible but not required
  • Cover seeds with soil (dark germinator)
  • Keep sowing evenly moist
  • Germination time approx. 2 - 3 weeks
  • Prick out young plants
  • keep sufficient distance when planting out
  • Outdoor sowing brings more resilient plants


Hollyhocks brought forward in February can still bloom in the year of sowing. If you decided on these plants late, there is still a chance of early flowering.
