Nutrition & Health Benefits
Also Known As: Canton's Choice, Bok Choi.
Native Range: Europe
Ease of Growing: Moderate
Grown as: Cabbage is a biennial plant but it is grown as an annual. For seed production it is biennial.
Days to Maturity: 70 days
Hardiness: Hardy. Very hardy and can withstand early frost once plant is established.
Crops: Spring Transplant, Spring, Fall
Growing Season: Short, Long
Growing Conditions: Cold, Cool, Short days. The ideal spot for Pak Choi depends on the weather. If it's cool they should be planted on a sunny site. If it's warm then some shade is a good idea. Pak Choi are in and out of the ground quickly, so are often used for intercropping between slower growing crops, rather than being given their own area of bed.
Outdoor Growing Temp: 45°F - 75°F
Min Outdoor Soil Temp: 45°F. Pak Choi germinates and grows quickly (if the soil is at least 45 degrees) so is usually planted outdoors.
Start Indoors: Yes
Start Outdoors: Yes
Light: Sun: min. 6 hours daily (Cold, Cool). Full sun.
Water: High. Pak Choi needs a regular water supply to grow well, so keep the soil evenly moist.
Feeder: Heavy. Compost and aged manure are recommended to be dug into the soil. They prefer heavy soil with lots of organic matter to retain moisture and lots of available nutrients.
Suitability: Tolerates light frost, Needs summer shade.
Small Gardens?: Yes
Containers?: Yes. Shallow-rooted Pak Choi does well in a container. Make sure that your container has at least one drainage hole and fill with a mixture of potting soil and compost. Place your container in full sun as long as the temperature allows for this. In warmer climates, Pak Choi will need shade. Make sure the soil stays moist by watering regularly.
Attracts beneficial insects?: No
Maintenance: Medium
Plant Height: 6-18"
Spacing: 18-24"
Sow Depth: 1/4"
Hardiness Zone: 2-11
Produces: a head of smooth, dark green leaves with thick white stalks.
Garden Uses: Vegetable gardens.
Soil Preparation
Soil pH: 6.0-7.5, Ideal 7.0-7.5
Cabbages are hungry plants and must have rich soil if they are to produce well. They prefer heavy soil with lots of organic matter to retain moisture and lots of available nutrients (especially potassium and phosphorus). They don't need a lot of nitrogen however, as this can lead to sappy growth that isn't very hardy. It doesn't like poorly drained soil. Potential micronutrient deficiencies include boron and manganese. Early crops may do better in lighter soils that warm up more rapidly, or in raised beds.
Soil Preparation:
Compost (Nitrogen), 2" in top 6" of soil, 1 time: Cabbages love organic matter, so incorporate 2˝ of compost or aged manure into the top 6˝ of soil. If this is applied the previous fall, fresh manure can be used.
Standard Mix, 5 pounds per 100 sq. ft., in top 6" of soil, 1 time: This standard mix will supply additional phosphate, wood ashes, kelp and dolomite limestone. This should be incorporated into soil along with the compost.
This is a mix of various amendments intended to supply all of the nutrients plants may require. It is usually incorporated into the soil prior to planting. The mix consists of:
- 4 parts cottonseed meal (this is high in nitrogen and relatively inexpensive)
- 2 parts colloidal phosphate or bone meal (for phosphorus)
- 2 parts wood ash or 3 parts greensand or granite dust (for potassium)
- 1 part dolomitic limestone (to balance pH and add calcium and magnesium)
- 1 part kelp meal (for trace elements)
Mix these together thoroughly. You can do this all at once, or you can store them separately and mix as needed.
Start Indoors
Soil temp for germination: 45°F to 80°F, optimal 50°F to 75°F, optimal 70°F
Total weeks to grow transplant: 6 to 8 (Spring/Summer), 7 to 9 (Fall/Winter)
Germinate:
4-6 weeks before last frost date: Greens don’t really like transplanting (it may contribute to bolting) so plant it in cell packs or soil blocks and be very careful. If the weather gets very cold after planting out, protect the young plants with cloches, until temperatures are well above 50˚ F.
Transplant Outdoors
Cold, Cool, Short days: The ideal spot for Pak Choi depends on the weather. If it's cool they should be planted on a sunny site. If it's warm then some shade is a good idea. Pak Choi are in and out of the ground quickly, so are often used for intercropping between slower growing crops, rather than being given their own area of bed.
When outdoor temp: 45°F to 75°F, optimal temp 60°F to 65°F.
When min soil temp: 45°F. Pak Choi germinates and grows quickly (if the soil is at least 45 degrees) so is usually planted outdoors.
Spacing: 8-12", 1 plants per sq ft. Space Pak Choi 12" apart after thinning.
Intensive beds: Plant Pak Choi 3 to 4 inches apart at first. When the plants have 4 to 5 leaves on them, thin them to 6 inches.
Support: No
Start Outdoors

When min soil temp: 45°F. Pak Choi germinates and grows quickly (if the soil is at least 45 degrees) so is usually planted outdoors.
Seed Depth: 0.25"-0.5". Sow the seed 1/4" deep in cool soil and 1/2" deep in warm soil.
Spacing: 8-12", 1 plants per sq ft. Space Pak Choi 12" apart after thinning.
Intensive beds: Plant Pak Choi 3 to 4 inches apart at first. When the plants have 4 to 5 leaves on them, thin them to 6 inches.
Spring Crop:
2-4 weeks before last frost date: As the weather warms up, Choy can be sown directly outdoors. The plants grow well when direct sown, though there is a danger that they may end up as dinner for some of the many hungry pests that love Brassicas. This problem of predation is one reason it is common for them to be started indoors, where they are more easily protected.
Fall Crop:
8-10 weeks before first frost date: The plants grow well when direct sown, though there is a danger that they may end up as dinner for some of the many hungry pests that love Brassicas. This problem of predation is one reason it is common for them to be started indoors, where they are more easily protected.
Support: No
Water Needs: Moderate. Watering, regularly. Water, 0.5-1.0 gallon(s) per plant, regularly, 1 time a week Cabbages need a regular water supply to grow well, so keep the soil evenly moist. Heads may split if a heavy rain follows a long dry spell without irrigation. They are quite shallow rooted, so make sure there is plenty of moisture in the soil at all times. This is particularly important in hot weather. Consistent watering is also important. Lack of water can result in unpleasantly strong tasting plants and thicker, tougher leaves. At the other extreme, if plants are suddenly soaked after being very dry the resulting burst in growth can cause the head to split. It is best to use drip irrigation so the leaves don’t get wet, as several diseases can be spread in this way. Watering also depends on your local weather; don't water if it's raining, or water more frequently if it's dry. Just be sure to keep soil moist for the best crop. The best way to know how much moisture is in your soil is to feel 2" below the soil line. If it's dry, water.
Fertilizer Needs: Heavy. Cabbages are hungry plants and must have rich soil if they are to produce well. They prefer heavy soil with lots of organic matter to retain moisture and lots of available nutrients (especially potassium and phosphorus). They don't need a lot of nitrogen however, as this can lead to sappy growth that isn't very hardy. Early varieties require a higher soil fertility than mid or late-season varieties.
Side Dressing, after planting: Compost tea, 5 gallon(s) per 100 sq. ft., after planting, 1 time. A liquid feed of compost tea is helpful in early spring, while the soil is cool and nitrogen is not readily available.
Side Dressing, at early fruit set: Compost tea, 5 gallon(s) per 100 sq. ft., at early fruit set, 1 time.
Give the plants another feed of compost tea as the plants start to head up to help them grow bigger.
Harvesting
Cut whole, these vase-shaped little heads are plump and well filled out.
Whole Plant, 28-56 days after maturity:
You can harvest single leaves, as soon as they get large enough (about 3˝ high). They are often grown in Mesclun salad mix and harvested this way.
You can also harvest by cutting the whole plants, leaving several inches of stem behind. The remaining stem will then resprout and grow again (you can sometimes cut them several times).
Cut and Come Again Option:
You can harvest single leaves, as soon as they get large enough (about 3˝ high). They are often found in Mesclun salad mix and harvested this way.

Storage Temp: 60-70°F
Storage Length: 180-360 days
Store well protected in a plastic bag.
Storage Req: Refrigerator
Storage Temp: 35-40°F
Storage Length: 1-14 days
Seed Viability in Years: 3-5 Years
Germination Percentage: 80%
Crisp stalks with green leafy flavor. Excellent for stir-fry recipies, soups or noodle dishes.
Culinary Use:
This delicate flavored Asian green is best known for stir-fry, braising, simmering in soups, and accompanying noodle and meat dishes. These greens can also be blanched and hung out to dry in the sun, which allows them to be stored throughout the winter.
Leaves: raw or cooked. A crisp, watery texture with a naturally sweet taste, it is best eaten raw in salads. The plant can be eaten as a young seedling, or left to grow into a mature plant. The flavor is quickly ruined by prolonged cooking. Leaves can also be dried for winter use. The heads of mature plants can be 19 1/2" long and weigh up to 10 lbs. Fresh leaves do not store well and are best used within a day or two of harvesting. A nutritional analysis is available.
Flowering shoots: raw or cooked. Sweet and tender.
Companions: Alternate with Brussels sprouts in the row. The form of the tall growing, bare stalked sprouts complements the loose heads of the Chinese cabbage, allowing good air circulation around the plants. Or plant Chinese cabbage at the base of pea trellises, where it will get some shade and wind protection. Some companion gardeners let spent Chinese cabbage plants stand as a trap crop for aphids; pull and destroy infested plants.
Enemies: None known.

Soft-winged Flower Beetle or Collops Beetle: Collops beetles are commonly found on Alfalfa and Cotton plants in agricultural fields, landscapes and gardens. The adult eats aphids and the larvae are active predators in the soil. Two abundant species in Utah are the two-spotted melyrid and the soft-winged flower beetle. Collops beetles are not commercially available.
Soldier Beetles: The adult stage of the soldier beetle eats aphids. The larvae live in the soil and help to control soil-borne pests. There are beetles that look similar to soldier beetles such as blister beetles and click beetles, so use care when identifying them. Soldier beetles are not commercially available.
Since Soldiers Beetles lay their eggs in the soil, all you have to do to is grow good nectar or pollen producing plants like Asclepias (milkweed), Solidago (goldenrod), and, while it’s not well understood, they seem particularly attracted to hydrangeas. Soldier Beetles can be found on flowers where they lie and wait for prey. They also feed on nectar and pollen but do not damage the plants.
Long-legged Flies: There are many species of long-legged flies (Dolichopodidae), the adults of which are predators of soft-bodied pests such as thrips, aphids, spider mites, flea hoppers, booklice, flies, silverfish, small caterpillars, and a variety of other small insects. They also eat nectar from flowers. The adult is recognized by the long legs and tapered abdomen but also by the metalic green or blue color. Larvae of long-legged flies are maggot-like in appearance and develop in wet or dry soil, rotting vegetation, or under bark. They are not commercially available.
Syrphid, Flower, or Hover Flies: Syrphid flies are about the size of house flies and hover in flight. The adults, which sometimes resemble bees, are not predaceous, but the larvae are aphid predators. The larvae vary in color from green to brown, some with a stripe or two down the back. The body tapers to the mouthparts. Syrphid flies are not commercially available.
