White Onions - These onions tend to have a sharper & more pungent flavor than yellow onions. They also tend to be more tender & have a thinner, more papery skin. They can be cooked just like yellow onions, but we also like them minced & added to raw salsas & chutneys. SOWING Harvesting: August - September Sow in March - April Sow very thinly in 1 cm ( inch) deep drills, leaving about 25 to 30 cm (10 to 12 inches) between rows. When large enough to handle, thin the crop in two stages. Close spacing will give smaller onions than wider spacings. Lift the seedlings carefully - the soil should be moist & all thinnings removed to deter onion fly. (They may be used as spring onions) Thin Spring-sown seedlings first to 2.5cm (1 inch) then when the seedlings have straightened up to 5 to 10 cm (2 to 4 inches) apart. Thin Autumn sown onion seedlings to about 2.5cm (1 inch) in the autumn. Further thin to about 5 to 10 cm (2 to 4 inches) between plants in the Spring.
