If you live in a cold northern region, you might think your gardening options are limited. But the best herbs to grow in hardiness zone 3 2 are surprisingly tough and reliable. Many perennial herbs actually thrive in these frigid winters, coming back stronger each spring.
Zone 3 sees winter lows of -40°F, while Zone 2 can drop to -50°F. That’s seriously cold. Yet nature provides herbs that not only survive but flourish in these conditions. You just need to choose the right varieties and give them proper care.
This guide covers the top herbs for your short growing season. We’ll talk about planting, care, and harvesting so you can enjoy fresh herbs from your own garden.
Understanding Hardiness Zones 3 And 2
Hardiness zones tell you which plants can survive your local winter temperatures. Zone 3 includes areas like northern Montana, parts of Minnesota, and much of Canada. Zone 2 is even colder, found in northern Alaska and some Canadian territories.
Your growing season is short, typically 90-120 days for Zone 3 and even less for Zone 2. But many herbs are perennials that go dormant in winter and wake up in spring. Others are annuals that complete their life cycle in one season.
Key Factors For Success
- Choose perennial herbs rated for Zone 3 or colder
- Plant in spring after the last frost date
- Use mulch to protect roots during winter
- Consider raised beds for better drainage
- Provide full sun when possible
Best Herbs To Grow In Hardiness Zone 3 2
Now let’s get into the specific herbs that perform well in these cold zones. These are tried and true varieties that gardeners in northern climates rely on.
Chives
Chives are one of the easiest herbs for cold climates. They are hardy to Zone 3 and even Zone 2 with good snow cover. Chives form clumps of grass-like leaves with a mild onion flavor.
Plant chives from seed or divisions in early spring. They prefer full sun but tolerate partial shade. Chives need regular watering, especially during dry spells.
Harvest by snipping leaves near the base. The more you cut, the more they produce. Chives die back in winter but return reliably each spring. Their purple flowers are edible too.
Oregano
Oregano is a hardy perennial that survives Zone 3 winters with ease. Greek oregano is the most flavorful variety for cooking. It spreads slowly and forms a low mat of leaves.
Start oregano from seed indoors 6-8 weeks before the last frost. Transplant outside after danger of frost passes. Oregano needs well-drained soil and full sun. It’s drought tolerant once established.
Harvest leaves just before flowers open for the best flavor. Dry or freeze oregano for winter use. Mulch around plants in late fall to protect roots from heaving.
Mint
Mint is incredibly cold hardy, surviving Zone 2 winters without trouble. Spearmint and peppermint are both excellent choices. Mint spreads aggressively, so plant it in containers or use barriers.
Plant mint in spring after frost. It prefers moist soil and partial shade. Mint grows fast and can take over a garden bed if not controlled.
Harvest mint leaves anytime during the growing season. Use fresh in teas, salads, or desserts. Mint dies back in winter but returns from underground runners in spring.
Thyme
Thyme is a low-growing perennial that handles cold winters well. Common thyme and lemon thyme are both hardy to Zone 3. Thyme forms a dense mat of tiny leaves with a strong aroma.
Start thyme from seed indoors or buy transplants. Plant in full sun with well-drained soil. Thyme doesn’t like wet feet, so avoid heavy clay soils.
Harvest sprigs as needed once plants are established. Thyme dries well and retains its flavor. In winter, thyme stays green under snow cover in milder areas.
Sage
Garden sage is a woody perennial that survives Zone 3 winters with protection. Common sage and purple sage are both good options. Sage has soft, gray-green leaves with a earthy flavor.
Plant sage in spring after frost. It needs full sun and well-drained soil. Sage is drought tolerant once established. Prune lightly after flowering to keep plants compact.
Harvest leaves before flowers open for the best taste. Sage is excellent with poultry and pork. Mulch heavily in late fall to protect the crown from freezing.
Lavender
Lavender is trickier in cold zones but possible with the right variety. English lavender (Lavandula angustifolia) is the hardiest, surviving Zone 3 with good drainage and snow cover. Munstead and Hidcote are reliable cultivars.
Start lavender from seed indoors 10-12 weeks before the last frost. Transplant after frost, spacing 18-24 inches apart. Lavender needs full sun and alkaline, sandy soil. Good drainage is critical for winter survival.
Harvest flower stems when the lower flowers open. Dry lavender for sachets, teas, or baking. In winter, cover plants with evergreen boughs or straw for extra protection.
Tarragon
French tarragon is a perennial herb hardy to Zone 3. It has a distinct anise-like flavor used in chicken and fish dishes. Tarragon doesn’t produce viable seeds, so buy plants or divisions.
Plant tarragon in spring after frost. It prefers full sun and well-drained soil. Tarragon grows 2-3 feet tall and needs staking in windy areas.
Harvest leaves throughout summer. Tarragon loses flavor when dried, so freeze it instead. Divide plants every 3-4 years to maintain vigor.
Parsley
Parsley is a biennial but grown as an annual in cold zones. It’s hardy to Zone 3 but usually doesn’t survive winter. Curly and flat-leaf parsley are both easy to grow.
Start parsley from seed indoors 8-10 weeks before the last frost. Soak seeds overnight to speed germination. Transplant outside after frost. Parsley needs rich, moist soil and partial shade in hot areas.
Harvest outer leaves as needed. Parsley is packed with vitamins and adds freshness to dishes. In mild winters, parsley may survive under mulch.
Dill
Dill is an annual herb that grows quickly in cool weather. It self-seeds readily, so you may get volunteers next year. Dill has feathery leaves and seeds used in pickling.
Sow dill seeds directly in the garden after the last frost. Plant every 2-3 weeks for a continuous harvest. Dill needs full sun and well-drained soil. It doesn’t transplant well.
Harvest leaves before flowers open. Collect seeds when they turn brown. Dill attracts beneficial insects like swallowtail butterflies.
Cilantro
Cilantro is a cool-season annual that bolts quickly in heat. It’s perfect for short growing seasons. Cilantro leaves are used in Mexican and Asian cooking, while the seeds are coriander.
Sow cilantro seeds directly in the garden every 2 weeks for a steady supply. Plant in partial shade to delay bolting. Cilantro needs regular moisture.
Harvest leaves when plants are 6 inches tall. Let some plants go to seed for coriander. Cilantro self-seeds easily in the garden.
Planting Tips For Cold Climate Herbs
Success with herbs in Zones 3 and 2 starts with proper planting. Here’s a step-by-step guide to get you started.
Step 1: Prepare The Soil
Most herbs prefer well-drained soil with a pH between 6.0 and 7.0. Test your soil and amend as needed. Add compost or aged manure to improve fertility.
If your soil is heavy clay, consider raised beds. They warm up faster in spring and drain better. This is especially helpful in cold zones.
Step 2: Choose The Right Location
Herbs need at least 6 hours of sunlight daily. South-facing slopes or areas near buildings provide extra warmth. Avoid low spots where frost settles.
Consider microclimates in your yard. A sunny spot against a wall can be several degrees warmer than open ground.
Step 3: Plant At The Right Time
Wait until the soil warms to at least 50°F. In Zone 3, this is usually mid to late May. For Zone 2, early June is typical. Use a soil thermometer to be sure.
Hardy perennials like chives and mint can be planted earlier. Tender annuals like basil need warmer soil.
Step 4: Water Wisely
Water deeply but infrequently to encourage deep roots. Most herbs prefer slightly dry conditions. Overwatering leads to root rot, especially in cold soils.
Use drip irrigation or soaker hoses to keep foliage dry. This reduces disease problems.
Step 5: Mulch For Winter Protection
After the ground freezes in late fall, apply 4-6 inches of mulch. Straw, leaves, or evergreen boughs work well. This insulates the soil and prevents heaving.
Remove mulch gradually in spring as temperatures warm. Don’t uncover too early or frost may damage new growth.
Overwintering Herbs In Zones 3 And 2
Winter is the biggest challenge for cold climate gardeners. Here’s how to protect your herbs through the cold months.
Perennial Herbs
Most perennials go dormant in winter. They don’t need watering or care during this time. But they do need protection from extreme cold and drying winds.
Apply a thick layer of mulch after the ground freezes. This keeps soil temperatures stable. Snow is an excellent insulator, so let it accumulate over herb beds.
Avoid pruning in fall. Leave dead foliage in place to catch snow and protect the crown. Cut back in spring after new growth appears.
Annual Herbs
Annuals like basil and dill won’t survive winter. Harvest them before the first frost. You can dry or freeze them for winter use.
Some annuals self-seed if you leave a few plants to go to seed. Next spring, you’ll have volunteers popping up.
Bringing Herbs Indoors
Some herbs can be dug up and brought indoors for winter. Chives, mint, and oregano adapt well to containers. Pot them up in late summer and bring inside before frost.
Place pots in a sunny window or under grow lights. Water sparingly during winter. Herbs may go semi-dormant but will perk up in spring.
Harvesting And Preserving Herbs
Fresh herbs are wonderful, but you’ll have more than you can use fresh. Here’s how to preserve them for winter.
Drying Herbs
Drying is the simplest preservation method. Harvest herbs in the morning after dew dries. Tie stems in small bundles and hang upside down in a dark, airy place.
Alternatively, dry leaves on screens or in a dehydrator. Store dried herbs in airtight jars away from light. They keep for 1-2 years.
Freezing Herbs
Freezing preserves flavor better than drying for some herbs. Chop herbs and place in ice cube trays with water or oil. Pop out cubes and store in freezer bags.
You can also freeze whole leaves on a baking sheet, then transfer to bags. Frozen herbs are best used within 6 months.
Making Herb Vinegars And Oils
Infused vinegars and oils are easy to make. Fill a jar with fresh herbs and cover with vinegar or oil. Let steep for 2-4 weeks, then strain.
Herb vinegars are great for salad dressings. Herb oils are wonderful for cooking. Store in the refrigerator for longest shelf life.
Common Problems And Solutions
Even hardy herbs face challenges in cold zones. Here are common issues and how to fix them.
Winter Kill
Some herbs may not survive winter despite being rated hardy. This often happens due to poor drainage or lack of snow cover. Improve drainage and add mulch for better protection.
If a plant dies, try a different variety next year. Some cultivars are hardier than others.
Frost Heaving
Repeated freezing and thawing can push plants out of the ground. This exposes roots to cold air. Mulch helps prevent heaving by keeping soil temperatures stable.
Check plants in early spring and press any that have heaved back into the soil.
Slow Growth
Cold soils slow down herb growth in spring. Be patient and don’t overwater. Once soil warms, growth will accelerate.
Using black plastic or row covers can warm soil faster. Remove covers once plants are established.
Pests
Cold climates have fewer pest problems, but aphids and spider mites can appear. Use insecticidal soap or neem oil for control. Encourage beneficial insects like ladybugs.
Healthy plants are less susceptible to pests. Provide good air circulation and avoid overfertilizing.
