Sow and Plant
Sow bok choy in spring and again in late summer for harvest in fall. Sow in double rows, with rows spaced 10 inches (25 cm) apart. Plant seeds 2 inches (5 cm) apart and barely cover them with soil. Gradually thin to 8 inches (20 cm) apart. Miniature varieties can be grown 3 inches (8 cm) apart.
Also spelled pac choi, this lovely little mustard cousin is fast and easy to grow.
Pull whole plants for use in the kitchen.
Flea beetles often chew small holes in bok choy leaves in spring, but are less of a problem in the fall.
