Thyme to grow: A simple guide to fresh herbs at home

Growing herbs at home allows people to enjoy fresh flavors in their cooking and add a touch of nature to their space. However, some herbs can be difficult to grow at home due to their special needs. For example, basil and cilantro need warmth and humidity, which can be hard to provide indoors. These challenges can make it hard for beginners to start growing herbs.

Thyme, on the other hand, is one of the easiest herbs to grow at home. It is known for its rich, pleasant flavor and is very adaptable. It can grow in many different environments, whether in a garden, on a windowsill, or in a small pot. It can thrive in various soil types and weather conditions, making it a great choice for people new to gardening or with limited space.

Growcycle provides high-quality thyme seeds, such as the Wetsel Seed™ Thyme Seed 175mg Packet, known for its strong, clove-like aroma and flavor.

Botanical Description

Thyme (Thymus vulgaris) is a small, woody herb in the mint family, Lamiaceae. Native to the Mediterranean, it is now widely cultivated worldwide.

• Physical Characteristics

Thyme is a low-growing plant with small, narrow, aromatic leaves. They are generally green, though some varieties may have a silver or purple tint. The leaves are about 1–2 centimeters long and have a delicate texture that contributes to thyme’s distinct aroma.

• Growth Habit

Thyme has a compact, bushy growth habit and typically reaches heights of 6–12 inches. The base of the plant is woody, while the upper parts of the stems remain more flexible. The plant produces tiny flowers that can be pink, purple, or white, blooming in clusters from late spring to early summer. These flowers attract pollinators like bees.

• Root System

The root system of thyme is shallow but sturdy, which helps the plant grow in well-drained, dry soils. It can thrive in poor soil conditions and is resistant to drought, making it a hardy herb.

• Aromatic Qualities

One of its key features is its fragrant aroma, which is released when the leaves are crushed. This scent is due to essential oils, particularly thymol, which also gives thyme its characteristic flavor.

• Perennial Nature

Thyme is a perennial herb that can live for several years. It prefers full sunlight and slightly alkaline to neutral soil. Its ability to tolerate various temperatures and growing conditions makes it a favorite for both beginner and experienced gardeners.

Different Types of Thyme

Thyme comes in many varieties with unique characteristics that make it suitable for different growing conditions, uses, and flavors. Here are some of the most common and popular types of thyme:

Factors to Choose the Right Variety of Thyme

Choosing the right variety of thyme depends on several factors, such as the space available, the climate, the intended use, and personal taste preferences. Here are some key factors to consider when selecting the best thyme variety for the garden or home:

1. Taste and Culinary Use

Each type of thyme has a distinct flavor. For example, common thyme has a strong, savory flavor, making it ideal for hearty dishes like stews and roasts. Lemon thyme, on the other hand, offers a citrusy, refreshing flavor that pairs well with seafood or salads.

2. Growth Habits and Space Requirements

Some thyme varieties grow upright, while others spread along the ground. If growers have limited space or want a plant that doesn't require much pruning, creeping thyme or woolly thyme might be ideal, as they grow low to the ground and make great ground covers.

If growers are growing thyme indoors, they need to choose smaller varieties that can thrive in pots or containers. Lemon thyme and silver posie thyme are excellent for small spaces like windowsills or balconies. For larger outdoor spaces, common thyme or creeping thyme can spread and fill larger garden areas.

3. Climate and Hardiness

Thyme is generally a hardy herb, but different varieties have varying tolerance levels to cold and heat. Common thyme is very adaptable and can thrive in both warm and cooler climates. Lemon thyme and orange thyme prefer warmer temperatures and may struggle in harsh winters.

All varieties of thyme require full sunlight to grow well, but the amount of sunlight they need may vary slightly. Based on the growing environment, ensure the chosen variety will get enough sunlight. Indoor varieties should be placed in bright, sunny spots, while outdoor varieties should be planted in locations with at least 6-8 hours of direct sunlight daily.

4. Size and Maintenance

Different thyme varieties vary in size. Common thyme typically grows between 12 and 18 inches tall, while creeping thyme stays much lower to the ground. If people have limited space or need a plant for a smaller area, consider a compact variety like lemon thyme or woolly thyme.

Most thyme varieties are relatively low-maintenance. However, if people are looking for a variety that requires less trimming and can cover more ground with minimal effort, creeping thyme or woolly thyme might be better choices. Common thyme is an excellent option if people want a variety that can be pruned regularly to maintain its shape.

5. Aesthetic Appeal

Thyme also adds beauty to gardens with its attractive foliage and small flowers. If people are looking for ornamental appeal, varieties like woolly thyme, with its silvery leaves, or creeping thyme, with its colorful blooms, can provide a lovely visual element. Silver Posie thyme, with its variegated leaves, is perfect for edging or decorative purposes.

Preparation to Grow Thyme

To grow thyme successfully, it is important to create the right environment. Thyme is a hardy herb, but it does best in certain conditions. Here is how to prepare the space for thyme:

1. Ideal Growing Conditions

Thyme needs full sunlight to grow well. It should receive at least 6–8 hours of sunlight every day. Place thyme near a bright window with plenty of sunlight if growing indoors. Without enough sunlight, thyme may become weak and grow poorly.

Thyme grows best in temperatures between 60 80°F (15 and 27°C). It can tolerate some cold but does not thrive in extreme winter conditions. In colder climates, it’s best to grow thyme in pots so it can be moved indoors during the cold months.

2. How to Select the Right Location

Thyme can be grown both indoors and outdoors. Indoors, it should be placed in a sunny spot, such as a south-facing windowsill. Outdoors, thyme needs a sunny garden spot. If space is limited, thyme can also grow well in containers.

Thyme can be planted in garden beds, raised beds, or pots. If there is limited space, containers are a good option, as they allow thyme to grow in a smaller space. Garden beds let thyme spread out more. Containers are especially helpful in areas with cold winters because the plant can be moved inside when needed.

3. Soil Preparation Tips

Thyme needs good drainage to prevent its roots from sitting in water. If the soil doesn’t drain well, add sand or perlite to improve drainage. Also, make sure the container has drainage holes to avoid water buildup in pots.

It prefers slightly alkaline soil with a pH of 6.0 to 8.0. Test the soil before planting. If the soil is too acidic, add lime to raise the pH. For pots, use a well-draining potting mix with a slightly alkaline pH.

Thyme doesn’t need soil that’s too rich in nutrients. Overly fertile soil can result in excessive leaf growth, which can reduce the flavor. Adding a small amount of compost to garden soil can improve its structure without making it too rich.

4. Choosing Containers for Indoor Growth

When growing thyme indoors, choose a pot that is at least 6–8 inches in diameter and has drainage holes. Avoid using very large pots, as thyme grows best when its roots are a little crowded. Clay or ceramic pots are good choices because they allow better airflow and drainage than plastic containers.

Make sure the container drains well, as thyme does not like standing water. Adding a gravel layer at the pot's bottom can help with drainage.

Planting Thyme: Step-by-Step Guide

Here is a step-by-step guide to help people plant thyme successfully:

1. Start from Seeds

Thyme can be grown from seeds, but it takes a bit longer. Start using seeds indoors about 6–8 weeks before the last frost. Use a seed tray with a light, well-draining seed mix.

Press the seeds gently into the soil, but don’t cover them too much, as thyme seeds need light to grow. Keep the soil moist and place the tray in a warm, sunny area. After about 2–3 weeks, when the seedlings are ready, they can be moved outdoors.

2. Proper Planting Techniques

Thyme needs full sunlight, so pick a sunny spot with at least 6–8 hours of direct sunlight each day. Whether planting in a garden or container, make sure the soil drains well. Space thyme plants about 12–18 inches apart to allow them to grow properly.

If planting in containers, the pot should be at least 6–8 inches deep and wide enough for the plant. Press them lightly into the soil when planting thyme from seeds, but don’t bury them too deep.

3. Watering and Fertilizing Tips

Thyme doesn’t need a lot of water. Water it deeply when the soil feels dry, but be careful not to over-water. The soil should drain well because thyme dislikes sitting in water. For container plants, make sure the pot has drainage holes to avoid water build-up.

Thyme doesn’t require much fertilizer. Too many nutrients can make the flavor less strong. A light amount of balanced fertilizer in the spring is enough. For thyme in containers, use a diluted liquid fertilizer every 4-6 weeks during the growing season. Avoid using too much fertilizer, as it can cause the plant to grow too tall and not produce strong-smelling leaves.

4. Pruning and Trimming

The best time to prune thyme is in the spring after the last frost and again in the fall before the plant goes dormant for winter. Use sharp scissors or pruning shears to trim thyme. Focus on cutting back any woody stems and removing spent flowers. Trim about one-third of the plant at a time to encourage fresh growth.

Suppose the thyme plant starts to look crowded or leggy; thin it by removing some of the older, less productive stems. This will allow the plant to focus its energy on the healthier parts.

5. Dealing with Common Issues

• Yellowing Leaves: Yellowing leaves can indicate over-watering or poor drainage. Thyme prefers dry soil, so check that the plant isn’t getting too much water. If the soil is too wet, allow it to dry out, and make sure the container or garden bed has good drainage.
• Wilting: Wilting can be caused by both over-watering and underwatering. It may need water if thyme is wilting and the soil is dry. If the soil is wet, the plant might suffer from root rot. Ensure the soil drains well and adjust watering practices.
• Leggy Growth: If the thyme plant becomes leggy (thin and stretched out), it may not be getting enough sunlight. Thyme needs 6-8 hours of direct sunlight daily. If it’s grown indoors, try moving it to a sunnier spot.

Harvesting Thyme

The best time to harvest thyme is when the plant is most fragrant and flavorful, typically just before it starts to flower. This is when the leaves are at their peak in terms of flavor and aroma. 

Harvest in the morning after the dew has dried but before the heat of the day sets in. This ensures the essential oils in the leaves are most concentrated. To harvest thyme without harming the plant, follow these steps:

• Cut the stems about 1-2 inches above the base of the plant. This encourages new growth and prevents damage to the root system.
• Avoid cutting too much of the plant at once. Only about one-third of the plant is removed, allowing it to grow and produce more leaves.
• Choose the healthiest, most mature stems to harvest. This allows younger, tender stems to continue growing.

Store Fresh Thyme

Once harvested, thyme can be stored in various ways:

• Refrigeration: Place fresh thyme sprigs in a glass of water like a bouquet for short-term storage. Cover them loosely with a plastic bag and store them in the fridge. This can keep thyme fresh for up to a week.
• Drying: Tie the stems together and hang them upside down in a cool, dry area. Once dried, remove the leaves and store them in an airtight container.
• Freezing: To store thyme leaves for long periods, wash and dry them, then place them in a freezer bag or container. People can also freeze them in ice cube trays with a bit of water or oil.
