Pak Choi - Colour and Crunch F1 This is a great tasting and colourful mixture of tasty leaves and crunchy stems with many uses, from salads to stir fries or wilted into rice or noodle dishes. Wonderfully easy to grow in beds or containers, with little or no waste. Sow outdoors thinly, from May to August where they are to crop, 1.5cm deep, directly into finely-prepared, well-dug, fertile soil, which has already been watered. Sow from May for baby leaf, June onwards for full-size plants. Allow 40cm between rows. Seedlings usually appear in 14-21 days. Keep well-watered in dry spells. Harvest unthinned as baby leaves, or thin to 25cm apart to produce mature plants. Regular sowings, made every two to three weeks, will ensure a continuous supply. Harvest from July to October. For 'baby leaf,' pick a few leaves from each plant from approx. 5cm high. They will regrow for up to 4 'cuts.'
