Discover Culinary and Ornamental Thyme Varieties, Planting Tips, and Easy Care Guidelines

Written By: Catherine Boeckmann Executive Digital Editor and Master Gardener

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.

Types

The three most common varieties of culinary thyme are:

  • French or English thyme (most common)
  • Lemon thyme, for a hint of lemon
  • Caraway thyme, for a nice fragrance of caraway and thyme

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.

Cooking Notes

Thyme adds a gentle flavor to just about anything, especially eggs, tomatoes, meats, soups, beans, and potatoes.

Its taste has been described as a bit earthy with lemony and minty tones. Some think it has a slight floral flavor.

Fresh thyme can be used with or without its stem. However, if a recipe calls for a “sprig,” the stem should be left on. The leaves will fall off in cooking, and then the stem can be removed prior to serving.  

If a recipe calls for a “sprig” of thyme, the leaves and stem should be used together, intact. When adding a whole sprig of thyme to soups, stews, or other recipes, the leaves usually fall off during cooking, and the woody stem can be removed prior to serving.

I have a question. Can I grow thyme in Southeast Asia? Here the rain is to heavy every year.
<span>Eric K</span> Sun, 05/03/2015 - 10:26
I have thyme still growing from three years ago. I didn't expect it to survive the harsh winters here in New York. But they're thriving. And so is last years cilantro. My question is, are they still good to eat? I also have Brussels sprouts and broccoli that I planted in the fall and never got to harvest. They're also thriving now. Should I keep them? Or plant new seeds? Thanks if anyone can help..

Eric I am also in NY. Did you direct sow your seed? How much sun does your space get? How long did it take to germinate? I've direct sowed some and am now wondering whether to wait and see or just plant something else

Hi Eric, If you have old sprigs of thyme you may want to prune them back so that the plant will send up new growth this spring. The cilantro will probably develop flowers and then go to seed quickly when the warmer weather arrives. Plant some cilantro seeds for fresh new cilantro leaves.You can harvest your Brussels sprouts and broccoli any time. Leave the plants in the ground for more sprouts and broccoli side shoots to grow.

I recently planted thyme seeds in trays for indoor germination. I had real difficulty avoiding dropping the seeds in clusters as they are so very tiny. Any advice on the best way to get an even distribution?

This is a good question. Thyme seeds are indeed tiny! First, we would water before sowing fine seeds so they don't get washed away. When your seeds are very fine, open the packet over a piece of white paper. Then gently brush the seeds off the paper. You could also moisten the tip of a toothpick and use it to lift each seed. Once the seed is in the soil, we would just press it down gently so it's not buried too deeply.

try making homemade seed tape, use single ply toilet paper, put a small dab of thin flour/water slurry on the bottom half of the paper and put one seed and continue for as long as you wish, then fold over the paper to encase. you can bury the tape as deep as needed and it desolves

I have just started to garden and am questioning if I should harvest the English Thyme before it buds or after?

As long as thyme has greenery, you can harvest it.

I cannot grow thyme to save my life!!! I've tried creeping, English, German and I don't know what else?! I grow it in pots on the deck. I've tried sun, shade and half & half. I water it, it rots, I don't, it dries up.... What am I doing wrong???
