Spring Onion - North Holland Blood Red This is an attractive and versatile variety with mild flavour and crisp flesh. Use young as salad onions or grow on as bulbing onions. The colour intensifies with maturity. Sow outdoors thinly, from February to July, where they are to crop, 1.5cm deep, directly into finely-prepared, well-dug, fertile soil, which has already been watered. Allow 15cm between rows. Early and late sowings may benefit from cloche protection. Seedlings usually appear in 14-21 days. For spring onions, no thinning is required, but keep well-watered in dry spells. Regular sowings, made every two to three weeks, will ensure a continuous supply through the summer. Harvest from April to October. For bulb onions, sow no later than April. Thin seedlings to 8cm apart. Harvest from July onwards.
