Basil Plants FAQs
Take a look at some of the frequently asked questions we receive from those looking to buy Basil Plants in the UK. You can contact our Customer Service Team or browse our general FAQs for further advice.
When to plant Basil Plants
Basil plants should be sown indoors from March to May and transplanted outdoors once the risk of frost has passed, typically in late May or early June. They require warm temperatures of at least 15°C to thrive. Basil can also be grown year-round indoors on a sunny windowsill.
How to Plant Basil Plants
Basil thrives in well-drained, fertile soil in a warm, sunny position. Sow seeds in pots or directly into garden beds, spacing plants about 20–30cm apart. If growing in containers, ensure they have good drainage to prevent root rot. Regularly pinch out the growing tips to encourage bushy growth and prevent flowering, which can reduce leaf flavour.
How long do Basil Plants take to grow?
Basil plants typically take 4–6 weeks to reach a harvestable size from seed. Once established, they will continue producing fresh leaves throughout the summer if regularly harvested. Pinching off flowers helps extend the growing season and ensures a continuous supply of aromatic leaves.
Why should I plant Basil Plants?
Growing your own basil ensures a fresh, flavourful supply of this aromatic herb for cooking. Basil is a key ingredient in Mediterranean and Asian dishes, making it perfect for homemade pesto, pasta, salads, and soups. It also has natural antibacterial properties and is rich in vitamins A and K. Plus, basil attracts pollinators to the garden, benefiting other plants.
Where can I plant Basil Plants?
Basil grows best in warm, sheltered outdoor beds, containers, or indoors on a sunny windowsill. It thrives in greenhouses and polytunnels, where temperatures remain consistently warm. If planting outdoors, choose a location with full sun and well-drained soil, or grow in pots that can be moved inside during cooler weather.
