Understanding Lemon Basil for UK Gardens
Lemon basil (Ocimum basilicum 'Citriodorum') is a delightful herb that combines the classic sweet basil flavour with a vibrant citrusy lemon note. This makes it incredibly versatile in the kitchen, perfect for everything from salads and pasta dishes to teas and desserts. But what makes it suitable forgrowing lemon basil in the UK?
Lemon Basil Characteristics
- Flavour: Possesses a distinctive lemon-citrus aroma and flavour alongside the traditional basil notes.
- Appearance: Similar to other basil varieties, with bright green leaves, but the leaves are generally smaller and more pointed.
- Growth Habit: Typically grows to a height of 12-18 inches (30-45 cm).
- Hardiness: While not frost-hardy, lemon basil can thrive in the UK's warmer months. It's best treated as an annual.
Why Grow Lemon Basil in the UK?
Despite not being native, lemon basil thrives in the UK summer conditions, providing the following benefits:
- Unique Flavor: Add a special zing to your dishes.
- Aromatic: Its scent repels some pests, making it a beneficial companion plant.
- Easy to Grow: With proper care, it's a rewarding herb for beginner gardeners.
- Container Friendly: Perfect for small gardens or balconies.
Starting Your Lemon Basil Journey: From Seed to Seedling
You have two main options for starting your lemon basil: buying seedlings or starting from seeds. Starting from seed is more economical and gives you more control over the variety. Here’s a breakdown:
Starting from Seed
Starting lemon basil from seed is an easy way to obtain more of your own basil, which can also be more cost effective.
- Timing: Start seeds indoors 6-8 weeks before the last expected frost. In the UK, this is typically around March or April.
- Sowing: Sow seeds thinly in seed trays or small pots filled with seed-starting compost. Gently press the seeds into the soil, but don't bury them too deeply, as they need light to germinate.
- Germination: Keep the soil consistently moist, but not waterlogged. Cover the trays with a plastic dome or bag to create a humid environment. Germination usually takes 7-14 days at a temperature of 20-25°C (68-77°F).
- Pricking Out: Once the seedlings have developed their first true leaves (the second set of leaves), carefully transplant them into individual pots.
Buying Seedlings
Purchasing lemon basil seedlings from a garden centre or nursery is a convenient option, especially if you're short on time or don't have the space for seed starting. Choose healthy-looking plants with vibrant green leaves and no signs of pests or diseases.
Once your seedlings are established, it's crucial to gradually acclimatise them to outdoor conditions, a process known as hardening off. Expose them to increasing periods of outdoor time each day for about a week before transplanting them into their final location.
The Perfect Growing Conditions for Lemon Basil in the UK
To truly succeed ingrowing lemon basil in the UK, it's essential to provide the right conditions. Here's what lemon basil needs to thrive:
Sunlight
Lemon basil loves sunshine! Aim for at least 6-8 hours of direct sunlight per day. A south-facing location is ideal in the UK, as it provides the most sun exposure. If you're growing lemon basil indoors, place it near a sunny window or use grow lights to supplement natural light.
Soil
Well-draining soil is crucial for lemon basil. Heavy clay soil can lead to root rot, so it's important to amend it with organic matter like compost or well-rotted manure. A slightly acidic to neutral soil p H (around 6.0-7.0) is ideal. You can test your soil p H using a soil testing kit available at most garden centres.
Watering
Lemon basil needs consistent moisture, but avoid overwatering. Water when the top inch of soil feels dry to the touch. Water deeply, ensuring the water reaches the roots. Avoid splashing water on the leaves, as this can encourage fungal diseases. Consider using a soaker hose or drip irrigation system to deliver water directly to the soil.
Temperature
Lemon basil is sensitive to frost, so it's best to wait until all danger of frost has passed before planting it outdoors. Ideal growing temperatures are between 18-30°C (64-86°F). If temperatures drop unexpectedly, cover your plants with a frost cloth or bring them indoors.
Planting and Care Tips for Lemon Basil
Planting
When transplanting your lemon basil seedlings, space them about 12-18 inches apart. This allows them plenty of room to grow and prevents overcrowding. Dig a hole slightly larger than the root ball, gently remove the seedling from its pot, and place it in the hole. Backfill with soil and water thoroughly.
Fertilizing
Lemon basil benefits from regular feeding with a balanced liquid fertiliser. Feed every 2-3 weeks during the growing season. You can also use a slow-release fertiliser at planting time.
Pinching and Pruning
Pinching and pruning are essential for encouraging bushier growth and preventing your lemon basil from flowering prematurely. Pinch off the top set of leaves regularly to encourage side shoots to develop. Remove any flower buds as soon as you see them, as flowering will reduce leaf production and flavour.
Pest and Disease Control
Lemon basil is generally pest-resistant, but it can be susceptible to aphids, spider mites, and slugs. Inspect your plants regularly and take action if you notice any signs of infestation. Aphids can be washed off with a strong stream of water, while spider mites can be treated with insecticidal soap. Slugs can be controlled with slug pellets or by handpicking them off the plants.
Fungal diseases, such as powdery mildew and downy mildew, can also affect lemon basil, especially in humid conditions. To prevent these diseases, ensure good air circulation around your plants, avoid overwatering, and remove any infected leaves promptly. You can also use a fungicide if necessary.
Growing Lemon Basil in Containers
Lemon basil thrives in containers, making it ideal for small gardens, balconies, or patios. Choose a pot that is at least 12 inches in diameter and has good drainage holes. Use a well-draining potting mix and follow the same care tips as for growing lemon basil in the ground. Container-grown lemon basil may need more frequent watering and fertilising than plants grown in the ground.
Harvesting and Using Your Lemon Basil
Harvesting
You can start harvesting lemon basil leaves as soon as the plants are established. Simply snip off the leaves as needed. For best flavour, harvest in the morning, after the dew has dried. Regular harvesting encourages bushier growth and prevents the plant from flowering.
Using Lemon Basil
Lemon basil is a versatile herb that can be used in a variety of dishes. It's delicious in salads, pasta sauces, soups, and stir-fries. It also makes a refreshing tea. To preserve lemon basil, you can dry it, freeze it, or make pesto.

- Yellowing Leaves: Can be caused by overwatering, underwatering, nutrient deficiencies, or pests. Adjust watering practices, fertilise regularly, and inspect for pests.
- Leggy Growth: Often caused by insufficient sunlight. Move your plants to a sunnier location or provide supplemental light.
- Powdery Mildew: A white, powdery coating on the leaves. Improve air circulation, avoid overwatering, and use a fungicide if necessary.
- Downy Mildew: Yellowish spots on the upper surface of the leaves, with a greyish-purple mold on the underside. Remove infected leaves and improve air circulation.
