- Sketch this year's beds and move each crop family to a new spot - the garden planner and the crop rotation guide make it quick.
- Test old seed: roll ten seeds in a damp paper towel for a week. If fewer than seven sprout, sow thicker or buy fresh.
- If the ground isn't frozen, spread compost now so it's worked in by spring, and send off a soil test - January is when labs are quiet.
