What to do through the growing season
01
Sow seeds into individual modules around 23rd March - 6th April. Cover with of compost and keep the compost just moist while seedlings emerge.
02
When seedlings have a couple of true leaves, from 6th April to 4th May, move them into individual pots if their modules are crowded. Handle them by the leaves, not the stems, and keep them in bright light so they do not become leggy.
03
From 20th April to 11th May, move plants outside for longer each day before planting them out. Protect them from cold nights and strong wind, and keep them in a sheltered spot at first.
04
Once the soil has warmed and frost risk has passed, plant out your hardened-off seedlings around 4th May - 18th May. Space them apart, water in thoroughly straight after planting, and give them a sunny spot with free-draining soil.
05
From 3rd June to 7th November, remove fading flowers regularly so the plant keeps producing new blooms instead of setting seed. Water only in dry spells, because rich soil and heavy feeding usually mean more leaves and fewer flowers.
06
Pick flowers and young leaves from 3rd June until 7th November. Harvest in the morning for the best flavour, and take only a few leaves from each plant so it keeps flowering well.
