🛠️ Maintenance
Plan, order seeds, and prep
The ground is cold or frozen — the perfect time for the indoor work that makes spring easier.
📌 Order seeds before favorites sell out, sketch next year's layout and rotations, sharpen and oil tools, and start onions/leeks late in the dormant season.
General October tasks
These apply broadly regardless of zone — a useful checklist alongside the zone-specific tasks above.
- ✓Harvest root vegetables before hard freeze: carrots, parsnips, beets (or mulch in place)
- ✓Plant spring bulbs in all but the warmest zones
- ✓Plant garlic if not already done
- ✓Sow overwintering cover crops: winter rye, hairy vetch, crimson clover
- ✓Mulch perennial beds with 3–4 inches after ground cools but before hard freeze
- ✓Bring tender perennials indoors before first frost
- ✓Direct sow cool-season crops outdoors in Zones 7–9
- ✓Plant container shrubs and trees — root establishment continues until ground freezes
⚠ Watch-outs for October
- ⚠Harvest sweet potatoes before soil temperature drops below 50°F or they become damaged
- ⚠Don't compost diseased plant material — bag and discard it
- ⚠Protect late-planted garlic beds from heaving with light mulch
- ⚠In warm zones, watch for incoming frost on marginal dates — have covers ready
