How to Put the Garden to Bed by Zone
Fall closeout is the work between the last harvest and frozen ground. Order matters more than a perfect calendar date: clear disease first, plant what still fits your frost countdown, then mulch and store tools.
Do not invent a national frost date. Confirm timing with the first frost date tool or My Garden, then run the Garden to Bed checklist.
Suggested Order
1. Pull spent annuals and remove diseased foliage from the garden. 2. Finish tender harvest with Frost Harvest Desk. Leave frost-sweetened crops in. 3. Plant garlic, spring bulbs, or a cover crop only while that desk still shows an open window. 4. Mulch bare soil. Wait until the ground freezes before heavy crown blankets on tender perennials. See what to mulch before winter. 5. Drain hoses, clean tools, and bag a soil test if you have not tested in a few years. 6. Bring tender herbs indoors before nights linger near 50F for basil. Use which herbs survive winter by zone, how to bring rosemary indoors for winter, and when to bring basil and tender herbs indoors.
Zone Snapshot
These use ThriveThyme zone default first frost dates, not your yard. Count backward from your own frost date.
- Zones 3 to 5: First frost often arrives in September or early October. Clear tender crops early. Garlic and bulbs are often already in or nearly done. Winter rye may still fit empty beds after oats and legumes have closed.
- Zone 6: Typical first frost is mid to late October. October is prime closeout: harvest, garlic, bulbs, and a late rye cover if beds open up.
- Zones 7 to 8: Windows run into November. Keep planting cool-season food if beds are free, then garlic and bulbs. Mulch after soil cools.
- Zones 9 to 10: Hard freeze may be rare. Focus on spent-bed cleanup, cool-season planting, and soil care. Chill tulips and hyacinths before planting; see Bulb Desk.
Residue Rules
Extension guidance splits clean and diseased material. University of Minnesota Extension notes that residue can return nutrients when chopped and left or composted, but diseased residue is safer removed. Iowa State Extension urges thorough vegetable-garden cleanup because many pathogens overwinter on debris, while healthy perennial stems can stay for pollinators and frost-heave protection.
Next Steps
1. Open Garden to Bed and check off tasks for your zone. 2. Cross-check plant windows on Garlic Desk, Bulb Desk, and Cover Crop Desk. 3. Read which cover crop for spent beds if a bed is empty.
