Pak choi, also known as bok choy or Chinese cabbage, is a popular leafy vegetable that is commonly used in Asian cuisine. With its crisp texture and mild flavor, pak choi is a versatile vegetable that can be enjoyed in stir-fries, soups, salads, and more. If you’re interested in growing your own pak choi, this guide will provide you with detailed instructions on how to cultivate this nutritious and delicious vegetable in your garden or containers. From selecting the right variety to caring for your plants, we’ll cover all the essential steps to help you successfully grow pak choi.

Choosing the Right Variety:

When it comes to growing pak choi, there are several varieties to choose from. Each variety has its own unique characteristics and growth habits. Here are some popular pak choi varieties to consider:

Traditional Pak Choi:

Traditional pak choi, also known as standard or large pak choi, produces large, broad, and sturdy leaves. This variety is slower to bolt and is ideal for stir-frying and braising.

Baby Pak Choi:

Baby pak choi, also called Shanghai pak choi or dwarf pak choi, is harvested at a young age when the leaves are tender and small. It has a mild and delicate flavor, making it perfect for salads and quick cooking.


Tatsoi is a non-heading variety of pak choi that forms a rosette of dark green, spoon-shaped leaves. It has a slightly mustard-like flavor and is excellent for salads, stir-fries, and soups.

Shanghai Pak Choi:

Shanghai pak choi is a smaller variety that resembles a cross between baby pak choi and traditional pak choi. It has a mild taste and is versatile in cooking.

Preparing the Soil:

To ensure healthy growth and development of pak choi, it’s essential to prepare the soil properly. Here are the key steps to take:

Soil Type:

Pak choi prefers well-draining soil rich in organic matter. Sandy loam or loamy soil is ideal for pak choi cultivation. Avoid heavy clay soils that retain too much moisture, as this can lead to root rot.

Soil pH:

The optimal soil pH for pak choi is slightly acidic to neutral, ranging from 6.0 to 7.0. Conduct a soil test using a pH meter or a soil testing kit to determine the pH level of your soil. Adjust the pH if necessary by adding organic matter or soil amendments.

Soil Amendments:

If your soil lacks organic matter or nutrients, it’s beneficial to amend it before planting pak choi. Incorporate well-rotted compost, aged manure, or organic fertilizers into the soil to improve its fertility and structure.

Sowing Pak Choi Seeds:

Pak choi can be directly sown outdoors or started indoors and later transplanted. The following steps outline both methods of sowing pak choi seeds:

Indoor Sowing:

  • Fill seed trays or small pots with a seed starting mix.
  • Sow the seeds thinly, approximately ¼ inch deep.
  • Place the trays or pots in a warm location with ample sunlight or under grow lights.
  • Keep the soil consistently moist but not waterlogged.
  • After the seedlings have developed two to three true leaves, they are ready for transplantation.

Outdoor Sowing:

  • Prepare the soil by removing any weeds or debris and breaking up large clumps.
  • Sow the seeds thinly, approximately ½ inch apart, in rows or blocks.
  • Cover the seeds lightly with soil and gently firm it down.
  • Water the area gently to ensure good seed-to-soil contact.
  • Once the seedlings have emerged, thin them out to maintain proper spacing.

Seed Depth and Spacing:

When sowing pak choi seeds, the general rule of thumb is to plant them at a depth of approximately two times the diameter of the seed. Maintain a spacing of 6 to 12 inches between each plant, depending on the variety.

Transplanting Pak Choi Seedlings:

Transplanting pak choi seedlings allows for better control over growing conditions and spacing. Follow these steps to transplant your pak choi seedlings successfully:

Harden Off Seedlings:

Before transplanting, gradually acclimate the seedlings to outdoor conditions. Start by placing them in a sheltered area for a few hours a day, gradually increasing the time and exposure to direct sunlight over the course of a week.

Transplanting in the Garden:

  • Choose a location in your garden that receives full sun or partial shade.
  • Dig holes slightly larger than the root balls of the seedlings.
  • Gently remove the seedlings from their containers, taking care not to damage the roots.
  • Place each seedling in a hole and fill it with soil, ensuring the plants are at the same depth as they were in the containers.
  • Water the transplanted seedlings thoroughly.

Transplanting in Containers:

  • Select containers that are at least 6 to 8 inches deep and have drainage holes.
  • Fill the containers with a well-draining potting mix, leaving about an inch of space at the top.
  • Carefully remove the seedlings from their pots and place them in the containers.
  • Fill any gaps around the seedlings with additional potting mix, ensuring they are at the same depth as they were in their original containers.
  • Water the containers thoroughly, allowing excess water to drain.

Providing Optimal Growing Conditions:

To promote healthy growth and abundant harvest, it’s crucial to provide pak choi with the right growing conditions. Consider the following factors:


Pak choi thrives in full sun or partial shade. Ensure that your plants receive at least 4 to 6 hours of direct sunlight each day. In hot climates, partial shade during the hottest part of the day can help prevent bolting.


Keep the soil consistently moist but not waterlogged. Water your pak choi deeply and regularly, especially during dry periods. Avoid overhead watering, as wet foliage can increase the risk of diseases. Consider using drip irrigation or watering at the base of the plants.

Temperature and Humidity:

Pak choi prefers cool temperatures between 55°F and 75°F (13°C and 24°C). It can tolerate light frosts but may bolt when exposed to prolonged heat. Maintain proper air circulation to prevent excess humidity and minimize the risk of fungal diseases.

Fertilizing Pak Choi:

Proper fertilization is essential for the healthy growth and development of pak choi plants. Consider the following options for fertilizing your plants:

Organic Fertilizers:

Use well-rotted compost, aged manure, or organic fertilizers high in nitrogen, such as blood meal or fish emulsion. Apply them according to the manufacturer’s instructions or as recommended based on a soil test.

Synthetic Fertilizers:

If using synthetic fertilizers, choose a balanced or nitrogen-rich fertilizer. Follow the instructions on the fertilizer package and apply it at the recommended rate. Avoid over-fertilization, as it can lead to excessive leaf growth and reduced flavor.

Fertilizer Application Schedule:

Apply fertilizers to the soil before planting and continue to provide supplemental feedings throughout the growing season. For container-grown pak choi, fertilize every 4 to 6 weeks or as directed by the fertilizer label.

Controlling Pests and Diseases:

Like any other vegetable, pak choi is susceptible to pests and diseases. Here are some common issues and methods to control them:

Common Pests:

Common pests that can affect pak choi include aphids, flea beetles, cabbage worms, and slugs. Regularly inspect your plants for signs of infestation, such as chewed leaves or visible insects.

Natural Pest Control Methods:

Encourage beneficial insects like ladybugs and lacewings that feed on pests. Use physical barriers, such as row covers, to protect your plants from pests. If necessary, apply organic pest control methods, such as insecticidal soaps or neem oil.

Disease Prevention:

To prevent diseases, practice crop rotation and avoid planting pak choi or other brassica crops in the same location year after year. Ensure proper spacing between plants to promote good airflow and reduce the risk of fungal diseases. Remove and dispose of any infected plant debris.

Harvesting Pak Choi:

Pak choi can be harvested at different stages of growth, depending on your preference and the variety you’re growing. Follow these guidelines for harvesting pak choi:

Harvesting Baby Pak Choi:

Baby pak choi is typically ready to harvest within 30 to 45 days after sowing. Harvest it when the plants reach 4 to 6 inches in height. Cut the whole plant just above the soil line or pick individual outer leaves.

Harvesting Mature Pak Choi:

For mature pak choi, wait until the plants reach 8 to 12 inches in height. Cut the entire plant just above the soil line or remove outer leaves as needed.

Harvesting Tatsoi:

Tatsoi can be harvested as baby greens when the plants are 3 to 4 inches tall or as mature plants when they reach 8 to 10 inches in height. Cut the whole plant just above the soil line or pick individual leaves.

Storing and Using Pak Choi:

After harvesting, it’s essential to properly store and utilize your pak choi to preserve its freshness and flavor. Consider the following tips:

Storing Fresh Pak Choi:

Rinse the pak choi leaves thoroughly and pat them dry. Store them in a perforated plastic bag or airtight container in the refrigerator. Fresh pak choi can typically be stored for up to one week.

Freezing Pak Choi:

Blanch pak choi leaves in boiling water for 2 minutes, then transfer them to an ice bath to cool. Drain and pack the blanched leaves into freezer-safe bags or containers. Frozen pak choi can be stored for up to 8 to 12 months.

Cooking with Pak Choi:

Pak choi is a versatile vegetable that can be used in various dishes. Add it to stir-fries, soups, stews, salads, or even lightly steam or sauté it as a side dish. Experiment with different recipes and cooking methods to enjoy the flavors and textures of pak choi.
