WHEN TO SOW
May to August
Where to Sow
Outdoors: sow thinly where they are to crop, 1.5cm (½") deep, directly into finely-prepared soil. Sow from May for baby leaf, June onwards for full-size plants. Allow 40cm (16in) between rows. Can also be sown into modules filled with seed sowing compost and transplanted out , filling vacant spaces on the plot.
What to do next
Keep well watered in dry spells. Harvest unthinned as baby leaves, can also thin out seedlings or plant out modules to 25cm (10in) apart to produce mature plants. Regular sowings, made every two to three weeks, will ensure a continuous supply.
For 'baby leaf', pick a few leaves from each plant when 5cm (2") tall, then allow to regrow for up to four pickings.
