What to Plant in October in Zone 5

In USDA zone 5, October is mainly garlic month. Established spinach, lettuce, kale, carrots, and radishes may continue under protection, but most new seedings are risky as daylight and soil temperatures fall.

Count backward from your local first frost. Check the zone 5 October calendar, first frost guide, and what to plant now.

Plant Now

Protect and Harvest

Keep row cover ready for established greens. Harvest tomatoes, peppers, basil, beans, and other tender crops before frost. Leave healthy roots in the ground only when mulch and soil drainage make winter holding practical.

Next Steps

Plant garlic, check covers, and stop sowing crops that cannot finish before your frost date. Compare October zone 4 and October zone 6.

Before the first 32F night, use the Frost Harvest Desk to see what to pick now and what can stay in. Guide: what to harvest before the first frost.

Flowers: pansy, snapdragon, and hardy flowers such as purple coneflower, black-eyed Susan, and columbine have catalog windows to about October 10. Wait until about November 1 to sow breadseed poppy. Sweet peas are a spring sowing here. See flower seeds to sow in fall by zone and when to sow poppy seeds by zone.

Herbs: before nights linger near 50F, pot basil and other tender herbs for a windowsill winter garden. In cold zones, bring rosemary indoors. Hardiness table: which herbs survive winter by zone. Care: rosemary indoors and basil and tender herbs indoors.

Spring bulbs: plant tulips, daffodils, and crocus Sep 26 to Oct 24 in zone 5, or as late as about Nov 21 while the ground is open. See the Bulb Desk and when to plant tulip bulbs by zone.

Frost and Freeze Protection

Check kill temperatures on the Frost Harvest Desk. See which vegetables survive a hard freeze, how to use row cover and low tunnels, and what temperature kills tomato and pepper plants.
