Choosing the Right Plants or Seeds

When it comes to growing bok choy, you have two options: starting with seeds or buying young plants.

When buying young plants, make sure to select plants that look healthy and have a good root system. Avoid plants that look wilted or have yellowing leaves.

Grow Bok Choy from Seed


Starting Seeds Indoors

Starting bok choy seeds is an easy and cost-effective way to grow this tasty green in your garden. To get started, sow seeds indoors 4-6 weeks before the last frost date in your area. Fill your seed trays with a good quality seed starting mix. Drop about 2 or 3 seeds in each cell, then cover lightly with more mix.

Water the seeds gently and use a humidity dome to keep the soil moist. Bok choy seeds should germinate in 7-14 days. If you don’t have an area that receives at least 8 hours of direct sunlight then you’ll need to use a seedling grow light. Once the seedlings have their first true leaves, thin them out so that there is only one seedling per cell.

Before transplanting into the garden, be sure and harden off the seedlings by gradually acclimate them to full sun and outdoor conditions. This can be done by placing them outside in a sheltered area for a few hours each day.

When transplanting into the garden, dig a hole for each plant, and plant them so that the base of the stem is level with the soil surface. Water the plants well and keep the soil moist until they are established.

Direct Sowing Seeds Outdoors

Sow the seeds thinly, about ¼ inch deep and 2-3 inches apart. Cover the seeds with soil and water gently but thoroughly. Keep the soil moist until the seeds germinate, which should take around 7-14 days. Thin the seedlings so that each plant is spaced about 6-8 inches apart.

As the seedlings grow, keep the soil moist and fertilize every two weeks with a balanced fertilizer. Mulching around the plants can help to retain moisture in the soil and suppress weeds.

When to Plant Bok Choy

The exact month to plant bok choy can vary depending on your location and climate. In general, bok choy can be planted in early spring, after the last frost date. For a fall harvest, sow seeds about 8-10 weeks before the first expected frost.

Selecting the Right Location


Bok choy grows best in cool temperatures and partial shade. When selecting a location to grow your bok choy, look for a spot that gets morning sun and afternoon shade. If you live in a hot climate, consider growing your bok choy in a location that gets full shade.

In hot weather bok choy can bolt, or go to seed prematurely, . To avoid this, try to plant your bok choy in the early spring or fall, or in a location that receives partial shade during the hottest part of the day.

Ideal Soil to Grow Bok Choy

Bok choy prefers well-draining soil with a pH between 6.0 and 7.5 that is rich in organic matter. Before planting, amend your soil with compost or well-rotted manure. Make sure to work the organic matter into the soil to a depth of at least 6 inches.

Watering Needs

Bok choy requires consistent moisture to thrive. Water your plants deeply once a week, making sure to soak the soil to a depth of at least 6 inches. During periods of extreme heat or drought, you may need to water your plants more frequently.

Additionally, providing consistent moisture and avoiding letting the soil dry out completely can help to prevent bolting.

Type of Fertilizer

Bok choy requires regular fertilization. Use a balanced water soluble fertilizer, such as a 10-10-10 or 20-20-20 formula, every 2-3 weeks during the growing season. Make sure to follow the manufacturer’s instructions for application

Harvesting Bok Choy

Bok choy is typically ready for harvest about 45-60 days after germination. You can either harvest the entire plant or just the outer leaves, leaving the inner leaves to continue growing. Use a knife to remove outer leaves to prevent tearing.

To harvest the entire plant, use a sharp knife or pair of scissors to cut the stem just above the soil line. Be sure to harvest before the plant starts to flower, as the leaves will become bitter at this point.

Pests and Diseases

Like most vegetables, bok choy is susceptible to pests and diseases.
