Growing Cabbage in Santa Cruz County | Green, Red, Savoy & Napa
Growing Cabbage in Santa Cruz County: From Green Heads to Red and Savoy
Cabbage is one of the most productive and versatile brassicas you can grow in Santa Cruz County, with some varieties yielding dense heads weighing 3 to 8 pounds from a single plant that occupies just two square feet of garden space. According to UC ANR, cabbage is among the most dependable cool-season vegetables for California's coastal regions, tolerating light frost, storing well after harvest, and coming in enough types (green, red, savoy, and napa) to keep your kitchen stocked for months. Our moderate temperatures and reliable rainfall make cabbage an excellent crop for gardeners at every skill level.
Cabbage (Brassica oleracea var. capitata, with napa cabbage classified as Brassica rapa var. pekinensis) has been cultivated for thousands of years and remains one of the world's most important food crops. In Santa Cruz County, we can grow all four major types, each with distinct characteristics, flavors, and uses.
What Types of Cabbage Can You Grow in Santa Cruz County?
Green Cabbage
The standard grocery store cabbage: round, dense, pale green outer leaves wrapping a tightly packed white interior. Green cabbage is the most forgiving and productive type, tolerating a wider temperature range than other cabbages. It is the best choice for coleslaw, sauerkraut, stir-fries, and stuffed cabbage rolls. Heads range from 2 to 8 pounds depending on variety and growing conditions.
Red (Purple) Cabbage
Similar in structure to green cabbage but with striking deep purple-red leaves colored by anthocyanins. Red cabbage tends to be slightly smaller and denser than green, with a mildly peppery flavor. The color brightens with acidic cooking (add a splash of vinegar) and fades in alkaline conditions. Red cabbage is packed with antioxidants and adds visual drama to salads and slaws.
Savoy Cabbage
Savoy cabbage has crinkled, deeply textured leaves that form a looser, more open head than standard green cabbage. The leaves are more tender and have a milder, slightly sweet flavor that makes savoy the best choice for fresh eating, delicate salads, and wraps. Savoy is also the most cold-hardy cabbage type, making it excellent for fall and winter growing in Santa Cruz County.
Napa (Chinese) Cabbage
Napa cabbage forms a tall, oblong head with crinkly, pale green leaves and thick white ribs. It is a different species (Brassica rapa) from the other three types and has different growing requirements: it is more sensitive to heat and day length, bolting quickly in long, warm days. Napa cabbage is essential for kimchi, wonderful in stir-fries, and has a mild, slightly sweet flavor. In Santa Cruz County, it grows best as a fall crop.
What Are the Best Cabbage Varieties for Santa Cruz?
Green Cabbage Varieties
Early Jersey Wakefield: One of the oldest American cabbage varieties, dating to the 1840s. It produces small to medium, pointed (conical) heads of 2 to 4 pounds in about 63 days from transplant. The pointed shape is charming and the flavor is excellent, sweet and mild. It matures quickly, making it ideal for spring planting when you want heads before warm weather arrives.
Golden Acre: A compact, round-headed variety that matures in about 60 to 65 days. Heads weigh 3 to 4 pounds and are dense enough for good slaw and sauerkraut. Golden Acre is a great small-garden variety because the plants are relatively compact. Well-suited to succession planting.
Late Flat Dutch (for storage): If you want large cabbage for winter storage or sauerkraut making, Late Flat Dutch produces broad, flat heads weighing 10 to 15 pounds. It takes 100 to 110 days to mature, so it is strictly a fall-planted, late-harvest crop. Plant in July for a November or December harvest.
Red Cabbage Varieties
Red Acre: The standard red cabbage for home gardens. It produces round, 3 to 4 pound heads with deep purple-red color in about 75 to 80 days. Red Acre is reliable, cold-tolerant, and widely available. It holds well in the field, meaning you do not have to harvest the instant it matures.
Kalibos: A stunning pointed red cabbage with a sweeter, milder flavor than most reds. The elongated, conical heads are beautiful sliced thin in salads. Kalibos matures in about 80 to 90 days and performs well in our coastal conditions.
Savoy Cabbage Varieties
Savoy Perfection: The classic savoy, producing crinkled, blue-green outer leaves surrounding a tender, loosely packed interior. Heads reach 3 to 4 pounds in about 85 to 90 days. Savoy Perfection is notably cold-hardy, making it an outstanding choice for Santa Cruz County's fall and winter garden. The texture and flavor are far superior to anything you will find in a store.
Alcosa: A faster-maturing savoy (about 72 days) that produces smaller, uniform heads. Good for gardeners who want savoy cabbage from a spring planting.
Napa Cabbage Varieties
Bilko: A widely adapted napa cabbage that produces tall, barrel-shaped heads weighing 4 to 6 pounds in about 55 to 60 days from transplant. Bilko has good bolt resistance for a napa cabbage, which is important because this species is prone to bolting in warm or long-day conditions. Best planted in mid to late summer for a fall harvest in Santa Cruz County.
Blues: A compact napa variety with good disease resistance and moderate bolt tolerance. Matures in about 57 days. Excellent for smaller gardens.
When Should You Plant Cabbage in Santa Cruz County?
Cabbage is more adaptable than cauliflower and tolerates a wider range of conditions, but timing still matters for the best results.
Spring Planting
Start seeds indoors: January through early February. Transplant outdoors: Late February through March. Harvest: May through June.
Spring cabbage benefits from our cool, moist spring conditions. Use early-maturing varieties (Early Jersey Wakefield, Golden Acre) to ensure heads form before any late-spring warmth arrives. Cabbage transplants can handle light frost, so do not hesitate to plant out in late February if conditions are mild.
Fall Planting (Best Overall Season)
Start seeds indoors: Late June through July. Transplant outdoors: August through early September. Harvest: October through January.
Fall is the premier cabbage season in Santa Cruz County. Plants establish in warm summer soil, develop large leaf canopies, and then form heads as temperatures gradually cool. Fall-grown cabbage heads are often denser, sweeter, and larger than spring-grown ones. Late-maturing varieties like Late Flat Dutch and Savoy Perfection are particularly good for fall planting.
Napa Cabbage Timing
Napa cabbage is the exception to the general cabbage planting schedule. Because of its sensitivity to bolting in warm, long-day conditions, napa cabbage should almost always be planted as a fall crop in Santa Cruz County:
Start seeds indoors: Late July through early August. Transplant outdoors: Late August through early September. Harvest: October through November.
Attempting to grow napa cabbage in spring almost always results in premature bolting. The increasing day length and warming temperatures trigger flowering before a head can form. UC Cooperative Extension materials consistently recommend fall planting for napa cabbage in coastal California.
How Do You Plant and Care for Cabbage?
Soil Preparation
Cabbage needs fertile, moisture-retentive soil with a pH between 6.0 and 7.5. Like all brassicas, it is a heavy feeder. Work in 2 to 3 inches of compost before planting and apply a balanced organic fertilizer. If clubroot has been a problem in your garden, raise the pH to 7.0 or above with lime, as clubroot thrives in acidic soil.
UC IPM's cabbage growing guidelines recommend incorporating about 0.2 pounds of actual nitrogen per 100 square feet before planting, with an additional side-dressing of nitrogen when heads begin to form.
Spacing
Spacing depends on the type and expected head size:
- Small/early varieties (Early Jersey Wakefield, Golden Acre): 12 to 18 inches apart in rows 24 inches apart.
- Standard varieties (Red Acre, Savoy Perfection): 18 to 24 inches apart in rows 24 to 30 inches apart.
- Large/storage varieties (Late Flat Dutch): 24 to 30 inches apart in rows 30 to 36 inches apart.
- Napa cabbage: 12 to 18 inches apart in rows 18 to 24 inches apart.
Wider spacing generally produces larger heads. Closer spacing yields smaller heads but more total production per square foot.
Watering
Consistent moisture is essential for cabbage, about 1 to 1.5 inches per week. Irregular watering is the primary cause of head splitting (more on that below). Drip irrigation is strongly recommended to keep foliage dry and reduce disease risk. Mulch with 2 to 3 inches of straw, leaves, or compost to maintain even soil moisture.
Fertilizing
Side-dress with nitrogen fertilizer when the plant begins forming a visible head (the inner leaves start cupping inward). Apply 1 tablespoon of blood meal or fish meal per plant, or water with liquid fish emulsion at full strength. Repeat 2 to 3 weeks later for large-heading varieties.
Cabbage that runs short on nitrogen produces small, loose heads with a stronger, more bitter flavor. Adequate nitrogen keeps the flavor mild and the heads dense.
How Do You Prevent Cabbage Heads From Splitting?
Head splitting is one of the most common and frustrating cabbage problems. A nearly mature head suddenly cracks open, sometimes dramatically, ruining the appearance and shortening storage life.
Splitting happens when the inner head grows faster than the outer leaves can expand to contain it. The most common triggers:
Uneven watering: A heavy rain or deep watering after a dry period causes the interior to swell rapidly. This is the number one cause of splitting in Santa Cruz County, often happening when fall rains arrive after a dry September or October.
Delayed harvest: Overripe heads that sit in the field too long are under increasing internal pressure and will eventually split. Harvest promptly when heads feel firm and solid.
Temperature fluctuations: Rapid swings between warm and cool conditions can accelerate internal growth while the outer leaves lag behind.
Prevention strategies:
- Water consistently. Drip irrigation on a timer is the best insurance against splitting.
- Harvest on time. When a head feels firm and solid when you squeeze it, cut it. Do not wait for it to get bigger.
- Root pruning. If you notice a head is mature but you are not ready to harvest, push the plant gently to one side to break some roots. This slows water uptake and buys you a few extra days. Some gardeners twist the plant a quarter turn instead. Both methods work by reducing the plant's ability to push water into the head.
How Do You Harvest and Store Cabbage?
Harvesting
Cabbage is ready to harvest when the head feels solid and firm when you squeeze it. A mature head should have little give. Cut the head from the plant with a sharp knife at the base, leaving the outer wrapper leaves attached (they protect the head during storage).
Timing tip: Harvest in the morning when heads are cool and crisp. In Santa Cruz County's mild climate, this is less critical than in hot areas, but morning-harvested cabbage still stores better.
Second harvest trick: After cutting the main head, leave the stem and root system in the ground. Many cabbage varieties will produce 2 to 4 smaller heads (about fist-sized) from the remaining stem. These "bonus" heads take 4 to 6 weeks to develop and are tender and sweet, perfect for a quick slaw or stir-fry.
Storage
Cabbage is one of the best-storing fresh vegetables. Proper storage conditions:
- Refrigerator: Whole, unwashed heads wrapped loosely in plastic keep for 1 to 3 months in the crisper drawer.
- Root cellar or cool garage: At 32 to 40 degrees with high humidity, green and red cabbage can store for 3 to 4 months or longer.
- In the garden: In Santa Cruz County's mild winters, cabbage can often be stored right in the ground. Mature heads tolerate light frost and can be harvested as needed through December, January, and even February.
Green and red cabbage store the longest. Savoy cabbage stores for 1 to 2 months (it is less dense and dries out faster). Napa cabbage stores for 2 to 4 weeks in the refrigerator.
Preservation
Sauerkraut: The classic way to preserve cabbage. Shred, salt, and ferment. Green cabbage (particularly Late Flat Dutch) makes the best sauerkraut.
Kimchi: Napa cabbage is the traditional kimchi base. Fall-harvested napa cabbage, fermented with Korean chili flakes, garlic, ginger, and fish sauce, produces a probiotic-rich condiment that keeps for months in the refrigerator.
Freezing: Blanch shredded cabbage for 90 seconds, cool in ice water, drain, and freeze. Frozen cabbage works well in cooked dishes but loses its crisp texture.
What Pests and Diseases Affect Cabbage in Santa Cruz County?
Cabbage shares most pest and disease issues with other brassicas (see also our guides to growing broccoli and growing Brussels sprouts). The primary concerns for Santa Cruz County:
Imported cabbageworm: The green caterpillars of the white cabbage butterfly. They chew large holes in leaves and can bore into developing heads. Row covers are the best prevention. Bacillus thuringiensis (Bt) is effective for active infestations, as recommended by UC IPM.
Cabbage aphids: Gray-green aphids that cluster on inner leaves and in developing heads. A strong water spray dislodges them. Encourage natural predators (ladybugs, lacewings, parasitic wasps).
Slugs and snails: Our moist coastal climate supports large populations. Young transplants are particularly vulnerable. Use iron phosphate bait (Sluggo) around plants. Evening hand-picking is effective if unpleasant.
Clubroot: A devastating soil-borne disease that causes swollen, distorted roots and stunted growth. More prevalent in acidic soils. Maintain pH above 7.0 and practice a 4-year rotation for brassicas. Once established, clubroot spores persist in soil for 10 to 20 years, according to UC IPM.
Black rot: A bacterial disease that causes V-shaped yellow lesions on leaf margins. Spread by splashing water and contaminated tools. Remove infected plants immediately. Use disease-free seed and transplants. Drip irrigation (rather than overhead watering) reduces spread.

Can You Grow Cabbage Year-Round in Santa Cruz County?
Nearly. With proper planning and variety selection, you can have fresh cabbage from the garden for 9 to 10 months of the year:
- January through March: Harvest overwintered fall-planted cabbage and savoy.
- April through June: Harvest spring-planted early varieties.
- July through August: The gap. Spring cabbage is finished and fall cabbage is not ready yet. This is when stored cabbage from the spring harvest fills in.
- September through December: Begin harvesting fall-planted cabbage.
Succession planting within each season extends the harvest further. Planting a new batch every 3 weeks during the spring and fall windows keeps fresh heads coming for months. For detailed timing across all brassica crops, see our brassica planting calendar.
Frequently Asked Questions
Why are my cabbage leaves turning purple?
Purple or reddish discoloration on green cabbage leaves (not red cabbage, where it is normal) usually indicates phosphorus deficiency. This is most common in early spring when cold soil temperatures reduce phosphorus availability to roots. The problem typically resolves on its own as soil warms. If it persists into warmer weather, a side-dressing of bone meal or rock phosphite can help. Severe cold stress can also cause purpling.
How do I know when napa cabbage is ready to harvest?
Napa cabbage is ready when the head feels firm and dense when you squeeze it gently from the sides. The head should be 10 to 12 inches tall and the outer leaves should be tightly wrapped. Unlike round cabbage, napa does not get rock-hard, so expect some give when you squeeze. Harvest promptly when mature, as napa cabbage deteriorates faster in the field than green or red types.
Can I direct-sow cabbage seed or do I need transplants?
You can direct-sow cabbage, but transplants give better results in most situations. Transplants let you start seeds in controlled indoor conditions, gain 4 to 6 weeks of growing time, and set out stocky, well-rooted plants. If you want to direct-sow, do it for the fall crop: sow seeds 1/4 inch deep in July, then thin to proper spacing when plants have 3 to 4 true leaves. The warm summer soil ensures quick germination.
What causes cabbage to taste bitter?
Bitter cabbage is usually caused by heat stress during head formation, nitrogen deficiency, or harvesting past peak maturity. Cabbage that matures during warm weather (above 80 degrees) tends to develop stronger, more sulfurous flavors. Fall-grown cabbage in Santa Cruz County is almost always milder and sweeter than spring-grown because heads develop in cooling temperatures. Adequate nitrogen and consistent watering also promote mild flavor.
How far apart should I plant different cabbage types?
For eating purposes, you can plant different cabbage types right next to each other. They will not cross-pollinate in a way that affects the current season's harvest. Cross-pollination only matters if you are saving seed, in which case different Brassica oleracea varieties (green, red, savoy) need isolation of at least half a mile. Napa cabbage (Brassica rapa) will not cross with the others at all since it is a different species.
Is ornamental cabbage edible?
Ornamental cabbage and kale are technically edible, as they are the same species (Brassica oleracea) as culinary cabbage. However, they have been bred for appearance rather than flavor, and most people find them tough and bitter compared to culinary varieties. They are also often treated with ornamental plant pesticides not approved for food crops. Grow dedicated culinary varieties for eating.
Cabbage is one of the most productive returns on garden space you can get in Santa Cruz County. A single plant can yield a 5-pound head that fills a crock of sauerkraut or feeds a family for a week of meals. Our coastal climate is a natural fit for this crop, and with four types to explore (green, red, savoy, and napa), there is always something new to try.
