Tips to Grow Hollyhock

  1. Arrange good quality hollyhock seeds.
  2. The soil should be well draining, moist and rich soil. Fill a tray with compost and water it well to ensure that it is consistently moist
  3. Sow the large seeds individually, spacing about an inch apart on the compost surface. When the tray is full, cover lightly with compost.
  4. Spaced widely, the seeds can germinate and grow on for a few weeks before you prick them out. Place the tray in a warm and cosy spot to germinate
  5. Hollyhocks take 10-14 days to germinate and then another 3-4 weeks before they’re ready for pricking out. If roots are showing at the base of the tray, they’re ready to move on.
  6. Hollyhocks will be ready for planting out in the garden
  7. You might get the odd plant trying to flower sooner, but snip off the flower spike. This helps the roots to get established before the demands of flowering begin.
