Creeping Thyme: Tips for Growing and Maintaining this Low-Growing Groundcover Plant

Creeping Thyme (Thymus Serpyllum) is one of the several woody-stemmed perennial species of the Thymus genus that are good ground covers for sunny areas and landscape designs. It is a perennial herb that will over-winter well in zones 4-9 and prefers well-drained soil with a neutral pH between 6.5 and 7.5 in an area where it can receive good sun but can also tolerate partial shade.

Creeping Thyme is principally grown for the delicate texture of its leaves as they spread out to softly blanket the ground. They can also produce flowers of various colors depending on the type. Its flowers usually appear in late spring and early summer from established plants.

How To Grow Creeping Thyme

Creeping Thyme is tolerant of drought conditions, but water-logged soil is harmful to its production and survival. It grows best in warm, sunny climates at temperatures between 4 and 28°C (39.2 – 82.4°F), but it will grow best at 16°C (60.8°F).

Creeping Thyme will thrive best in well-draining fertile Sandy loam or sand and should be planted in alkaline soils with full sunlight for optimum productivity. You can grow Creeping Thyme in three methods: division, stem cuttings, and seeds.

How To Grow Creeping Thyme By Division

Before starting, make sure you use this method in either spring or fall for a smooth re-establishment. Results have proven that the warmer weather and longer spring days help the plant increase and gain new growth. While in fall, the plants tend to huddle and invest more energy in their roots.

1 . To get started, select a plant you have watered recently. Use a pot with at least 3 inches of growth on all sides and below the plant.

2.  Dig around the plant in a circle about 3 to 4 inches from the center of the plant. Careful not to cut through the roots, and if you do, it’s beautiful.

3.  Go ahead and divide. Cut through the middle of the plants keeping the roots intact. As long as you have healthy roots, make multiple cuts. If you have old soil around your plant’s roots, shake it off.

4.  Put your soil at the bottom of the pot and center the plant in the middle. Make sure the plant has the same soil line as before. Add soil around all sides of the root ball and add water until you see water run out the bottom.

Be careful not to let the soil appear soggy. Go ahead and place it in a sunny location.

How To Grow Creeping Thyme From Stem Cuttings

Equipments needed

  • Healthy non-flowering stem with new leaf growth.
  • I sterilized scissors or pruners.
  • Fresh well-draining soil.
  • Clean pot.
  • Rooting hormone (Optional)
  • Sunny Pot (Optional)

1 . Cut the stem 4 to 6 inches long and remove the bottom 2 inches of leaves. If you are using rooting hormone, Go ahead and apply it to the cut end of the stem.

2.   If you are not using rooting hormone, develop the roots in a clean, clear glass of filtered water. Place the cutting in a sunny Pot and wait till new roots develop. Roots development can take up to three-four weeks.

3. With Rooting Hormone in place, plant the stem cutting in the center of the new container with fresh soil. Place the plant in a sunny Pot and water it to keep the soil consistently moist by not being soggy.

How To Grow Creeping Thyme From Seed

You can grow Creeping Thyme from seed either indoors, in the greenhouse, or outdoor after the danger of frost has passed. Plant the seeds on the soil’s surface with a light covering the soil. The seeds germinate for seven to twenty-one days at 65 to 70°F.

To moisten the top of the soil, use a spray bottle, and once the seedlings have 3 to 4 inches of growth, you can transplant them into a new container or plant them in the ground after the danger of frost has passed.

How To Care For Creeping Thyme

Creeping Thyme will thrive in excessively clay Sandy soils. It will grow between 2-3’high, and each established plant can spread approximately 1’wide.

It is hardly a plant that doesn’t have any problems, although, like many other plants, it is susceptible to root rot in wet-soggy soil.

1 . Light

Creeping Thyme thrives in full sun, though it can tolerate partial shade.

2.  Water

Creeping Thyme is reliably drought-tolerant once established. Water new plants regularly until they are established. 

3. Temperature And Humidity

Creeping Thyme doesn’t like humidity. Prune the thyme as needed to keep it bushy and dense.

4. Fertilizer

Creeping Thyme that grows in well-prepared soil shouldn’t be fed. If the soil is poor, you can provide a delayed-release fertilizer at the beginning of the growing season.
