Green Cabbage

Head · Brassicaceae

Green cabbage is the most heat-tolerant of the heading brassicas, forming a single firm round head. Splitting is the main challenge: mature heads take up excess water after rain and crack. Early varieties (60 to 65 days) are best for spring, while late varieties (100 days and up) are for fall storage. It is a storage champion, keeping 3 to 6 months in a root cellar at 32 to 40F and 95 percent humidity, which historically made it one of the most important winter vegetables. It is also one of the most versatile in the kitchen. Key facts: 60–100 days to maturity, 6+ hours of sun, 12–18 " spacing. Container-friendly (minimum 5-gallon pot).

Heat: Low Cold: High

Watch for these first

Sort
Issue Severity Category Peak window
Black leg (brassica) Leptosphaeria maculans (Phoma lingam)
High Disease May–Aug Peak window months: May, Jun, Jul, Aug.

A soilborne and seedborne fungus that rots the stem near the soil line and produces sunken cankers dotted with tiny dark fruiting bodies. Leaves yellow, plants are stunted, and badly affected plants topple or fail to grow. It is most damaging in cool, moist soil, and secondary rots like white mold and soft rot often follow.

Triggers: Most important in cool, moist soil. Spreads on infected seed and in crop debris; spores splash to stems in wet weather. Tiny dark fruiting bodies (pycnidia) in the stem cankers are diagnostic.

Risk fades when: Drier conditions slow splash spread. Four dry days reduces active risk; stem cankers remain.

Black leg (brassica) symptoms
Pathogen: Cercospora beticola — Photo: Plant pests and diseases · CC0 1.0
Black rot Xanthomonas campestris pv. campestris
High Disease Mar Peak window months: Mar.

A brassica-specific bacterial disease causing yellow V-shaped lesions that start at the leaf margins, blackened veins, and gradual whole-plant decline. Affects brassicas only (including brassica-family root crops via specific overrides). Despite the name, it's unrelated to grape or kiwi black rot.

Triggers: Warm wet weather, dew collecting at leaf margins, splashing water, and infected seed or transplants all favor bacterial spread.

On Green Cabbage: Warm, wet conditions and contaminated residue can spread bacterial leaf-vein infection.

Prevention: Use clean seed or transplants, rotate away from brassicas, and avoid overhead irrigation.

Risk fades when: Moisture drives new infection. Dry weather reduces new pressure, though existing infections and soil inoculum persist.

Blindness Apical meristem damage
High Physiological Fall Peak window months: Sep, Oct, Nov.

Blindness in brassicas is when the central growing point (apical meristem) is damaged before head formation, so the plant grows vegetatively but never produces the central head you planted it for. Causes include: severe cold injury below 25°F killing the meristem, cabbage looper or cabbage worm feeding directly on the growing tip, mechanical damage during transplanting, or boron deficiency in extreme cases. The plant otherwise looks healthy — full leaves, vigorous growth — but no head forms. Some plants compensate by producing side shoots from leaf axils (lateral broccoli florets) which can be harvested. Prevention: protect from extreme cold during early growth, control cabbage worms, handle transplants carefully.

Triggers: Meristem damage from cold, pest feeding, mechanical injury, or severe boron deficiency. Plant continues vegetative growth but skips head formation entirely.

Risk fades when: Blind plants won't produce a central head. Sometimes side-shoot florets develop from leaf axils — harvest those. Otherwise the plant is a loss for head production. Compost and replant for fall harvest.

Bolting Vernalization-induced bolting
High Physiological Dec Peak window months: Dec.

Brassicas are biennial plants from the Mediterranean — they expect a winter cool period to trigger flowering. When spring transplants experience temperatures below 50°F for 2-8 weeks during early growth, they're 'vernalized' (cold-primed to flower). When warm summer days arrive, the plant skips its head-formation stage and shoots up a flower stalk. Different brassicas need different vernalization periods: long-maturing cabbage needs up to 20 weeks of cold to flower; early Chinese cabbage and cauliflower need as little as 1 week. Plants only respond to cold once they've reached 2-15 true leaves — that's why broccoli set out too early (too small) or too cold often bolts.

Triggers: Per MSU/UMN/UDel Extension: cold exposure below 50°F for 2-8 weeks during 2-15 leaf stage triggers vernalization. Warming to >61°F devernalizes some species (cabbage, Chinese cabbage, kohlrabi) but not others. Distinguish from 'buttoning' (premature small head from too-early cold) which occurs in undersized plants. Bolting hits mature plants AFTER vernalization, driven by heat/stress.

Risk fades when: Once vernalized + stressed, brassicas commit to flowering. The current crop is done. Fall plantings (mid-summer sowing, late-summer transplant) rarely bolt because they vegetatively grow in declining day length and harvest before next year's vernalization.

Buttoning Premature vernalization-induced head formation
High Physiological Winter Peak window months: Jan, Feb, Dec.

Buttoning is the opposite mistake from bolting — instead of skipping head formation entirely (bolting), the plant forms a tiny premature head before it has enough leafy biomass to support normal growth. It happens in broccoli and cauliflower when undersized plants (under 2-4 leaves) experience prolonged cold below 50°F. The plant interprets the cold as 'winter complete' and shifts to reproductive mode prematurely. Result: a button-sized head on a small plant that won't size up regardless of subsequent care. Most common in early-spring transplants set out before nights stay above 50°F. Bolting hits mature plants AFTER vernalization; buttoning hits young plants DURING vernalization. Wait to transplant until nights are reliably above 50°F, or use row cover for cool nights early in the season.

Triggers: Per MSU/UMN Extension: cold exposure below 50°F on plants with fewer than 4 true leaves triggers premature head formation. Distinguish from bolting which hits mature plants AFTER vernalization.

Risk fades when: Buttoned plants won't size up. Pull and replant with appropriate timing. The current planting is a loss.

Clubroot Plasmodiophora brassicae
High Disease May–Aug Peak window months: May, Jun, Jul, Aug.

A brassica-specific soil-borne disease that forms swollen, distorted roots and causes plants to stunt or wilt during the heat of the day. Infects brassicas only (including brassica-family root crops via specific overrides) — it won't affect carrots, beets, or other non-brassica root vegetables.

Triggers: Moist, acidic soils plus water movement favor the swimming zoospores that infect roots. The pathogen persists in soil for years once established.

Risk fades when: Moisture drives new infection. Dry weather reduces immediate pressure, though existing infections and soil inoculum persist for the long term.

Corn earworm / tomato fruitworm Helicoverpa zea (= tomato fruitworm = cotton bollworm = soybean podworm)
High Pest Jul–Sep Peak window months: Jul, Sep.

Corn earworm is the same species as tomato fruitworm and cotton bollworm — a polyphagous caterpillar that bores into ears of corn through fresh silks, into tomato and pepper fruit, into lettuce heads, and into bean and pea pods. In sweet corn, losses can reach 50%. The species migrates north annually from southern overwintering grounds; in much of the northern US, it does not survive the winter when temperatures drop below 30°F.

Triggers: Overwinters as pupa in top 2-4 inches of soil where winter temps permit. North of I-70 (Illinois IPM): does not reliably overwinter — populations arrive via migration mid-July through September. Females prefer fresh corn silks for egg-laying; older silks rejected.

Risk fades when: Wisconsin Hort, Illinois IPM

Damping off Pythium spp. / Rhizoctonia solani / Fusarium spp.
High Disease May–Aug Peak window months: May, Jun, Jul, Aug.

A seedling killer caused by several different fungi working together. It hits vegetables, flowers, herbs, microgreens, and cover-crop seedlings the same way — seeds rot before they emerge, or young seedlings collapse right at the soil line. Wet seed-starting mix and poor airflow in seedling trays are the classic conditions.

Triggers: Wet soil or starting mix, poor drainage, seedlings packed too tightly, contaminated trays or media, and stagnant air all favor damping-off.

Risk fades when: Drying the soil surface and improving airflow slows new spread. Collapsed seedlings don't recover, but the rest of the tray can be saved.

Imported cabbageworm Pieris rapae
High Pest Winter Peak window months: Jan, Feb, Dec.

The imported cabbageworm is the most important caterpillar pest of brassicas in much of the United States. Adults are the familiar small white butterflies with one or two black spots on each forewing, conspicuous as they flutter low over cabbage and broccoli plants on warm days. The velvety green caterpillars blend into foliage and do their damage hidden among inner leaves, often boring into developing heads.

Triggers: Adults active during daytime in warm weather. Female lays 400-1000 single eggs over 5-20 day adult life. 2-4 generations in north, 6-8 in south. Eggs hatch in 4-10 days; larvae through 5 instars in 10-14 days.

On Green Cabbage: Caterpillars chew leaves and tunnel into heads.

Prevention: Use floating row cover after transplanting and scout often.

Risk fades when: Overwinters as pupa attached to plant debris per Oklahoma State Extension

Root maggot complex Delia spp. complex: D. radicum (cabbage maggot), D. platura (seedcorn maggot), D. florilega, D. planipalpis
High Pest Jan–Dec Peak window months: Jan, Dec.

The Delia root-maggot complex includes the cabbage maggot (D. radicum) on brassicas and root crops, the seedcorn maggot (D. platura) on bean/pea/corn seedlings, and several other species. Larvae tunnel into roots, basal stems, and seeds, killing seedlings outright or creating tunnels that ruin root crops for market. A 2021 Oregon industry survey found 100% of root crop growers reported cabbage maggot damage; 44% with 10-25% yield loss.

Triggers: Overwinter as pupae in soil/crop residue. Adults emerge early spring (300-600 GDD base 40°F after Jan 1 in PNW). Cool moist soils favor egg survival; soil >95°F in top 2-3 inches kills eggs. Multiple generations per year. Seedcorn maggot attracted to decaying organic matter — high risk after fresh-incorporated cover crop.

Risk fades when: U Maine

Tip burn Calcium transport disruption (internal browning)
High Physiological Summer Peak window months: Jun, Jul, Aug.

Cabbage tipburn (sometimes called 'internal browning') is calcium-transport failure inside the head. Inner leaves are growing fast and demand calcium, but the closed head structure makes them poorly-transpiring — they can't pull calcium up with water flow like outer leaves can. When growth outpaces calcium delivery, the margins of those inner leaves collapse and turn brown. Often unnoticed until the head is cut open. Most common in fast-growing summer cabbage. Slower-maturing varieties and steady moisture both reduce the risk. The same calcium-cascade mechanism causes blossom-end rot in tomatoes and tipburn in lettuce — same physiology, different host.

Triggers: Closed head structure means inner leaves transpire poorly + can't pull calcium with water. Fast-growing summer cabbage most susceptible.

Risk fades when: Once internal browning forms, the head is compromised. Cut and discard affected portions or compost. Plant slow-maturing varieties and provide steady moisture for next planting.

White mold / Sclerotinia (brassica) Sclerotinia sclerotiorum, Sclerotinia minor
High Disease May–Aug Peak window months: May, Jun, Jul, Aug.

A watery soft rot of stems, lower leaves, and heads. Infected tissue turns into a soft, watery decay, plants wilt and collapse, and dense white cottony growth with hard black resting bodies forms on and inside the stems. It is favored by cool, moist conditions and wet soil, and the resting bodies survive in soil for years.

Triggers: S. minor infects stems and leaves touching the soil; S. sclerotiorum also forms small mushroom-like apothecia that release airborne spores infecting upper leaves and flowers. Wet conditions and dense canopies raise risk; sclerotia persist in soil for years.

Risk fades when: Drying conditions slow new infection. Five dry days exits the active window; established rot does not reverse and sclerotia persist in soil.

Alternaria leaf spot Alternaria brassicicola / A. brassicae / A. raphani
Moderate Disease May–Aug Peak window months: May, Jun, Jul, Aug.

A brassica-specific Alternaria disease that causes dark target-like spots on the leaves and rot in the heads of cabbage-family crops. It infects brassicas only (including brassica-family root crops like turnips and radishes via specific overrides) — it won't show up on carrots or beets.

Triggers: Cool to warm wet conditions, wind, rain, and infected seed or plant debris all favor spread and infection.

Risk fades when: Moisture drives new infection and spread. Dry weather reduces new pressure, though existing infections and inoculum in the soil persist.

Aphids Multiple genera: Myzus persicae (green peach aphid), Aphis gossypii (melon aphid), Macrosiphum euphorbiae (potato aphid), Brevicoryne brassicae (cabbage aphid)
Moderate Pest Mid-summer Peak window months: Jun, Jul, Aug.

Aphids are soft-bodied sap-sucking insects that cluster on tender new growth. Most established plants tolerate moderate populations and will outgrow damage on their own, but aphids are the most important plant virus vectors in the garden, transmitting more than 100 plant viruses including potato leafroll, cucumber mosaic, and turnip mosaic. Honeydew excreted while feeding supports sooty mold growth and attracts ants that protect aphids from natural enemies.

Triggers: Optimal development at ~75°F (green peach aphid) per UC IPM Floriculture; melon aphid develops fastest above 75°F. Many species heat-intolerant above 90°F and crash in mid-summer. Soft new growth and over-fertilization with high N favor population buildup. Females give live birth parthenogenetically most of growing season — one generation in ~1 week under optimal conditions.

Risk fades when: Per UC IPM and Clemson HGIC, populations crash in mid-summer heat (>90°F) for many species, return in cooler conditions

Downy mildew (brassica) Hyaloperonospora parasitica
Moderate Disease Summer Peak window months: Jun, Jul, Aug.

A cool-weather foliar disease most damaging on seedlings and young plants. It shows as faint yellow spots on the upper leaf surface with a white to gray fuzzy growth on the underside. On heads and curds it can cause dark speckling that downgrades quality. It is driven by cool temperatures, leaf wetness, and high humidity.

Triggers: Favored by cool temperatures and prolonged leaf wetness or high humidity. Most serious on seedlings, where it can kill young plants; on older plants it spots leaves and can speckle heads.

Risk fades when: Warm, dry weather suppresses it. Three dry days with highs above 75°F exits the active window; spotted leaves stay damaged.

Flea beetles Phyllotreta cruciferae (crucifer), Epitrix spp. (potato/tuber/eggplant), Phyllotreta striolata (striped)
Moderate Pest Mar–Jun Peak window months: Mar, Jun.

Flea beetles are small (1/16-inch) shiny beetles that jump like fleas when disturbed. They chew small round 'shothole' or 'pinhole' damage in leaves and can destroy emerging cotyledons of broccoli or eggplant in 24 hours. Most species are host-family specific — crucifer flea beetle on brassicas, tuber flea beetle on potatoes, eggplant flea beetle on solanaceous crops.

Triggers: Overwinter as adults in leaf litter and field margins. Active at mid- to late-spring temperatures. Warm winter → higher next-spring populations (NC State). Hot dry conditions amplify damage on stressed seedlings.

Risk fades when: UMN: 1-2 generations in Minnesota, populations crash after mid-June

Fusarium yellows (cabbage) Fusarium oxysporum f. sp. conglutinans
Moderate Disease Year-round Peak window months: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.

A warm-soil wilt that turns leaves a dull yellow-green, often more on one side of the plant, with downward curling and leaf drop from the bottom up. Cutting the stem shows brown discoloration of the water-conducting tissue. Unlike most brassica diseases it is favored by warm soil, and the fungus persists in soil for years.

Triggers: Favored by warm soil (roughly 80-90°F). The fungus enters through the roots and clogs the water-conducting tissue, causing one-sided yellowing and wilt. It survives in soil for many years; resistant cabbage varieties are the main defense.

Risk fades when: Activity slows as soils cool below about 75°F. Seasonal pressure fades, but the fungus persists in the soil for many years.

Head splitting Mature heads absorb water rapidly after dry conditions or heavy rain.
Moderate Physiological No data

Mature heads absorb water rapidly after dry conditions or heavy rain.

On Green Cabbage: Mature heads absorb water rapidly after dry conditions or heavy rain.

Prevention: Keep soil moisture even and harvest promptly once heads are firm.

Hollow stem Boron deficiency or rapid-growth hollowing
Moderate Physiological Year-round Peak window months: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.

Hollow stem is what it sounds like — the main stem of broccoli or cauliflower develops a cavity, usually visible when you cut the head off. There are two distinct causes that look slightly different inside. Boron deficiency hollow has watery tissue that browns or blackens over time, with visible brown patches in the stem wall. Rapid-growth hollow (from excess nitrogen, hot weather, or wide spacing) has clean bright tissue inside the cavity — no browning. Boron deficiency is most common in sandy soils with low organic matter where boron leaches out easily, or in high-pH soils where boron is locked up. Excess nitrogen pushes the plant to grow faster than the central stem can keep up, leaving the cavity. Wider plant spacing (16+ inches) increases the per-plant nutrients available, which accelerates growth and increases hollow risk. The fix is the opposite: close spacing (10-12 inches), moderate nitrogen (no more than 3.5 lb N per 1000 sq ft), and a soil test for boron levels. If the test shows low boron, side-dress with a small amount — but be cautious because boron toxicity is just as serious as deficiency.

Triggers: Per MSU/UDel/WSU/UMN Extension: dual cause. Boron deficiency hollow shows brown/black discolored tissue inside (visible in stem wall). Rapid-growth hollow shows clean bright tissue inside. Sandy low-OM soils, high pH (above 7), and excessive nitrogen + wide spacing (16+ inches) all contribute. Spacing 10-12 inches reduces incidence significantly.

Risk fades when: Hollow stem doesn't make broccoli inedible — cut around the cavity. For next planting: soil test for boron, narrow spacing to 10-12 inches, moderate nitrogen, maintain pH 6.0-6.8. If boron test shows below 1 ppm, side-dress carefully; boron toxicity is just as serious as deficiency.

Slugs and snails Cornu aspersum (brown garden snail), Deroceras reticulatum (gray garden slug), Limax maximus, Arion spp.
Moderate Pest Spring Peak window months: Mar, Apr, May.

Slugs and snails are nocturnal mollusks that chew irregular holes in leaves and clip off succulent seedlings. They leave characteristic silvery slime trails. Hermaphroditic and prolific, brown garden snails lay around 80 eggs per month for up to six clutches per year.

Triggers: Active at night and early morning in damp conditions. Coastal CA and southeast — active year-round. Spring rains and dense ground cover (mulch, debris, weeds) create harborage.

Risk fades when: UC IPM

Thrips Frankliniella occidentalis (western flower thrips), F. tritici (eastern flower thrips), F. fusca (tobacco thrips), Thrips tabaci (onion thrips)
Moderate Pest Spring Peak window months: Mar, Apr, May.

Thrips are tiny (1/16 inch) slender insects with fringed wings that puncture and rasp leaf surfaces, leaving silver stippling with black frass dots. The biggest concern is virus vectoring: western flower thrips is the principal vector of tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV), which affect more than 600 plant species. Greenhouse and high tunnel infestations can be devastating.

Triggers: Hot dry weather; greenhouse/high tunnel environments. Female lays eggs inside leaf tissue. 2 larval stages feed; 2 non-feeding pupal stages in soil/litter. Lifecycle 10-21 days. Many overlapping generations. Bridge crops (spring wheat, peach, strawberry per NC State) build populations before vegetable hosts available.

Risk fades when: Wisconsin Hort, NC State

Leafminers Liriomyza sativae, Liriomyza trifolii, Pegomya hyoscyami (spinach), Phytomyza gymnostoma (allium)
Low Pest Sep–Oct Peak window months: Sep, Oct.

Leafminers are tiny fly larvae that feed between the upper and lower surfaces of leaves, creating winding pale tunnels or blotchy patches. They rarely kill plants but can ruin the marketability of leafy greens grown for foliage. Allium leafminer is an emerging pest in the eastern US (first detected in Pennsylvania in 2017) that damages onions, garlic, leeks, and chives.

Triggers: Liriomyza trifolii: 1 generation in ~1 month at typical greenhouse temps, 14 days at 95°F, 64 days at 59°F (UC IPM). Adults active mid-day. Allium leafminer emerges late March-early April, second flight September-October. Broad-spectrum insecticides trigger outbreaks by killing parasitoids.

Cool-season brassica seed-starting tray

UMN Extension says gardeners should start cabbage indoors for a spring-planted summer crop because a late direct-seeded crop would mature during the hottest part of summer, reducing quality. Transplants get crops out of the ground and into early production. Note that brassicas are cool-season crops and germinate well at 60 to 75 degrees Fahrenheit, so a heat mat is not necessary and can actually push germination too fast and produce weak seedlings. Use the cell tray and grow light, but skip the heat mat for brassica starts.
