Dormant care

  • Clean, sharpen and oil blades while there's time — dull tools bruise plants and slow you down.

  • Prune apples, pears and peaches while fully dormant — open the center, remove crossing wood.

Start indoors

  • A tray on the windowsill gives you a cut of fresh greens every 10-14 days through the cold months.

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

  • Onionaround Feb 24

    10 weeks of indoor growth before your last frost (05-05). Match day-length to your latitude — long-day north of 37°, short-day south.
