Will Herbs Survive Winter in Pots? Complete Guide to Growing Herbs

By Alex Assoune Jul 07, 2025

Growing herbs in pots is a practical way to enjoy fresh, fragrant plants year-round—whether you're cooking in the kitchen or decorating your balcony. But when winter rolls around, many gardeners worry: Will my herbs survive the cold?

The short answer is: some will, some won’t—and it depends on the type of herb, the climate you live in, and how you care for your potted plants during the colder months.

In this guide, we’ll explore which herbs are hardy enough to handle winter in pots, how to protect tender varieties, and practical tips to keep your potted herb garden thriving until spring.

Understanding the Basics: Herb Types and Hardiness

Herbs fall into three main categories: perennials, annuals, and biennials. Their survival in winter depends largely on which group they belong to.

1. Perennial Herbs

Perennials can live for many years and may survive winter if cared for properly. Some are naturally cold-hardy.

Cold-hardy perennial herbs that often survive winter in pots:

Thyme
Sage
Chives
Oregano
Mint
Lavender (depending on the variety)

These herbs can survive freezing temperatures, especially if they’re native to regions with cold winters.

However, even cold-hardy herbs may struggle in pots because container soil freezes faster than ground soil. Without insulation, roots in pots are more vulnerable to frost damage.

2. Tender Perennials

These herbs are perennials in warm climates but won’t survive harsh winters outdoors.

Examples include:

Rosemary
Lemongrass
Bay Laurel

In USDA Zones 7 and below, these herbs must be brought indoors or heavily protected.

3. Annual and Biennial Herbs

Annual herbs live only one growing season, regardless of winter protection. Biennials like parsley may survive one winter and bloom the following spring.

Common annual herbs that will not survive winter outdoors:

Basil
Cilantro
Dill

Once frost hits, these herbs usually die back. If you want to keep using them, grow them indoors or replant in spring.

Factors That Affect Winter Survival in Pots

Whether herbs survive winter in pots depends on several key factors:

1. USDA Hardiness Zone

Your hardiness zone determines how cold your area gets. The lower the zone number, the colder the winter.

Even hardy herbs that survive outdoors in Zone 6+ might not tolerate winters in Zones 3–5 without extra protection.

2. Container Material

Terracotta and ceramic pots are beautiful but porous and prone to cracking in freezing weather. They also conduct cold quickly.

Better winter pot choices include:

Thick plastic pots
Fiberglass containers
Wood planters
Insulated containers

3. Drainage

Good drainage is crucial. Cold + wet soil = root rot. Elevate pots off the ground and avoid saucers that hold water.

4. Exposure to Wind and Moisture

Cold winds dry out herbs quickly. Snow and rain can oversaturate the soil.

Shelter and mulch can reduce wind exposure and regulate moisture.

How to Protect Potted Herbs in Winter

If you want your potted herbs to survive winter, take action before the first frost. Here are effective strategies:

1. Bring Herbs Indoors

For tender herbs like basil, rosemary, or lemongrass, your best bet is to move pots indoors before temperatures drop below 40°F (4°C).

Tips for indoor overwintering:

Place near a sunny south-facing window.
Use grow lights if natural light is insufficient.
Water sparingly—herbs need less water in winter.
Watch for pests like aphids or spider mites.

2. Use Cold Frames or Mini Greenhouses

A cold frame is like a mini greenhouse that traps heat and blocks wind. Place your potted herbs inside for a sheltered environment.

This works especially well for herbs like thyme, chives, or parsley.

3. Insulate Outdoor Pots

If you want to keep herbs outdoors, insulate the containers.

Ways to insulate pots:

Wrap pots with bubble wrap, burlap, or old blankets.
Place pots close to walls or under eaves for added warmth.
Group pots together for shared protection.
Mulch heavily around the base with straw, bark, or leaves.

You can also bury pots in the ground to mimic in-ground conditions and protect roots from freezing.

4. Trim and Mulch

Cut herbs back slightly to reduce stress and conserve energy. Then add a thick layer of mulch over the soil to protect roots.

For example, chives and mint benefit from a trim and a 2–4 inch mulch layer before freezing temperatures arrive.

Herb-by-Herb Survival Guide

Let’s break down how specific herbs typically handle winter in pots:

Herb	Winter Survival in Pots	Overwintering Tip
Basil	No – dies in frost	Grow indoors under lights
Chives	Yes – cold hardy	Mulch well, may die back and regrow in spring
Rosemary	No in cold zones, yes in Zone 8+	Bring indoors, give full sun
Thyme	Yes – hardy	Trim, mulch, or use a cold frame
Mint	Yes – but invasive if not contained	Cut back, mulch, can go dormant
Oregano	Yes – hardy	Protect roots with mulch
Parsley	Yes – biennial	Mulch well, may produce again in spring
Sage	Yes – hardy in mild winters	Needs well-draining soil, protect roots
Cilantro	No – annual	Replant indoors or start again in spring
Lemongrass	No – tropical	Bring indoors or propagate from cuttings
Bay Laurel	No – only hardy in Zone 8+	Grow in a container and move indoors in winter

What to Do in Spring

Once the danger of frost has passed:

Gradually reintroduce indoor herbs to sunlight over several days to avoid sunshock.
Trim dead growth from perennials that survived winter outdoors.
Refresh the potting soil if needed.
Fertilize lightly to encourage new growth.

Even if some herbs die back completely, don't give up. Many will regrow from the roots once warmer weather returns.

Bonus Tips for Winter Herb Gardening

Start a windowsill herb garden with easy-to-grow herbs like basil, chives, or parsley.
Harvest conservatively in winter. Allow the plant to rest and conserve energy.
Avoid overwatering. Herbs in dormancy or low light need much less water.
Label your dormant pots so you remember what’s inside come spring.

Final Thoughts: Will Herbs Survive Winter in Pots?

Yes—with the right care and preparation, many herbs can survive winter in pots. Cold-hardy varieties like thyme, sage, and chives have a good chance outdoors, especially if insulated or sheltered. Tender herbs like basil and rosemary must be brought inside to survive.

Understanding your climate, choosing the right containers, and adjusting your care routine are key to overwintering success.

By taking a little time in the fall to prepare your herb garden, you’ll ensure that your favorite culinary and medicinal plants are ready to flourish again in the spring.
