Why Thyme? A Hardy Perennial with Big Flavor
Thyme is a perennial herb that’s perfect for both novice and seasoned gardeners. This hardy perennial requires little maintenance and thrives in poor soil, making it ideal for rock gardens, small spaces, or even as a ground cover in your vegetable garden. From French thyme to caraway thyme, culinary thymes add different flavors to your dishes, while woolly thyme or creeping thyme can handle light foot traffic on your garden path. Plus, thyme’s tiny flowers attract pollinators, giving your garden a boost during the summer months.
In general, thyme isn’t an invasive type of herb in spite of being part of the mint family. (Mint on the other hand is quite invasive so it’s best to keep in contained.
Are all types of thyme edible? Yes! All types of thyme are in fact edible. However, some are better suited for culinary purposes.
When’s the Best Time to Plant Thyme Seeds?
Timing is everything! For most climate zones, the best time to plant thyme seeds is late winter or early spring, around half April, to give your young plants a head start before the growing season. If you’re in a region with an extreem droog voorjaar, consider starting your seeds indoors in a small pot to protect them from harsh conditions. You can also direct sow thyme seeds in late spring or early summer after the last frost, ensuring warm weather for new growth.
Pro tip: Start your seeds indoors 6-8 weeks before the last frost for stronger thyme seedlings. This is especially helpful for culinary herbs like Thymus vulgaris or lemon thyme. Although you can definitely start seeds outdoors and they’ll grow really well.

Choosing the Right Spot: Full Sun and Well-Drained Soil
Thyme plants love full sun and free-draining soil. Whether you’re planting in garden soil or a small pot, make sure your grow spaces have good drainage to prevent root rot and fungal diseases. Thyme thrives in well-draining soil with a bit of organic matter, but it’s tough enough to handle poor soil conditions. In my garden, I have it planted in a half mini wine barrel which you can get at just about any major gardening center. It’s been thriving in there for the past 3 to 4 years (whenever I planted it). If you have less than ideal soil, that’s ok. Thyme is a pretty hardy plant, but to prevent any sort of issues, amend your soil. As I’ve mentioned in numerous posts, my favorite is cow manure and I buy Black Kow.
For a playful touch, try planting ground cover thymes in rock gardens for a whimsical, low-maintenance look. Partial shade is okay for some varieties like woolly thyme, but full sun brings out the best in most thyme plants.
How to Plant Thyme Seeds: Step-by-Step
Ready to get your hands dirty? Here’s the best way to plant thyme seeds for a flourishing herb garden:
- Prepare Your Soil or Pot: Use well-drained soil with good air circulation. A small pot with drainage holes works great for indoor starts. Having drainage holes in your pot is SUPER important. You want the water to drain out so the roots aren’t sitting in soil. Add a bit of organic matter for a nutrient boost, but don’t overdo it—thyme loves lean conditions.
- Sow the Seeds: Scatter thyme seeds lightly on the surface and cover them with a thin layer of soil. Press gently to ensure contact, but don’t bury them too deep—these tiny seeds need light to germinate. If they’re sown too deep, they may have a really hard time germinating. With really small seeds, you’ll find that they’re just barely covered with soil.
- Water Sparingly: Thyme seeds need little water to sprout. Keep the soil slightly moist but never soggy to avoid fungal diseases. Too much water can lead to root rot, so go easy!
- Provide Warmth and Light: Place your pot or tray in a sunny spot or under grow lights. Thyme seeds germinate best in warm weather, around 70°F (21°C).
- Be Patient: Germination can take a long time—sometimes 14-28 days. Keep the faith, and soon you’ll see new growth from your thyme seedlings.
If you’re new to gardening, you’ll find that patience is a common theme and lesson. Growing any type of food isn’t instantaneous.
Caring for Young Thyme Plants
Once your thyme seedlings sprout, they’re on their way to becoming mature plants! Here are some growing tips to keep them healthy:
- Watering: Water sparingly, as thyme plants prefer dry conditions. Let the soil dry out between waterings to prevent root rot. Since mine are in a mini half wine barrel type pot, the soil dries out pretty quickly. In all honesty, I’m pretty neglectful of my thyme.
- Thinning: If you’ve direct sown, thin your young plants to 6-12 inches apart to ensure good air circulation and room for their woody stems to spread.
- Pests and Diseases: Watch out for spider mites, especially in hot, dry weather. A quick spray of water can keep them at bay. Ensure good drainage to avoid fungal diseases.
- Pruning: Once your thyme plants are established, trim the tips of the stems to encourage bushy growth. Harvest thyme regularly to keep the plant vigorous.
Harvesting and Using Thyme
By early summer or late summer, your thyme plants will be ready for their first harvest. Snip the tips of the stems, leaving the woody stems and root ball intact to ensure the parent plant keeps growing. Use fresh thyme in your culinary creations or dry thyme in an airtight container for year-round flavor. It’s truly the best to have fresh thyme on hand, or having a jar with dried thyme so you don’t have to worry about running to the store. From soups to roasted veggies, thyme’s aromatic leaves elevate any dish. Try lemon thyme in desserts or caraway thyme in hearty stews for a twist!
For a fun project, propagate cuttings from mature plants in early fall to create new thyme plants for next year’s herb garden. It’s a great way to expand your collection of culinary herbs without buying more seeds.
Thyme Varieties to Try
Not sure which thyme to grow? Here are some favorites for your eetbare tuin or rock gardens:
- Common Thyme (Thymus vulgaris): The go-to for culinary uses, with robust flavor.
- Lemon Thyme: Bright, citrusy notes perfect for fish or desserts.
- Creeping Thyme (Thymus serpyllum): A low-growing ground cover for paths or rock gardens.
- Caraway Thyme: Earthy and unique, great for breads and meats.
- Woolly Thyme: Soft, fuzzy leaves for ornamental grow spaces.
Troubleshooting Common Thyme Problems
Even with little maintenance, thyme can face a few challenges. Here’s how to tackle them:
- Yellowing Leaves: Often a sign of too much water or poor drainage. Adjust your watering and ensure well-drained soil.
- Spider Mites: These pests love dry conditions. Mist your plants occasionally to deter them.
- Fungal Diseases: Prevent these by ensuring good air circulation and avoiding overwatering.
- Groene Aanslag: If algae forms on your soil surface, improve drainage and reduce watering.
Thyme in the Winter Months
Thyme is a hardy perennial, but it needs a little TLC in colder climate zones. Mulch around the base of mature plants to protect the root ball during winter months. If you’re growing in pots, bring them indoors or place them in a sheltered spot to avoid freezing. For an early start next season, sow seeds in late winter indoors to beat the last frost.
Why Thyme is a Home Gardener’s Dream
Thyme is more than just a culinary herb—it’s a low-maintenance, versatile plant that thrives in small spaces, rock gardens, or even as a ground cover. Its ability to grow in poor soil with little water makes it an excellent choice for any home gardener. Plus, thyme’s tiny flowers and aromatic leaves add beauty and fragrance to your garden all season long. The bees love the flowers so much so it’s a great way to support pollinators!
So, what are you waiting for? Grab your thyme seeds, find a sunny spot, and start planting! Whether you’re growing Thymus vulgaris for its culinary uses or Thymus serpyllum for its creeping charm, you’re just a few steps away from a thriving herb garden.
