February · USDA Zone 6
winterWhat to plant in February in USDA zone 6
Winter planting guide for zone 6 (Southern Pennsylvania, Ohio, Missouri, parts of mid-Atlantic) — a 180-day growing season with last frost around mid- to late April and first frost around mid- to late October.
Sow indoors in February — zone 6
Start these seeds under lights or in a heated propagator so transplants are ready when the outdoor planting window opens.
- Peppers, eggplant, tomatoes (late February)
- Brassicas, lettuce, herbs (parsley, chives)
Sow outdoors in February — zone 6
Direct-sow these seeds into prepared garden beds or large containers. Soil temperature matters more than the calendar date — wait for a sustained warm-up before sowing tender crops.
Prep and planning — zone 6
- Cold frames and raised beds — Black plastic warms soil 2-3 weeks faster.
Universal February tasks
These apply across most US and UK gardens in February, regardless of zone.
- Start onions, leeks, and slow-growing perennials under lights.
- Prune fruit trees, grapes, and dormant shrubs while still leafless.
- Test soil where you can dig — collect samples for pH and nutrient reports.
- Top up cold-frame and cloche supplies; cover early beds for soil-warming.
- Stratify seeds that need cold (echinacea, milkweed, native perennials) outdoors or in the fridge.
- Inspect stored bulbs, potatoes, and dahlia tubers for rot.
Why this works for zone 6
Zone 6 has average annual minimum temperatures of -10 to 0°F (-23 to -18°C) and a frost-free window from mid- to late April to mid- to late October — about 180 growing days. Two-season growing — cool-season crops in spring/fall, warm-season in summer. Heirloom tomato varieties work well here.
Dates are zone-wide averages. Local microclimates (south-facing slopes, urban heat, lakeside warmth, elevation) can shift the window by 1-2 weeks within the same zone.
UK gardeners — February
In the UK, February brings broad beans, onion sets, shallots, and Jerusalem artichokes outdoors in milder regions. Sow tomatoes, peppers, and aubergines under heat indoors. Chit early potatoes in a cool, bright spot.
