Homegrown herbs are wonderful to have on hand for culinary purposes, natural beauty recipes, and for their natural healing properties. Just because the cold season is beginning does not mean that you have to say goodbye to your herb garden.

Many herbs can overwinter outdoors if cared for properly. You can also preserve herbs in creative ways and overwinter them indoors. Learn how to overwinter herbs with these simple tips.

How to Prep Outdoor Herbs to Survive the Winter

Follow these steps to ensure that your herb garden is ready to face the elements.


Start by removing any weeds growing up around the base of your herbs, so that they are not choked when they begin to grow again in the spring.


Oregano, rosemary, lemon verbena, thyme, and sage can all overwinter outdoors and will benefit from a good prune in the fall. Trim away the uppermost leaves and any dead flower heads, and prune back all dead wood on the plant.

You’ll probably find that you’ve pruned away lots of usable herbs—see different ways of preserving them for use over the winter.

All herbs will benefit from a two-to-four-inch layer of mulch to prevent the ground from freezing and to shield them from the harsh winter cold. Some herbs will need extra coverage in the form of a burlap wrap, cardboard box, or horticultural fleece over them to keep them insulated.

Herbs in Winter that Need to be Moved Inside

Annual herbs such as basil, pineapple sage, dill, borage, parsley, nasturtium, stevia, chamomile, and lemongrass are sensitive to cold temperatures. These herbs will likely not survive the harsh outdoor conditions.

Instead of digging these up completely, try propagating them from cuttings and growing them indoors. Growing basil from cuttings is particularly easy to do.

Both annual and perennial herbs can be planted in containers and brought inside before the first hard frost of the season. There are a ton of creative ways to grow herbs indoors. Not only will these plants look pretty on your kitchen windowsill or counter, but it’s a practical solution too. It is great to be able to harvest fresh herbs right from your kitchen as you are cooking!

Parsley can be difficult to dig up, as it has long roots that are easily disturbed. Dig deep beneath the plant and pot it in a container with a lot of depth, about ten inches.

Mint, thyme, and oregano are easy to dig out of the ground and take well to growing indoors.

Rosemary can thrive indoors, but it can also be difficult. Your best bet is to place it in a window where it will be cool and get a lot of natural light. For more on this herb, keep an eye out for our upcoming Guide to Rosemary which will be posted soon.

Before bringing any herbs indoors, be sure to check them carefully for pests and pest damage. If you see any, spray the plants with a bit of soap mixed with water to get rid of unwelcome creepy crawlies.

Amend the Soil

If you dig up your herbs and bring them indoors for the winter, it is the perfect time to add nutrients to the soil for next spring when you replant your herbs. Dig compost material into the soil and in the spring your bed will be richer and more nutritious, producing healthier, more prolific plants.

The good news is that amending your soil is an inexpensive and eco-friendly thing to do. For my book Garden Alchemy, I spent quite a bit of time experimenting and studying with natural soil amendments and found the results fascinating. I think you will too – see my post here about how to amend soil naturally.

More Ways to Protect Your Garden in the Winter

Herbs in winter aren’t the only plants that need your attention and care! Here’s how you can get a late harvest and protect the rest of your garden in the harsh winter months. It’s well worth the time and care in the colder months to see a thriving garden continue to live on year-round!

More Posts About Herbs:



  1. You talk about propagation of annuals like lemongrass, but did not get into propagating lemongrass. As it does not have hard and soft wood, how would i do this? Also, the lemon verbena…would i follow propagation instructions of hard/soft wood hebs?

  2. If I plant these outside and they grow and say winter comes along and they die. Will they grow back from the original seeds? Or do I have to replant them?
