Pak choi is a member of the brassica family, which also includes broccoli, kale, and cauliflower. It has dark green leaves and white stalks, and is commonly used in stir-fries, soups, and salads.

Growing pak choi is relatively easy and can be done in a variety of settings, including in containers on a balcony or in a backyard garden. It prefers cooler temperatures and partial shade, making it an excellent choice for spring and fall planting.

In this article, we will explore the basics of growing, maintaining, and harvesting this versatile vegetable, including tips on soil preparation, watering, and pest control. Whether you’re an experienced gardener or a beginner, you can enjoy the fresh taste and nutritional benefits of homegrown pak choi.

Selecting the Right Site for Growing Pak Choi

When it comes to growing pak choi, choosing the right location is crucial for the success of your crop. Pak choi thrives in cooler temperatures and requires plenty of sunlight and well-drained soil. It can grow in both partial shade and full sun, but it will do best with at least six hours of direct sunlight per day.

When selecting a site for your pak choi, look for an area that is sheltered from strong winds, which can damage the delicate leaves. The soil should be rich in organic matter and have a pH level of around 6.0 to 7.0. To ensure good drainage, consider planting pak choi in raised beds or mounds.

It’s also important to avoid planting in areas that have recently grown members of the brassica family, such as cabbage or broccoli, as these plants can attract similar pests and diseases. Instead, opt for a new area or rotate your crops to prevent the buildup of soil-borne diseases.

By choosing the right site for pak choi, you can ensure that your crop will grow healthy and strong, providing you with a bountiful harvest of delicious and nutritious greens.

Preparing Soil for Pak Choi

One of the most important aspects of growing healthy and productive pak choi is preparing the right soil. Pak choi prefers well-draining soil that is rich in organic matter and has a pH between 6.0 and 7.0. To prepare the soil, begin by removing any weeds or debris from the planting area. Loosen the soil to a depth of at least 12 inches (30 cm) with a garden fork or tiller, being careful not to disturb the roots of any nearby plants.

Next, mix in compost or well-rotted manure to add nutrients and improve soil structure. The recommended amount is 2 to 3 inches (5 to 8 cm) of compost or manure per 100 square feet (9 square meters) of planting area. Work the compost or manure into the top 6 to 8 inches (15 to 20 cm) of soil.

If the soil is clayey or heavy, add some sand or perlite to improve drainage. A good rule of thumb is to add 1 to 2 inches (2.5 to 5 cm) of sand or perlite per 100 square feet (9 square meters) of planting area. Mix it thoroughly into the soil to ensure even distribution.

Before planting pak choi, it’s a good idea to perform a soil test to check for nutrient deficiencies and pH levels. You can purchase a soil test kit at a local garden center or send a soil sample to a lab for analysis. Based on the results, you may need to add lime to raise the pH or sulfur to lower it. You may also need to add additional nutrients such as nitrogen, phosphorus, and potassium based on the soil test results.

Taking the time to prepare the soil properly will ensure that your pak choi grows strong and healthy, producing a bountiful harvest.

Sowing and Planting Pak Choi

Sowing and planting Pak Choi is a relatively easy process that can be done either in pots or directly in the ground. To start, it’s important to choose a location that receives at least six hours of sunlight per day. Pak Choi prefers well-drained soil with a pH between 6.0 and 7.5. If the soil is not ideal, you can amend it with compost, manure or other organic matter to improve its texture and fertility.

When sowing Pak Choi, it’s important to space the seeds at least 2 inches (5 cm) apart to allow the plants to grow properly. You can either sow the seeds directly in the ground or start them indoors in pots. If starting them indoors, plant the seeds about 4 to 6 weeks before the last frost date in your area. This will give them enough time to germinate and grow before transplanting them outside.

Once the Pak Choi seedlings have grown to around 4 to 6 inches (10 to 15 cm) tall, they can be transplanted outside. If planting in the ground, dig a hole slightly larger than the pot the seedling is in and place it in the hole. Be sure to cover the roots completely with soil and gently press the soil down around the plant to remove any air pockets. If planting in a pot, fill the pot with well-drained soil and gently remove the seedling from its original container. Place it in the pot and cover the roots with soil.

It’s important to water the Pak Choi regularly, especially during hot and dry weather. However, be careful not to overwater as this can lead to root rot. A good rule of thumb is to water when the soil feels dry to the touch. Fertilizing with a balanced fertilizer every two to three weeks can also help promote healthy growth and yields.

In summary, sowing and planting Pak Choi is a simple process that requires a bit of attention and care. By choosing the right location, amending the soil if necessary, spacing the seeds properly, and providing adequate water and fertilizer, you can enjoy a bountiful harvest of this nutritious vegetable.

Watering and Fertilizing Pak Choi

Watering and fertilizing are essential parts of growing pak choi successfully. In this chapter, we will discuss how to water and fertilize your pak choi to ensure it grows healthy and strong.


Pak choi needs consistent moisture to thrive, so it’s important to water it regularly. A good rule of thumb is to water your pak choi deeply once or twice a week, depending on your climate and soil conditions. You want the water to penetrate at least 6 inches (15 cm) into the soil to ensure the roots are getting enough moisture.

It’s also important to water your pak choi in the morning or early afternoon to avoid wetting the leaves during cooler evening temperatures. Wet leaves can increase the risk of fungal diseases, so it’s best to avoid watering late in the day.


Pak choi is a heavy feeder, meaning it requires a lot of nutrients to grow properly. Before planting, it’s recommended to amend your soil with compost or well-rotted manure to provide a good base of nutrients.

Once your pak choi is established, you can begin fertilizing it. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium is a good choice for pak choi. Apply the fertilizer according to the manufacturer’s instructions, and be sure not to over-fertilize, as this can damage the plant.

To give your pak choi an extra boost, you can also feed it with a foliar fertilizer. This is a liquid fertilizer that you spray directly on the leaves of the plant. Foliar feeding can be done once a week in the morning or early afternoon.

By watering and fertilizing your pak choi correctly, you can ensure it grows strong and healthy, producing delicious and nutritious leaves for your meals.

Companion Plantin with Pak Choi

Companion planting is a gardening technique where plants with mutually beneficial qualities are grown in close proximity to each other. Companion planting with Pak Choi can help improve the health and yield of your plants.

One of the best companion plants for Pak Choi is lettuce. Lettuce provides a natural shade for the Pak Choi, protecting it from the hot sun during the day. This can help prevent the Pak Choi from bolting, or going to seed, too quickly.

Another great companion plant for Pak Choi is garlic. Garlic is a natural pest repellent, helping to keep aphids and other pests away from your Pak Choi plants.

Carrots and radishes are also good companion plants for Pak Choi. These root vegetables help break up the soil, allowing for better drainage and aeration. Additionally, the spicy oils in radishes can help repel pests.

Avoid planting Pak Choi near plants from the brassica family, such as broccoli or cauliflower, as they can attract similar pests and diseases.

When selecting companion plants for Pak Choi, make sure to choose plants that have similar watering and fertilization needs. By planting complementary plants, you can create a diverse and healthy garden ecosystem.

Managing Pests and Diseases in Pak Choi

Pak choi is generally a hardy and low-maintenance plant, but it can still be susceptible to certain pests and diseases. Here are some common issues that you may encounter when growing pak choi and how to manage them.


  • Aphids: These small, pear-shaped insects can suck the sap from your pak choi plants and cause yellowing and distortion of the leaves. You can spray them off with a strong jet of water or use an insecticidal soap or oil to control them.
  • Flea beetles: These small, black beetles can chew small holes in the leaves of your pak choi. You can use row covers to prevent them from laying eggs on your plants or spray with neem oil.

Harvesting and Storing Pak Choi

Pak Choi is usually ready for harvest around 45-60 days after sowing. The plants are usually harvested when they reach 6-8 inches (15-20 cm) tall. However, if you prefer larger leaves, you can wait a bit longer. It’s best to harvest Pak Choi early in the morning when the plants are turgid and the temperatures are cool.

To harvest Pak Choi, use a sharp knife or scissors to cut the stem at the base of the plant. Avoid pulling or twisting the plant, as this can damage the roots of nearby plants.

After harvesting, wash the leaves thoroughly in cold water to remove any dirt or debris. If you’re not using the Pak Choi immediately, store it in the refrigerator. Pak Choi can be stored in a plastic bag for up to a week.

If you want to store Pak Choi for a longer period of time, you can blanch and freeze it. To blanch Pak Choi, submerge the leaves in boiling water for 1-2 minutes, then immediately place them in a bowl of ice water to cool. Once cooled, drain the leaves and pack them into freezer bags. Frozen Pak Choi can be stored for up to 8 months.

By following these simple steps, you can enjoy fresh, delicious Pak Choi throughout the growing season and beyond.
