It’s thyme to get growing! Whether you’re spicing up summer soups, grilling veggies, or adding fragrant greenery to your garden, thyme is a hardy, low-maintenance herb that’s as versatile as it is aromatic. Let’s dig in and see how to plant, grow, and harvest this little powerhouse of flavor.

About Thyme

A low-growing, hardy perennial, thyme is a fragrant herb with small, fragrant leaves and thin, woody stems. The culinary varieties are evergreen.

Thyme comes in over 50 varieties with different fragrances and flavors. Fresh or English thyme is used most often in cooking.

Originally from the Mediterranean area, this herb is drought-friendly, so it doesn’t have high watering needs. It is also pollinator-friendly! Let some thyme plants flower since the herb attracts the bees.

While thyme is usually harvested in the summer months, we have harvested ours well into late fall!

Thyme can grow in the ground or in a container. Either is left outside in the wintertime. New leaves will emerge within the early spring.

Planting

  • Thyme thrives in full sun and loves heat. If you are growing in a pot indoors, plant near a sunny window.
  • Soil needs to drain well so there aren’t “wet feet.” In the garden, plant with other drought-tolerant perennials.
  • In early spring, you may fertilize with organic matter, like compost, but not much soil amendment is necessary.
  • It’s hard to grow thyme from seeds because of slow, uneven germination. It’s easier to buy the plants from a garden center or take some cuttings from a friend. Over time, you can propagate from your own cuttings.
  • For a head start, plant the cuttings indoors 6 to 10 weeks before the last spring frost. (See your local frost dates.)
  • Plant cuttings or young thyme plants any time after the ground temperature reaches 70°F. This is usually 2 to 3 weeks before the last spring frost in well-drained soil about 9 inches apart.
  • Space young plants 12 to 24 inches apart, depending upon the specific variety.
  • The plants should grow 6 to 12 inches in height.
  • In the garden, plant thyme near cabbage or tomatoes.
  • If you are growing thyme in containers, plant with rosemary, which also likes sunny conditions and has similar watering needs.

Growing

  • Water deeply only when the soil is completely dry.
  • Prune the plants back in the spring and summer to contain the growth.
  • If you have cold winters, remember to lightly mulch around the plants after the ground freezes.
  • Three- to 4-year-old plants need to be divided or replaced because older plants are woody and the leaves less flavorful.
  • You can take some cuttings and plant them indoors in pots, too.

How to Take a Cutting of Thyme

Clip a 3-inch cutting from the very tip of a stem, apply rooting hormone on the exposed portion of the stem, and plant it in either sterile sand or vermiculite. Roots will emerge within about 6 weeks. Transfer to a small pot, let the root ball form, and then transfer to a large pot or directly to your garden.

Harvesting

  • Harvest thyme just before the plant flowers by cutting off the top 5 to 6 inches of growth. Leave the tough, woody parts.
  • It’s best to harvest thyme in the morning after the dew has dried. Clean leaves should not be washed because it removes some of the essential oils.
  • Two or more crops may be gathered during the season.
  • Or, if you keep trimming your thyme plant, it will keep growing (and also keep a compact shape). But always leave at least 5 inches of growth so the plant will continue to thrive.
  • Trim thyme whenever it gets leggy.
  • Fresh thyme should be stored refrigerated and wrapped lightly in plastic; it should last 1 to 2 weeks.
  • To dry thyme, hang the sprigs in a dark, well-ventilated, warm area. You can also just dry the leaves by placing them on a tray. Once dried, store them in an airtight container. Crush just before using. Under good conditions, herbs will retain maximum flavor for 2 years.
  • Freezing is another method of storage.

Hello almanac.com: Living in Pennsylvania where temperatures are currently in the 20-30 degree range, I've come by a thyme plant with a long, woody, root tht runs horizontaly to the plant. This root has multiple fine filaments where it meets the upright portion of the plant and further down has some single slightly thicker extensions which also might be roots. Anyway, I'd like to pot this herb for indoors, i.e. until spring arrives, and have the following questions: 1. What particular potting soil mix would best serve this purpose? 2. And/or would some dirt dug up from the back yard be just as good? 3. If the main root was trimmed for potting, leaving just the fine tendrils section ... could other pieces of this main root, i.e. those with the single extensions, be potted to produce other, separate, plants? -Thanks for any inputs.

I started my thyme seeds in April inside the house under LED lights 16 hrs on 8 hrs off. Sprouted in about 2 weeks now it does not appear to be growing at all. Some days it looks dry and other days it appears to be over watered.

i have a large bed full of thyme and it is flowering at the tips. can the flowers and seeds be eaten?

Yes, you can eat the thyme flowers: they are not only pretty but perfectly edible. If you want to avoid flowering, however, be sure to trim your herbs. Thyme will regrow if you trim only the very top inch of each branch. (Do not cut into old wood.) The plant may look a bit sparse, but it will sprout again as long as you don't overwater it.

Purple flowers have taken over my bed of Thyme. Do I use them in my cooking?

Hi Jeanne,

Yes, you can use thyme flowers in your cooking, to flavor butter or olive oil, or in salads.

I have German and English thyme in containers and noticed the leaves are very tiny and stringy stems. I usually cut them and dried for use in the winter. My ? is do I need to fertilize them. Thank you.

Is the thyme healthy looking, otherwise?  We usually like to start with a specimen that is stringy-looking to tie onto a frame. However, once you give the thyme plenty of bright light (6 to 8 hours) and fertilizer and water, the stems should start to get woody and stuff and self-supporting. Is the light bright enough? Is the soil moisture even, not soggy? Many people overwater herbs.

Herbs require minimal fertilization. In fact, herbs often suffer from overwatering and overfertilizing rather than from not enough. We like to amend with peat moss or any type of composted organic matter at planting but avoid fertilization after germination.
