November in Zone 4 is the last working month before winter closes the garden. The ground is cooling fast, hard frosts are normal, and the remaining jobs are mulching, protecting pots and perennials, and checking stored produce. The average first frost (September 15 to October 1) is behind you now, so the garden's year is essentially done outdoors. This guide covers what to plant in november zone 4: final harvests, putting beds to bed, and winter preparation.
What November means in Zone 4
USDA Zone 4 has average winter lows of -30 to -20°F. The two dates that shape every decision are the frost averages: the average last spring frost falls around May 1 to 15 and the average first autumn frost around September 15 to October 1, giving a growing season of roughly 120 to 140 days. Those figures come from USDA zone averages and NOAA frost records — they are averages, not promises for any single garden, and they vary with microclimate, elevation and the year itself. Always check your local extension service before planting tender crops outside. The planting calendar hub gathers every month, and hardiness zone finder turns the averages into dates for your garden.
November garden task list
- Mulch garlic, perennials and strawberry beds thickly.
- Put the garden to bed: clear dead growth, compost healthy material, bin diseased material.
- Clean, oil and store tools; drain and store hoses.
- Protect pots and tender shrubs with fleece or move them under cover.
- Check stored produce weekly and use anything soft first.
- Order seeds and plan next year's beds while the season is fresh in mind.
What to start indoors in November
Indoor sowing is limited to windowsill crops: microgreens, herbs and a few pots of lettuce. Onions and leeks are not started yet — that job belongs to deep winter. Use this month to plan: sort seed packets, check what is left, and make the seed order list for the new year. A small indoor herb garden — parsley, chives, mint in a pot — keeps fresh flavour in the kitchen all winter. Use frost date calculator to work back from your last frost average, and give seedlings strong light and moist, well-drained soil.
What to direct-sow in November
Nothing is direct-sown outdoors now except garlic if the ground is still workable in the first days of the month — after that, the ground is too cold. Cover crops sown earlier should be establishing; if a bed is still bare, mulch it thickly instead of sowing. Bulbs for spring flowers can still go in while the soil can be dug. Everything else waits for spring. Sow into soil that crumbles in the hand, water gently, and mark every row.
What to harvest in November
Harvests are down to the hardiest: leeks, kale, Brussels sprouts and parsnips, which all tolerate cold and taste better after frost. Lift any remaining carrots and beets before the ground freezes solid. Stored produce — onions, garlic, potatoes, squash — should be checked weekly. Indoor microgreens and herbs are the freshest pickings now. Pick in the morning when leaves are crisp, and pick little and often so plants keep producing.
Frost protection in November
Hard frosts are now normal and the ground may freeze. The frost-protection job is about survival, not extension: mulch keeps the soil temperature steadier, fleece protects shrubs, and pots need insulation or shelter. Do not uncover plants on a mild day and forget to cover them again — the next frost is usually only a night away. Frost dates here are averages; your garden's microclimate may be colder or milder. Keep fleece, cloches and row cover within reach all month — a cover put on before dusk is the cheapest frost protection there is.
November planting data
The table below uses broad published ranges — they vary by variety, climate and soil.
| Crop | How to sow | Days to maturity | Germination (days) | Cold tolerance | Spacing |
|---|---|---|---|---|---|
| Garlic | Direct sow (cloves) | 180–240 | 7–14 | Hardy | 6 in |
| Spinach | Direct sow | 40–50 | 7–14 | Hardy | 4–6 in |
| Radishes | Direct sow | 25–40 | 4–7 | Hardy | 2–3 in |
| Kale | Direct sow / transplant | 50–65 | 7–10 | Hardy | 12–18 in |
| Turnips | Direct sow | 40–60 | 7–10 | Hardy | 4–6 in |
| Carrots | Direct sow | 60–80 | 14–21 | Hardy | 2–3 in |
What not to do in November
Do not leave the garden untidy: diseased foliage left over winter harbours pests and disease for spring. Do not forget to drain outdoor taps and hoses before a hard freeze. Do not plant anything tender outside, no matter how mild a day feels — winter has arrived. And do not skip mulching garlic; unmulched cloves heave out of the soil in freeze-thaw cycles.

Frequently asked questions
Can I plant anything outside in November in Zone 4?
Hardy crops such as peas, spinach, lettuce, radishes and carrots can go out in November when the soil can be worked, while tender crops such as tomatoes, beans, squash and basil must wait until after the average last frost, May 1 to 15. Check your local extension service before planting.
When is the last frost in Zone 4?
The average last spring frost in Zone 4 falls around May 1 to 15, and the average first autumn frost around September 15 to October 1. These are USDA/NOAA zone averages, not exact dates — microclimate and the year itself shift them, so check your local extension service.
What seeds should I start indoors in November in Zone 4?
Slow growers such as onions, leeks, celery, peppers and eggplant are started earliest, while tomatoes follow once you have strong light. Work back from your last frost average.
Should I plant garlic in November in Zone 4?
Garlic is an autumn planting in Zone 4: it needs 180 to 240 days and a cold period to form bulbs, so cloves go in before the ground freezes, spaced about 6 inches apart, and mulched thickly. If the ground is already frozen solid in November, the window has passed — plant garlic earlier next year rather than forcing cloves into frozen soil.
