What is lemon basil, what is it good for and how do you grow it at home?
Lemon basil (Ocimum basilicum var. citriodorum) is an aromatic variety of basil known for its unique citrus scent and flavour. It is often used in cooking and natural medicine, and is especially prized in Asian and Mediterranean dishes.
As well as enriching dishes with its refreshing aroma, it is rich in vitamins A and C, minerals such as calcium, iron and magnesium, and antioxidant compounds that support immunity and digestion.

Growing lemon basil at home
Lemon basil can be grown in the garden, on the balcony or indoors. For optimal growth it needs 12–16 h of light per day, a well-aerated substrate and regular but moderate watering. Indoors, LED lighting placed 20–30 cm above the plant is recommended.
Planting lemon basil from seed
- Choose a pot with drainage holes or a smart planter.
- Use a light, well-draining substrate or our smart soil with nutrients.
- Sow the seeds shallowly and cover lightly with a thin layer of soil.
- Keep it moist, but avoid standing water.
- Provide 12–16 h of light per day.

How to pick lemon basil so it keeps growing
- Pick the stem tips above the second pair of leaves.
- Regularly pinch off the top leaves to encourage new growth.
- It is best picked in the morning, when the concentration of essential oils is highest.
Common problems and solutions
| Problem | Possible cause | Solution |
| Yellow leaves | Too little light, too much water | Move to a brighter spot, adjust the watering |
| Weak scent/citrus | Too little light | Extend the lighting time (LED 12–16 h) |
| Weak growth | Overcrowded planting, nutrient deficiency | Thin the plants, add organic fertiliser |
| Pests | Whiteflies, aphids | Remove by hand, use natural repellents |
| Mould | Too much moisture, poor ventilation | Improve air circulation and water moderately |
The difference between lemon basil and regular basil
- Lemon basil (Ocimum basilicum var. citriodorum): has a distinctive citrus aroma and is used in teas, marinades, desserts and Asian dishes.
- Genovese basil (Ocimum basilicum): the classic Italian basil, ideal for pesto, sauces and salads.
How to store lemon basil
- Fresh leaves in water – keep the stems in a glass of water at room temperature.
- Freezing – freeze the leaves whole or chopped in olive oil.
- Drying – dry in the shade and store in airtight containers.
- Basil oil – steep the leaves in olive oil for flavouring.
- Do not keep in the fridge below 10 °C – it loses its aroma and darkens.
