Choosing the Best Thyme Variety
With over 350 varieties of thyme, it can be difficult to select the type that is best suited to your climate, available space, and personal preferences. Here is an overview of some of the most popular options:
Common Thyme
The most popular variety, common thyme (Thymus vulgaris), is characterized by its strong, earthy flavor and green-gray leaves. It grows up to 12 inches tall and does well in hot, dry conditions. Common thyme works nicely for most culinary applications.
Lemon Thyme
As the name suggests, lemon thyme (Thymus citriodorus) has a distinct lemony fragrance and flavor. Its green leaves brighten both sweet and savory dishes. Lemon thyme reaches a petite height of 5 inches, making it a great choice for containers.
Caraway Thyme
Caraway thyme (Thymus herba-barona) stands out for its licorice-like caraway seed flavor. It works well when cooking robust foods like stews, sausages, and breads. Caraway thyme has fuzzy green leaves and grows up to 8 inches tall.
Creeping Thyme
Creeping thyme (Thymus serpyllum) is a low-growing variety that spreads in mat-like tufts. Its tiny leaves lend a mild flavor to recipes while its purple flowers create lovely ground cover in gardens and rock gardens. Creeping thyme only grows 2-4 inches tall.
When selecting your thyme type, consider your growing zone, sunlight availability, flavor preferences and garden design goals. Herb specialists at local nurseries can further assist with recommendations.
Providing Optimal Growing Conditions
One of the keys to growing strong, healthy thyme plants lies in providing the proper growing conditions from the start. Here is an overview of what thyme needs to really thrive:
Sunlight
As a Mediterranean herb, thyme requires full sun exposure. Choose a planting area that receives at least 6-8 hours of direct sunlight daily. This enables the plant to grow bushy and develop its essential oils.
Soil
Well-drained soil with a neutral pH around 7.0 provides ideal conditions for thyme. Improve drainage in dense clay soils by mixing in 1-2 inches of organic compost or peat moss. Container gardeners can use a quality potting mix.
Water
Allow the soil to dry out moderately between waterings. Overwatering encourages fungal root diseases. Use a drip irrigation system or water at the soil level rather than overhead. Inconsistent moisture also negatively impacts thyme growth.
Air Circulation
Good airflow enables thyme leaves to dry out after rainfall or watering. This helps prevent foliage diseases. Proper airflow also stabilizes temperatures.
Pruning & Weeding
Prune thyme bushes by one-third each spring to remove woody growth and stimulate the emergence of new leaves. Clear away surrounding weeds so thyme won’t have to compete for space, nutrients or moisture.
Planting Thyme for Success
Ready to add thyme to your indoor or outdoor living space? Here is a step-by-step planting guide:
Start Seeds or Buy Transplants
The quickest way to get growing is to purchase young thyme plants from a nursery. For more variety or savings, you can start seeds indoors or outside 2-3 weeks before your region’s final frost date.
Prepare the Planting Area
Select a site with full sun access and well-draining soil. Remove weeds/debris. Work 1-2 inches of finished compost into garden beds for added nutrients. For containers, use quality potting mix.
Dig Planting Holes
If planting an outdoor herb garden bed, use a trowel to dig holes 12-18 inches apart and just wider/deeper than each plant’s root ball. This allows room for spreading.
Place & Backfill
Carefully place each young thyme plant in its hole with the top of the root ball level with the ground. Fill holes with surrounding soil, firming it gently around stems with your hands.
Water Well
Water both outdoor and container thyme plants at their bases until soil is moist but not soaked. Proper watering encourages root growth as plants establish themselves. Protect new transplants from harsh sun/wind with cloches.
Add Mulch
Once planted, apply 1-2 inches of organic mulch around thyme bushes to help retain soil moisture and regulate temperatures. Suitable mulches include wood chips, straw or pine needles. Replenish as needed.
Caring for Thyme Over Time
Keep your thyme plants healthy and increasing in flavor by attending to the following care needs:
Watering
Mediterranean herbs like thyme thrive on infrequent but deep soakings. Check soil moisture 1 inch down before watering. Let it dry moderately between drinks.
Sunlight & Space
Ensure thyme receives full sun. The bushy plants reach 12-24 inches across when mature. Space them accordingly or trim yearly to contain spreading.
Soil Nutrients
Apply organic All-Purpose fertilizer every 2-3 weeks during spring through mid-summer. Thyme has relatively low nutrient requirements but benefits from an occasional feeding.
Pest Management
Watch for tiny pests like spider mites or spittle bugs which can slow growth. Remove by hand or use insecticidal soap. Avoid chemical pesticides which taint flavor.
Pruning
Trim back 1/3 of the bush each spring to encourage new growth. Snip away any dead branches or leaves through the seasons to keep plants fresh.
Overwintering
In zones 5-9, thyme remains evergreen through winter. Elsewhere, mulch roots to insulate or pot up plants to overwinter indoors until threat of spring frost passes.
Harvesting Thyme All Season Long
One of the greatest rewards of growing thyme is harvesting those flavorful leaves for kitchen creations all year long. Follow these handy tips:
When to Harvest
Begin harvesting thyme when plants reach 6 inches tall. For the highest essential oil concentrations, cut sprigs in the morning after dew dries.
How to Harvest
Use clean, sharp gardening shears or scissors. Cut sprigs back by up to one-third any time from early summer through fall frosts.
Harvesting Best Practices
Start at the top of each stem and trim back 4-6 inches to allow for regrowth. Gently handling leaves also retains more oils.
How Much to Harvest
As a rule of thumb, do not remove more than one-third of any plant during a single cutting to ensure ongoing growth.
Preserving Thyme
Rinse harvested sprigs and dry them slowly on screens or by hanging upside down in small bundles. Store thoroughly dried leaves in airtight glass jars to protect potency.
Regrowing from Cuttings
Take 4-6 inch thyme cuttings to root in water or potting mix over winter. Transplant the young plants outdoors in spring for free additions!
Cooking and Baking with Homegrown Thyme
Adding homegrown thyme to your recipes imparts a delightful earthy, herbal quality unlike anything dried thyme can offer. Here are some ideas for savoring fresh thyme from garden to table:
Thyme Roasted Chicken – Season a whole chicken inside and out with minced thyme, lemon, garlic and olive oil before roasting. The thyme perfectly complements the rich chicken juices.
Thyme Infused Vinegars – Gently bruise fresh thyme sprigs to release their oils and add them to wine or cider vinegars. Infuse for 1-2 weeks before removing thyme. Makes a wonderful salad dressing base.
Focaccia with Thyme – Sprinkle fresh leaves over dough before second rise when making focaccia, allowing their scent to permeate the bread. Add more thyme on top just before baking.
Lemon Thyme Tea – To make a refreshing herbal tea, pour boiling water over 3-4 fresh lemon thyme sprigs or 2 teaspoons dried leaves. Steep for 5+ minutes before straining out leaves. Sweeten lightly if desired. Sip to ease coughs or nausea.
Thyme Pesto – For a twist on traditional Basil pesto, substitute 2 cups of fresh thyme leaves for the basil. Process with garlic, olive oil, nuts and cheese. Toss with pasta or spread over chicken breasts.
Thyme Butter – Blend chopped fresh thyme into softened butter. Form into a log, wrap in waxed paper and chill before slicing off patties to melt over steaks, corn on the cob or baked potatoes for herbal flavor.
Get creative with homegrown thyme! Its grassy, floral notes enliven breads, meats, vegetables and more. Preserve abundance through drying or freezing too.
Growing Tips for Thyme Success
Follow these key suggestions for thriving thyme bushes that will bring impressive flavor to your cooking:
- Give thyme at least 6 hours of full sunlight exposure every day
- Limit fertilizer to 1-2 light feedings per year
- Trim plants back by one-third periodically to encourage bushy growth

Frequently Asked Questions About Growing Thyme
Whether you are new to gardening with herbs or already have some experience, questions may arise regarding the keys to growing flavorful thyme. Here are helpful answers to some of the most common inquiries:
Where is the best place to plant thyme outdoors?
Choose a sunny spot with well-draining soil. In cooler climates, locate it next to a stone wall or rock garden which radiates warmth and provides shelter.
Should I start thyme from seed or buy starter plants?
For faster harvests, buy young potted thyme plants so you can skip the seed starting/germination process. Starting from seed does allow you to choose from a wider variety of thyme types though.
What is the ideal spacing between thyme plants?
Space thyme plants 12-18 inches apart. This prevents overcrowding while still creating a bountiful herb garden. Thyme spreads as it matures but does not self seed aggressively.
How much water does thyme need?
Thyme prefers consistent moisture but soil should not remain soggy. Allow the soil surface to dry out moderately between occasional deep soakings. Use drip irrigation for water-wise watering.
When should I fertilize my thyme plants?
Fertilize thyme lightly every 2-3 weeks during the active growing season in spring through mid-summer. Discontinue feeding in late summer through winter when growth naturally slows. Use an organic all-purpose or herb fertilizer following package instructions.
What pests commonly affect thyme?
Watch for tiny spider mites which thrive in hot, dry conditions. Also be on the lookout for spittle bugs. Both pests can slow growth but are fairly easy to control manually or with insecticidal soap.
Can I grow thyme indoors?
Yes! Thyme also adapts nicely to life as a houseplant. Place your thyme pot in a sunny south facing window and water only when the top inch of soil is dry. Rotate the pot weekly so sunlight exposure remains even. Prune mature plants as needed to maintain an ideal compact size.
How do I get bigger thyme plants?
Prune back thyme bushes by one-third their size in early spring. This stimulates the growth of new leaves and branches resulting in a thicker, bushier appearance by mid to late summer. Plant your thyme specimens in rich soil amended with compost or manure and water deeply.
What is the best way to dry thyme for storage?
Rinse freshly harvested thyme sprigs and gently shake off excess moisture. Air drying is recommended over using a dehydrator to retain the highest quantity of essential oils which impart flavor. Hang small thyme bundles or place loose sprigs in a single layer on a mesh screen in a warm, shady spot with good airflow. Once the leaves crumble easily, after about 1 week, transfer to airtight glass jars and store away from direct light.
How late in the year is thyme usually harvested?
In most regions, thyme can be harvested through the late fall right up until the first damaging frost of winter as long as plants have sufficient foliage left to maintain their vigor. Make your final harvest cuts just as cool weather sets in. Discard any battered plants after winter passes, as they will not recover. Healthy thyme bushes will return year after year once established.
