King Choi Pak grows upright and compact, spacing just one inch apart in rows set 18 inches apart, which means you can pack surprising productivity into a small garden bed. The variety's frost tolerance and cool-season preference make it an excellent choice for shoulder-season harvests when many other crops have bolted or faded. Young plants do demand stable temperatures to avoid premature bolting, so timing and consistent moisture matter more here than with some other brassicas.
King Choi Pak is harvested fresh as a cool-season green vegetable. Individual leaves can be picked starting with the largest ones while the plant is still growing, or the entire head can be harvested once mature. The tender texture and mild flavor make it suitable for stir-frying, soups, and fresh preparations typical of pak choi in Asian cuisine.

Sow seeds 4 weeks before your anticipated transplant date for a spring crop. Seeds germinate between 55 and 70 degrees Fahrenheit.
Transplant seedlings outdoors after the danger of frost has passed in spring, or in July to August for fall crops. The variety's frost tolerance means fall plantings are particularly rewarding since they mature as temperatures cool.
For spring crops, direct sow seeds after the last frost date. Fall crops can be sown from July through mid-August for harvest before the first hard freeze.
Harvest as soon as the plant reaches maturity at 55 to 60 days to avoid bolting. You have two options: pick individual leaves starting with the largest, leaving smaller inner leaves to continue growing, or harvest the entire head once it reaches full size. Begin leaf harvesting when leaves are large enough to use but before the plant flowers.
