End of February to June
Where to Sow
Sowings can be made underglass, sow seeds into pots or trays of seed sowing compost at a temperature of 15-20C and lightly cover seeds with sprinkling of vermiculite or compost. Alternatively sow seeds from April thinly along rows 1.5cm (1/2in) deep and 30cm (12in) apart direct in the vegetable plot.
What to do next
Sowings made underglass can be pricked out into individual pots or module trays and grown on until ready to harden off and plant out into the vegetable plot 30cm (12in) apart between the plants and the rows. Seedlings sown direct outside can be thinned once large enough to handle to 30cm (12in) apart. Thinnings can also be transplanted into other rows, watered in well during hot dry spells.
10-12 weeks after sowing.
Regular watering around the roots and not on the foliage is essential, especially 7-10 days before maturity.
A good source of antioxidants such as beta-carotene, lutein and vitamin C as well as vitamin K.
