Creeping thyme is not only a stunning addition to any garden but also has various culinary and medicinal uses.

If you’re looking to add this versatile and attractive plant to your garden, one of the most popular ways to propagate creeping thyme is through seeds.

Step 1: Choosing The Right Time

Creeping thyme seeds can be sown either in the spring or fall, depending on your region’s climate. It’s generally recommended to sow the seeds in early spring to give them a chance to establish before the hottest summer months. If you live in a region with mild winters, sowing in the fall is also a viable option.

Step 2: Soil Preparation

Before sowing the seeds, it’s essential to prepare the soil properly. Creeping thyme prefers well-draining soil with a slightly alkaline pH of around 7.0. Start by removing any weeds or debris from the planting area. Loosen the soil using a garden fork or tiller to a depth of about 6 inches (15 cm).

Step 3: Sowing The Seeds

Creeping thyme seeds are tiny, so it’s best to mix them with a carrier material such as sand or vermiculite to ensure even distribution. This will prevent overcrowding as well. Moisten the carrier material, and then sprinkle the seeds over the prepared soil, pressing them gently into the surface using your fingers or a light roller.

Step 4: Covering And Watering

After sowing the seeds, lightly cover them with a thin layer of soil, no more than 1/8 inch (3 mm) thick. Excessive covering can prevent the seeds from germinating. Once covered, water the area gently to settle the seeds in place. It’s important to keep the soil consistently moist but not waterlogged during the germination process.

Step 5: Germination And Transplanting

Germination typically takes around 10 to 14 days, although it can vary. During this period, monitor the moisture levels and ensure the soil remains damp. Once the seedlings have grown to a height of about 2 inches (5 cm) and have developed their first true leaves, it’s time to thin them out.

Transplant the seedlings, leaving a spacing of about 8 to 10 inches (20 to 25 cm) between each plant. This will allow enough room for the creeping thyme to spread and fill in the gaps over time.

Part 2: Maintaining And Caring For Creeping Thyme Seedlings

Light And Temperature

Once your creeping thyme seedlings are transplanted, it’s crucial to provide them with the right growing conditions. Creeping thyme thrives in full sunlight, receiving at least six hours of direct sunlight per day. Ensure that the seedlings are placed in a location that offers ample sunlight exposure.

Regarding temperature, creeping thyme is hardy in USDA zones 4 to 9. It can tolerate a wide range of temperatures, but it prefers moderate to cool climates. If you live in an area with scorching heat, provide some afternoon shade to protect the plants from excessive sun exposure.


While creeping thyme is relatively drought-tolerant, it’s important to keep the seedlings evenly moist during their initial establishment period. Water the plants thoroughly whenever the top inch (2.5 cm) of soil feels dry. It’s best to water deeply and infrequently to encourage the roots to grow deeper into the soil.


Creeping thyme doesn’t typically require heavy fertilization. However, if your soil is poor in nutrients, you can apply a well-balanced, slow-release organic fertilizer during the growing season. Follow the manufacturer’s instructions for application rates, but generally, a single application in spring is sufficient.


Applying a layer of organic mulch around the seedlings can help conserve moisture, suppress weed growth, and regulate soil temperature. However, be careful not to mulch too close to the base of the plants, as it can trap too much moisture and potentially rot the stems.
