Basils in Bath

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 18–24 °C in a bright spot. Germination takes 7-14 days. Do this 16th February - 2nd March.

Once seedlings have their first true leaves, prick them out into individual 7–9 cm 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 16th March - 23rd March.

When roots fill the small pots, pot on into larger containers (e.g., 12–15 cm pots) to encourage strong growth before transplanting outdoors. Use a well-draining compost mix. This is done 30th March - 6th April.

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 6th April - 13th April.

Plant basil outdoors in a sunny, sheltered spot with well-drained soil after all risk of frost has passed. Space plants 25 cm apart. Water in well and consider using cloches or fleece if nights are cool. Transplant 13th April - 27th April.

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 20th November and continue until 4th May.

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 20th November onwards.

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 20th November until 4th June for continuous supply.
