February looks much like January from the window — snow, frozen soil, short days — but under grow lights it is a busier month. The days are lengthening, seed catalogues are arriving, and the slow crops you started in January are up and growing. February is when you add the next wave of indoor sowings and when the year's plan stops being a sketch and becomes a sowing schedule worked back from your average last frost.
The discipline February demands is the same as January's: start only what benefits from a long indoor season.
Zone 2 in February: the frost window
Zone 2 is one of the coldest USDA zones, with winter lows of -50 to -40°F. The average last spring frost falls June 1–15 and the average first autumn frost falls August 15–September 1, which leaves roughly eleven to thirteen weeks between the average last spring frost and the average first autumn frost. Everything here runs on a very late timetable: tender crops go out only in June, and the whole outdoor season is a sprint. Those dates are USDA zone averages from the USDA Plant Hardiness Zone Map and NOAA frost records — they are ranges, not exact dates for any one garden, and they vary by microclimate, elevation and year, so check your local extension service before you plant tender crops outside. Our harvest date calculator gives you the averages for your zone, and the planting calendar hub lists every zone and month.
Your February task list
- Work out indoor sowing dates by counting back from your average last frost — our seed-starting calculator does the arithmetic for you.
- Order any seeds you have not yet bought, and check germination of old packets before you depend on them.
- Set up or check grow lights: seedlings need strong light close above them, not a dim corner.
- Pot on January seedlings and start peppers and eggplant.
- Plan succession sowing for the short summer, so fast crops such as lettuce and radishes follow each other instead of all maturing at once.
- Keep houseplants away from cold glass and radiators, and water sparingly while growth is slow.
What to start indoors in February
- Hot and bell peppers — Peppers germinate in 7–14 days and need warmth to do it — a heat mat or a warm spot helps. Sow them now and you will have sturdy plants by transplant time instead of small, late ones.
- Eggplant — Eggplant is another slow, heat-loving crop, taking 70–85 days to maturity. Start it with the peppers, in warm soil, under strong light.
- Onions and leeks (second sowing) — If your January sowing was thin or patchy, a February repeat is cheap insurance. Onions take 90–120 days, so there is still time.
- Parsley and other slow herbs — Parsley germinates in 14–28 days, so start it now. Keep the seed compost moist and be patient — it is one of the slowest herbs to appear.
Give seedlings strong light close above them, keep the soil moist but not soggy, and label every tray with the crop and sowing date.
What to direct-sow outdoors in February
Outdoor sowing is still not possible while the ground is frozen. February sowing is indoor sowing, plus microgreens and sprouts on the windowsill for fresh eating. If you have a heated greenhouse or a very bright, warm sunroom, you can also start hardy flowers such as sweet peas and snapdragons indoors now for transplanting later.
What to transplant and harvest in February
Nothing goes outside in February. The job is potting on: move January seedlings into slightly larger pots when they have a couple of true leaves, and keep them under lights a few inches above the leaves. A small fan on low nearby builds sturdier stems and discourages damping off, the fungal disease that kills seedlings at soil level.
There is still no outdoor harvest. February eating from the garden means stored onions and garlic, frozen or preserved produce from last year, and indoor microgreens — radish, pea shoots and sunflower shoots are ready in one to two weeks. Check stored crops again and compost anything soft before it spoils its neighbours.
Frost protection in February
February frost needs no active defence outdoors, because nothing tender is outside. The protection that matters is for seedlings indoors: a cold windowsill at night can chill peppers and eggplant enough to stall them, so move trays away from the glass overnight or insulate them. Watch for late-winter thaws that tempt you to sow outside — the ground will freeze again, and seed sown into frozen soil will rot rather than germinate.
February planting data — Zone 2

| Onions | 7–14 days | 90–120 days | 4–6 in | 6.0–7.0 | hardy |
| Celery | 14–21 days | 100–130 days | 8–12 in | 6.0–7.0 | frost-tolerant |
| Lettuce | 7–10 days | 45–60 days | 8–12 in | 6.0–7.0 | hardy |
| Radishes | 4–7 days | 25–40 days | 2–3 in | 6.0–7.0 | hardy |
Frequently asked questions
Can I plant anything outside in February?
No — the ground is still frozen and no vegetable will survive outdoors in February in a zone this cold. February is an indoor month: peppers, eggplant and a second sowing of onions and leeks.
Is February too early to start tomatoes?
For most gardeners in a cold zone, yes. Tomatoes grow quickly once warm, so starting them in February usually produces leggy plants that wait too long indoors.
Why do my seedlings get leggy?
Almost always too little light. Seedlings stretch toward a dim window and grow tall, pale and weak.
When is the last frost in my zone?
In Zone 2, the average last spring frost falls June 1–15 and the average first autumn frost falls August 15–September 1. Frost dates here are zone averages, not exact dates for any one place, and they vary by microclimate, elevation and year — check your local extension service before planting tender crops outside.
February is the month the garden moves indoors in earnest. Peppers and eggplant under lights, onions potted on, and a sowing calendar pinned to the wall — that is February done right. Browse the planting calendar hub for every month in your zone, see last month, or look ahead to next month, and see how the same month looks in a milder zone in the Zone 7 January guide.
