Sow: From end of March to April, then every 3 to 4 weeks. May not germinate if temperature below 7 degrees C. Pre-soaking seed for 24 hours may help germination. Sow direct in soil or in pots, in clusters.
Aspect: Greedy feeder.
Water: regularly to prevent soil drying out, which will cause plants to bolt. Over-watering will encourage leaf production instead of root growth.
Harvest: Use thinnings as salad leaves. When large enough to use - golf-ball sized ones have better flavour. Twist off foliage to avoid 'bleeding'.
Don't grow by: Beans
