Basil

Basils in Albert Town

Ocimum basilicum

Basil is a fragrant, tender herb whose leaves are a staple of summer cooking. Native to tropical regions, basil is treated as an annual in temperate climates like the UK because it cannot tolerate frost. It thrives in warm, sunny conditions and can be grown in garden beds or pots for a steady supply of fresh, flavourful leaves throughout the summer.

Step-by-step guide to growing basil by starting seeds indoors and transplanting outside after the last frost.

1
Sow Seeds Indoors

25 Jan - 8 Feb

Sow basil seeds thinly on the surface of moist seed compost in trays or pots. Cover lightly with vermiculite or a fine layer of compost, as they need some light to germinate. Keep at in a bright spot. Germination takes 7-14 days. Do this 25th January - 8th February.

2
Prick Out Seedlings

22 Feb - 1 Mar

Once seedlings have their first true leaves, prick them out into individual pots filled with multi-purpose compost. Handle gently by the leaves to avoid stem damage. Keep in a warm, bright location. This step occurs around 22nd February - 1st March.

3
Pot On Seedlings

8 Mar - 15 Mar

When roots fill the small pots, pot on into larger containers (e.g., pots) to encourage strong growth before transplanting outdoors. Use a well-draining compost mix. This is done 8th March - 15th March.

4
Harden Off Plants

15 Mar - 22 Mar

Gradually acclimate plants to outdoor conditions over 7-10 days before transplanting. Start by placing them outside in a sheltered spot for a few hours each day, increasing exposure. Protect from strong winds and cold nights. Harden off 15th March - 22nd March.

5
Transplant Outdoors

22 Mar - 5 Apr

Plant basil outdoors in a sunny, sheltered spot with well-drained soil after all risk of frost has passed. Space plants apart. Water in well and consider using cloches or fleece if nights are cool. Transplant 22nd March - 5th April.

6
Water and Feed Plants

26 Nov - 12 Apr
every 2 weeks

Water basil regularly to keep the soil consistently moist but not waterlogged. Feed every 2-3 weeks with a balanced liquid fertiliser to support leafy growth. Start feeding from 26th November and continue until 12th April.

7
Pinch Out and Prune

26 Nov - 19 Apr

Regularly pinch out the growing tips and any flower buds to encourage bushy growth and prevent bolting. Harvest leaves from the top down, taking no more than one-third of the plant at a time. Do this from 26th November onwards.

8
Harvest Leaves

26 Nov - 13 May

Harvest basil leaves regularly once plants are well-established. Pick in the morning for the best flavour, using scissors or pinching off stems above a leaf pair. Harvest from 26th November until 13th May for continuous supply.

Companion Plants

Why Companion Planting Matters

Companion planting can help deter pests, improve pollination, enhance growth, and maximize garden space. Some plants release chemicals that repel pests or attract beneficial insects, while others can improve soil quality or provide shade for sensitive plants.

Suggested Varieties

Popular varieties of Basil to consider

Sweet Basil

The classic variety with large, aromatic green leaves, ideal for pesto and Italian dishes.

Greek Basil

A compact, bushy variety with small leaves, perfect for container growing and slower to bolt.
