How to Plant Blue Woodruff

  • Start Blue Woodruff seeds indoors in the late winter for transplanting out in the spring. Or, many gardeners recommend sowing the herbs seeds directly outdoors in prepared seedbeds several weeks before the end of frost season.
  • To plant direclty outdoors, prepare garden soil by removing all weeds and debris.
  • Add compost if needed to ensure that the soil will drain well.
  • Sow 4 - 5 seeds per plant every 9 - 12 inches in the late fall.
  • Cover 1/4 inch and firm soil lightly.
  • Keep the area moist for germination.
  • If starting in pots/cells indoors, use 4 - 5 seeds per pot/cell
  • Start either in late winter approximately 10 - 12 weeks before last frost date.
  • keep moist until germination.
  • Seed germinate best in cooler temperatures of 39F for 2 weeks then move to 50F.
  • You can transplant outside when the last frost has passed at the earliest and the seedlings have true leaves.
  • Before transplanting, seedlings need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

  • Blue Woodruff herb does not perform well in extremely hot weather, so it may not survive the hottest weeks of summer.
