How to Grow Napa Cabbage: Tips for Successful Cultivation and Harvesting
How to Grow Napa Cabbage?
To grow Napa cabbage, start by planting seeds indoors six weeks before the last frost for midsummer harvesting.
Alternatively, plant in midsummer for a fall harvest.
Choose a planting site with well-draining soil and partial sun.
Napa cabbage can grow in full sun or partial shade but needs 4-5 hours of direct sun daily.
The soil should be organically rich, loamy or sandy, with good drainage and a slightly acidic to neutral pH.
Water the plants when the soil feels dry about an inch or two down, as regular watering is important for growth and to prevent early seeding.
Good air circulation is important to prevent rot and fungal diseases.
You can expect heads to be ready for harvest 70-90 days after seedlings sprout.
To harvest, wait until the head feels firm and dense.
Cut the head at its base or pull up the entire plant.
Napa cabbage can be stored in the refrigerator for up to two weeks and can be used in various recipes calling for regular cabbage or bok choy.

Introduction To Napa Cabbage
Napa cabbage, also known as Chinese cabbage, Peking cabbage, or celery cabbage, is a biennial vegetable belonging to the Brassicaceae family. Its botanical name is Brassica rapa Pekinensis.
Native to Asia, Napa cabbage is a popular vegetable known for its mild and sweet flavor. It is larger than bok choy, another popular Asian vegetable, and has delicate, crinkled, pale green to white leaves with crisp, wide white ribs.
Napa cabbage is commonly used in various cuisines and can be cooked or eaten raw in salads. In this article, we will explore the process of growing Napa cabbage, including:
- Planting and care
- Harvesting
- Storage
- Growing in containers
- Dealing with pests and diseases
- Recommended varieties
Note: Napa cabbage is a versatile and tasty vegetable that can enhance the flavor of many dishes. Follow the steps below to grow it successfully.
Growing Napa Cabbage: Planting And Care
To grow Napa cabbage, follow these steps:
- Select a planting site: Choose an area with well-draining soil and partial sun. The soil should be organically rich, loamy or sandy, and have sharp drainage with a slightly acidic to neutral pH.
- Ideal soil temperature: Napa cabbage can tolerate both warm and cool weather, but the best soil temperature for growth is between 60 and 65 degrees Fahrenheit.
- Sunlight requirements: The plants need 4-5 hours of direct sun daily.
- Prepare the soil: Before planting, mix compost into the soil to enrich it and provide necessary nutrients for the plant’s growth.
- Planting time: You can start Napa cabbage seeds indoors six weeks before the last frost for midsummer harvesting. Alternatively, in most regions, it is more common to plant Napa cabbage in midsummer for fall harvest.
- Planting depth: Plant the seeds around 1/4 inch deep, with a spacing of every 6 inches. Thin out the seedlings once they reach 5 inches in height.
- Watering: Regular watering is important to promote growth and prevent early seeding. Water the plants when the soil feels dry about an inch or two down.
- Air circulation: Good air circulation is essential to prevent rot and fungal diseases, so avoid overcrowding the plants.
- Support structures: While Napa cabbage doesn’t require support structures, you can use stakes or trellises if desired.
- Fertilizing: Use a balanced fertilizer on young plants during the early stages of growth. However, stop fertilizing once the heads start to develop to avoid splitting.
- Pollination: Bees and other pollinators can assist with pollination, but their presence is not necessary unless you want the cabbage to go to seed.
Remember to follow these steps for successful Napa cabbage growth.
Harvesting And Storage Of Napa Cabbage
Napa cabbage heads are generally ready to harvest 70-90 days after the seedlings sprout. Harvesting can be done by cutting the head at its base or by pulling up the entire plant. The heads should feel firm and dense when touched. If a head splits, it is important to harvest it as quickly as possible to prevent disease and pests.
Once harvested, Napa cabbage can be stored in the refrigerator for up to two weeks. To maximize shelf life, it is recommended to wrap the cabbage in plastic wrap or place it in a perforated plastic bag to retain moisture. Avoid washing the cabbage before storing as excessive moisture can lead to spoilage.
Napa cabbage is versatile and can be used in various recipes. It can be substituted for regular cabbage or bok choy in dishes and is often used as wrappers for steaming or blanching. Its mild flavor complements a wide range of ingredients.
Tips For Growing Napa Cabbage In Containers
To successfully grow Napa cabbage in containers, follow these steps:
- Select a container with a minimum size of 5 gallons per plant. This ensures enough space for the roots to grow.
- Use a well-draining, all-purpose potting mix or a mix specifically made for vegetable growth. This provides the necessary nutrients for the plants.
- Make sure the container has sufficient drainage holes to prevent waterlogging. Excess water can lead to root rot.
- It is preferable to start with seedlings when planting in a container rather than repotting. Repotting can stress the plant and affect its growth.
- Place the container in a location with partial sun. Napa cabbage requires sunlight for optimal growth.
- Follow the same planting and care instructions as for in-ground cultivation. This includes proper spacing between plants and regular fertilization.
- Regular watering is vital for container-grown plants, as they tend to dry out more quickly than those planted in the ground. Monitor the soil moisture and water as needed to prevent drying out.
By following these guidelines, you can successfully grow Napa cabbage in containers. Ensure that the plants receive proper care, including sufficient sunlight and regular watering, to promote healthy growth.
Common Pests And Diseases Of Napa Cabbage
Napa cabbage is susceptible to various pests and diseases that can affect its growth and yield. Common pests include clubroot, cabbage yellows, black rot, blackleg, cabbage worms, cabbage loopers, and flea beetles. To prevent these issues, it is important to practice good garden hygiene.
Avoid planting Napa cabbage in soil that previously hosted other Brassica species, as pathogens that affect the genus can persist in the soil. Regularly inspect the plants for any signs of pests or diseases. If an infestation occurs, various organic or chemical control methods can be employed, depending on the severity.
For example, introducing beneficial insects, such as ladybugs or parasitic wasps, can help control cabbage worm populations. It is also important to remove any damaged or drooping leaves to prevent the spread of diseases.

Frequently Asked Questions
How long does napa cabbage take to grow?
The growth of Napa cabbage depends on the method of planting. When starting from seeds, it typically takes around 70 to 90 days for Napa cabbage to be ready for harvest. However, if transplants are used instead, the growth time can be slightly shorter, ranging from 60 to 70 days. It is important to determine the optimal harvest time by feeling the firmness of the heads before picking them.
Does napa cabbage like sun or shade?
Napa cabbage thrives best when planted in moist, fertile soil with good drainage and exposed to either full sun or partial shade. It is important to note that previous years’ brassica crops should be avoided when selecting a planting location. Giving each plant sufficient space, approximately 3 feet, allows for optimal growth. Whether it is planted in a row of crops, a raised bed vegetable garden, or incorporated into an island bed or border, napa cabbage will flourish in these conditions.
What season is napa cabbage?
Napa cabbage is a cool-season vegetable, thriving during autumn through late winter. With its origins in the Mediterranean region, this versatile cabbage variety made its way to Japan through China in the late 1800s. Known as Chinese cabbage or hakusai in Japanese, it is highly sought after during its season, offering a crisp and refreshing addition to various dishes.
How to grow Chinese cabbage?
To grow Chinese cabbage, start by selecting an open sunny site with deep and rich soil. It is recommended to add well-rotted manure or garden compost to the soil, as it helps retain moisture. Weeding thoroughly before planting is crucial. While Chinese cabbages prefer full sun, providing partial shade in the summer can help prevent them from bolting. With the right soil preparation and proper care, you can enjoy a bountiful harvest of this delicious vegetable.
