Overwintering Hardy Herbs: Bringing Your Herb Garden Indoors

Fall is here, and while your garden might be winding down, that doesn’t mean you have to say goodbye to your favorite herbs! Hardy herbs like rosemary, thyme, and oregano can be brought indoors to keep your kitchen flavorful all winter long. With a bit of TLC, you can enjoy fresh herbs even when it’s snowing outside. Here’s how to successfully transition your herbs from garden to windowsill and keep them thriving all season!

Why Overwinter Your Herbs Indoors?

Overwintering your herbs indoors is a great way to protect them from the harsh winter weather. Plus, it gives you access to fresh herbs all winter, which means flavorful soups, stews, and roasts! By moving them inside, you’re giving these hardy herbs a second chance to shine, and you’ll save money by not having to buy them at the store.

Choosing the Right Herbs to Bring Indoors

Not all herbs are ideal candidates for indoor growing, but the following hardy herbs make the transition easily and do well indoors:

• Rosemary: A Mediterranean favorite with needle-like leaves and a woody aroma.
• Thyme: A versatile herb with tiny, flavorful leaves that add depth to any dish.
• Oregano: A staple in Italian cooking, with robust, slightly spicy leaves.

These herbs are perennials, which means they’ll come back year after year, making them perfect for bringing inside and keeping alive until spring!

How to Prepare Herbs for the Move Indoors

Before bringing your herbs inside, it’s important to prepare them for the transition. Here’s a step-by-step guide to make the process smooth:

1. Inspect for Pests: Check your herbs for any unwanted guests like aphids, spider mites, or whiteflies. Spray the leaves with a gentle water jet or an insecticidal soap to keep pests at bay.
2. Trim and Prune: Give your herbs a light trim to remove any dead or damaged leaves. Pruning encourages new growth and helps the plant adjust to its new indoor environment. Don’t cut more than one-third of the plant at once to avoid stress.
3. Repot if Necessary: If your herbs are in the ground or an outdoor container, repot them into a smaller container with fresh potting mix. Choose a pot with drainage holes to prevent waterlogging, which can be harmful indoors.
4. Acclimate Your Herbs: Herbs can be sensitive to sudden changes in environment, so it’s best to gradually acclimate them. Bring them indoors for a few hours each day over a week or two before fully moving them inside. This helps them adjust to the indoor humidity and light levels.

Indoor Care Tips for Hardy Herbs

Now that your herbs are indoors, follow these care tips to keep them thriving through the winter months:

1. Find a Sunny Spot: Most herbs need at least 6-8 hours of sunlight each day. Place them in a south-facing window or the brightest spot in your home. If you don’t have enough natural light, consider using a grow light to supplement.
2. Water Wisely: Herbs don’t like to sit in soggy soil, so let the soil dry out slightly between waterings. Water thoroughly until it drains from the bottom of the pot, but don’t let your herbs sit in standing water.
3. Humidity Matters: Indoor air can be dry in winter, but herbs love humidity! Mist your herbs regularly or place a tray of water with pebbles nearby to increase humidity levels. You can also group your herbs together to create a micro-humid environment.
4. Keep an Eye on Temperature: Herbs prefer a temperature range of 65-75°F (18-24°C). Avoid placing them near drafty windows or heating vents, as sudden temperature changes can cause stress.
5. Fertilize Lightly: Since herbs grow more slowly in winter, they don’t need as much fertilizer. Feed them once a month with a diluted, balanced liquid fertilizer to keep them healthy.

Harvesting Your Indoor Herbs

One of the best parts of overwintering your herbs is that you can continue harvesting them throughout winter! Here’s how to do it without harming the plant:

• Harvest no more than one-third of the plant at a time.
• Always snip from the top or outside of the plant, which encourages new growth.
• Use sharp scissors to make clean cuts and avoid damaging the plant.

Herbs That Can Stay Outdoors with Some Extra Care

If you have a garden with hardy herbs like sage, mint, or chives, these can often survive outdoors with a bit of help:

• Mulch: Add a layer of mulch around the base of your outdoor herbs to insulate the roots from freezing temperatures.
• Covering: Use burlap or frost cloths to protect your herbs from frost on extremely cold nights.

What to Expect in Spring

As winter winds down, your indoor herbs might start to look a little leggy or less vigorous. This is normal! Once the danger of frost has passed in spring, you can begin to re-acclimate your herbs to the outdoors, just like you did when you brought them inside. Gradually increase their time outside until they’re ready to be transplanted back into the garden.

Enjoy Fresh Herbs All Winter Long!

Overwintering your hardy herbs is a simple and rewarding way to keep the flavors of summer alive during the colder months. With just a bit of care, your indoor herb garden will thrive, and you’ll have a steady supply of fresh rosemary, thyme, and oregano to elevate all your winter dishes. So, don’t let your herb garden go dormant – bring it inside and enjoy the green goodness all year long!
