Basil Lemon

What Basil Lemon is

Basil Lemon (Ocimum basilicum) is an annual herb of the Mint family (Lamiaceae). Basil Lemon is a strongly upright plant with grey-green leaves and numerous stems.

Lemon basil is considered an annual, but its life can be extended if it is brought indoors when the weather cools.

As a culinary herb, lemon basil produces both leaves and seeds, and so should be encouraged to flower for seed collection.

The seeds have a strong lemon aroma and can be soaked in water to make a lemon tonic. As a plant it has a reputation for needing care and attention, but it is worth the effort.

Basil is the king of aromatic herbs — for tomato salad, pesto, pasta and pizza. It grows easily in the garden, in a pot and on a windowsill.

How to sow and grow Basil Lemon

• Depth: 0.3–0.5 cm
• Spacing: 20–30 cm
• Germination: 5–10 days at 20–25 °C
• Position: sunny spot

Basil seeds need warmth to germinate, ideally around 21°C. This can easily be achieved on a sunny windowsill indoors. Basil can also be grown indoors all year round, especially if you have a sunny window or full-spectrum lights. It does great in containers; just make sure you add some compost or another nutrient-rich amendment to your potting mix. Once germinated, encourage strong seedlings by giving them plenty of sun and moisture. Do not overwater: basil seedlings are very prone to damping off. A greenhouse is the ideal place for your basil plants, just make sure you water them often to prevent them from flowering prematurely.

Sow in warm soil — below 12 °C basil stops growing. Pinch out the tips so it branches, and remove flowers for more leaves.

Harvest and use

Pick the leaves before flowering — the aroma is strongest then. Cut above a pair of leaves so that new shoots form.
