Harvest your herbs

Your first instinct might be to just hack down every little bit of greenery that’s left on your herb plants. Before you do, note that some herbs are perennial and some are annual. Annual herbs such as basil and cilantro will typically die off in cold winters. Biennials such as dill and parsley may come back next season, but they are typically grown and harvested as annuals. Perennials such as thyme, oregano, mint, and sage can often survive a winter, depending on the variety, how cold your winters get, and the soil conditions. Since annuals die off in winter, you might opt to harvest them out completely when freezes are in the forecast.

You might also be tempted to hack back your perennial herbs to harvest as much as you can, but you’ll want to proceed more cautiously. While perennial herbs can benefit from pruning in late summer several weeks before your first frost, if you harvest aggressively before winter they might not be able to heal and come back next season. Don’t cut too far down on the stems and don’t remove a significant portion of the plant.

Harvesting your herbs is probably the simplest approach (other than doing nothing), but you’ll likely end up with a glut of herbs to use up. Try drying your excess herbs or chopping them up and freezing them in ice cube trays topped off with water or oil.

Save herb seeds

If your herb plants have formed mature seed heads, take advantage and save seeds for next season! Dill, cilantro, and parsley are all examples of herbs that are fairly easy to save seed from. To save seeds from your herbs, be sure the seed pods on the plant are fully mature- they should be light brown, not green. Cut off the seed heads and allow them to fully dry out before storing them (this can take up to a couple weeks). Remove the fully dry seeds from the heads, then store them in paper sachets, airtight containers, or plastic baggies and label them with the plant/variety and the year.

Cover your herbs

Herbs can be surprisingly cold-hardy, with some notable exceptions such as basil. If you cover your herbs with row cover or clear plastic sheeting you can potentially keep harvesting them into winter. Annuals can still die off if temperatures drop too low, but covering them offers a few degrees of frost protection that can let you keep harvesting them just that little bit longer. Perennials often keep their leaves through winter- so long as they are accessible under the cover and you have the willingness to get out there, they can potentially be lightly harvested through winter. Even if you don’t intend to harvest them in winter, covering your perennial herbs, along with applying a thick layer of organic mulch, can help increase their chance of survival.

Bring herbs indoors

If your herbs are growing in containers you might be able to easily transition them indoors. In fact, it may be best to bring them indoors as even hardy perennial herbs may not survive freezing temperatures outside in a container. If you do bring your container herbs inside, check the plants thoroughly for pests and consider refreshing the soil to avoid bringing in unwanted houseguests. Otherwise, you can take cuttings from your herbs and root them in water (this works well with basil, oregano, rosemary, sage, and thyme to name a few). Herbs prefer full sunlight so to grow them indoors you’ll want to consider using grow lights to keep them as healthy as possible. If your herb cuttings fail to take root all is not lost- just start new herbs from seed as a fun indoor winter project!

Do nothing

Last but not least, you can simply let nature take its course. Without any extra effort you might find that your herb garden mostly bounces back come spring. Perennial herbs can make a comeback, semi-tender herbs might surprise you with their resilience, and some herbs might have self-seeded so you get brand-new plants as soon as the weather warms up! As mentioned, keep in mind that herbs left in containers outside are less likely to survive winter unaided (depending on the size of the container and the temperatures). Also be aware that some herbs, such as lavender, are fairly cold-hardy but will rot and die if they are left in wet, poorly-drained soil. Doing nothing is a bit of a gamble, but if you happen to end up with holes in your herb garden next season consider it an excuse to try growing some brand-new herb varieties!

Herbs can be sturdy winter warriors, but they are not all created equal! Decide what you want to do with each plant as the snow approaches, then hunker down and start planning in Planter for an abundant herb garden next year!

Why Add Herbs to Your Garden

Herbs pack a major flavor punch in a dainty package and greatly enhance any dish you add them to. The price of fresh herbs at the grocery store can make you flinch - ‘do I really need fresh thyme in that dish?’ But if you have a flourishing herb garden, you will be looking for new and creative ways to use them rather than shying away! Herbs also contain vitamins and minerals and offer many health benefits.

Most herbs are quite easy to grow. They can thrive in nutrient-poor soil and some even prefer to dry out slightly! And herbs benefit your garden overall- they are great companion plants that can help ward off pests and attract beneficial insects and pollinators.

How to Select Herbs for your Garden

The first thing to consider when deciding which herbs to plant is what herbs do you like to eat? If you don’t regularly enjoy eating it, don’t bother growing it (unless you are experimenting with something new!)

Some herbs, such as mint, are perennials that can come back every year. Some perennial herbs may not be able to withstand winter in your area though, so be sure to confirm that the specific varieties you select are hardy in your growing zone. There are also herbs, such as dill, that are prolific self-seeders that will likely regrow each year.

Perennial and self-seeding herbs can be an asset in your garden if they are planted in a convenient location. Be warned, though, that some of these herbs can take over your garden if they are not contained. Bear this in mind when choosing which herbs to plant and where to plant them.

How to Plant and Care for Herbs

Some herbs can be easily started from seed, and some can even be propagated from cuttings. Others can be more tricky to grow from scratch, but buying herb plants from your local garden center still provides a great return on your investment.

Generally, herbs prefer a full-sun location and very well-draining soil. If you are growing in heavy clay soil it will need amending with compost and sand. Different herbs can have unique preferred growing conditions, however. Even though it looks enticing to plant a variety of herbs together, check their unique growing needs in Planter and avoid grouping herbs with very different needs in the same space.

You may opt to grow herbs in containers to have better control of the growing conditions. Planting herbs in containers also has the advantage of helping to control spread (except for rogue seeds!) If you do plant your herbs in containers, be sure they have drainage holes or use fabric pots that allow excess water to drain. You will need to water herbs in containers more often than if they were planted in the ground or in larger raised beds. Containers will also need extra care over the winter. Bring them into a garage or shed to help protect them, and bear in mind that perennial herbs will be less winter-hardy if they are grown in containers.

Regardless of whether you plant in-ground or in containers, it helps to have your herbs in a location that is handy to the kitchen. Otherwise you might not be inclined to go harvest them when you are in the middle of cooking!

When it comes to caring for herbs often less is more. Many herbs do not like to be overwatered and prefer to dry out between waterings, and as a general rule herbs need minimal fertilizing. There are always exceptions though, so be sure to check Planter for watering and fertilizing recommendations for the herbs you grow.

When your herbs are ready to harvest, don’t be afraid to give them a haircut! Herbs thrive with a regular trim; it helps them be more productive. Just don’t cut away more than one third of the plant at once. Check out the harvesting and storage tips in Planter to get the most out of your herbs:
