Steps

  1. Pull out spent annual vegetables like tomatoes, peppers and cabbage. Cut tough stems with pruners and put diseased plant material in the trash, not the compost.

  2. Leave healthy roots and a few seed heads in place. Hollow stems and seed heads give beneficial insects a place to shelter over winter.

  3. Clear weeds and fallen leaves from the soil surface. Remove any debris that could hold pests or disease through the cold months.

  4. Spread a 2 to 3 inch layer of finished compost over each bed. You do not need to dig it in. Worms and frost will work it into the soil.

  5. Sow a cover crop such as winter rye or clover if you want extra protection. Scatter the seed evenly and rake it lightly into the top inch of soil.

  6. Water the beds after adding compost or sowing seed. Damp soil holds warmth better and helps cover crops germinate before the cold sets in.

  7. Mulch bare beds with straw or shredded leaves once freezing temperatures are close. A 3 to 4 inch layer keeps soil temperature steadier.

  8. Check and store your tools, hoses and supports. Drain hoses, clean pruners and bring fragile items indoors before the first hard freeze.

Tips and common mistakes

Do not leave thick layers of uncomposted kitchen scraps on the beds, as they attract rodents over winter.

Skip tilling in fall. Leaving soil structure intact protects the worms and microbes you want next spring.

Wait until the soil is cold before mulching heavily, so you do not trap warmth that keeps pests active.

Questions

Do I need to cover my raised beds in winter?

Not always. A layer of compost plus straw or leaves is enough in most climates. Cover crops add extra protection and free green manure.

Can I plant anything in my raised beds in fall?

Yes. Garlic and some cold-hardy greens can go in before the ground freezes. Otherwise, focus on feeding and protecting the soil.

What should I do with diseased plants?

Throw them in the trash rather than the compost bin. Home compost piles often do not get hot enough to kill disease.
