Dormant care

Start indoors

  • Alliums need 10-12 weeks under lights before they go out — the earliest sowing of the year.

  • Onionaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Match day-length to your latitude — long-day north of 37°, short-day south.

  • Pepperaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Pinch first flowers on transplants so the plant invests in roots before setting fruit.

  • Parsleyaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Soak seeds 24 hrs before sowing. Cut outer stems and it comes back for years in mild zones.

  • Chivesaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Divide the clump every 3 years — one plant becomes six with no effort.

  • Oreganoaround Feb 28

  • Thymearound Feb 28
