Swede - Best of All This variety is very hardy and easy to grow, with rich yellow flesh, smooth texture and mild flavour. Sow outdoors thinly from May to July, where they are to crop, 1.5cm deep, directly into finely-prepared, rich, well-dug soil, which has already been watered. Allow 45cm between rows. Seedlings usually appear in 14-21 days. Thin out to 25cm apart. Water well until plants are established. Make two or three successional sowings to provide a crop throughout the winter. Harvest from October to March.
