Plan & order

  • Soil testaround Feb 6

    A $20 test now tells you what to amend before planting instead of guessing all season.

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.
