Select an area of your garden that gets part shade if possible. Bok Choy likes 3 to 5 hours of sunlight each day for the best growth.

Before planting add 1-2 inches (2.54-5.08 cm) of compost to your garden.

Start bok choy by seed indoors 4 to 5 weeks before your last frost date. Plant seeds 1/4 inch (6.35 mm) deep in cell packs and keep them in a bright window or under lights. Until nighttime temperatures stay above 50 F (10 C) then you can harden off the seedlings and transplant them into your garden.

To direct seed in the garden wait until 1-2 weeks before your last frost date. Then plant seeds 1/4 inch (6.35 mm) deep and 1 inch (2.54 cm) apart.

Keep the soil moist and provide 1 inch (2.54 cm) of water each week. Mulch to help suppress weeds and reduce watering.

Once the seedlings have grown about 2-3 inches tall thin the plants to be 6 inches  (15.24 cm) apart for full-sized plants. If you are growing them for baby leaves the plants can be grown closer.

Start harvesting the outer leaves when the plants are 3 weeks old. For a full-sized head wait to harvest until 45-60 days according to your seed package, then cut off at soil level.
