Mix a light application of a balanced organic fertiliser into the soil prior to planting.
Seed should be sown at a depth of 15 to 20 mm (0.6–0.7 in) in soil with a pH between 5.5 and 7.0 and plant should be spaced approximately 20 cm (8 in) from one another.
Transplants can be taken from a 4–5 week old plant if a spring crop is desired.
The plants can be grown on flat or raised beds and positioned in rows 50–60 cm (20–24 in) apart.
Each plant should be spaced 50 cm (20 in) from its neighbor for optimum growth.
Bok choy is most successfully grown in regions that experience cool summers and mild winters, growing optimally in temperatures between 15 and 20°C (59–68°F).
Bok choy can be planted in early spring if the required climatic conditions are met, producing a crop in early summer or they can be planted in early summer for a late summer crop.
The seeds will germinate quickly and seedlings are fast growing.
Transplants may also be used.
Choose a pot 50cm deep and wide, To further discourage bolting when growing bok choy as a spring crop, try planting bok choy in partial shade and keep it well-watered.
Fill with potting mix, and plant bok choi seeds 10cm apart, space the rows 50cm apart.
