Most cabbage plants produce one main head, and that head weighs about 1 to 3 pounds for small early varieties or 4 to 8 pounds or more for large late varieties. If you cut the head carefully and leave the stem and lower leaves in place, the same plant often adds 2 to 4 small bonus heads afterward.
So when you ask how much cabbage does one plant produce, the honest number for a home garden sits somewhere between 1 and 10 pounds. The variety you pick sets the ceiling. Your soil, water, spacing, and weather decide how close you get to it.
Why One Main Head Is the Standard Harvest
A cabbage plant puts nearly all its energy into one tight bud at the top of a short stem, so one firm head per plant is the normal harvest. Plan your garden around that single head, and treat anything extra as a bonus.
What Counts as a Harvestable Cabbage Head?
A harvestable head is a ball of tightly wrapped leaves that feels solid when you squeeze it. Loose, open rosettes of leaves don’t count yet, even if the plant looks big.
The head sits inside a ring of large outer “wrapper” leaves. Those outer leaves feed the head through the season, but most people trim them off in the kitchen. When I talk about yield, I mean the trimmed, usable head.
Head shape varies. Some are round, some are flat like a drum, and pointed types form a cone. All of them should feel dense, with no hollow give in the middle.
How Much Can You Expect From One Plant?
Here’s a realistic range for a home gardener growing cabbage (Brassica oleracea var. capitata):
| Variety type | Days from transplant | Main head weight | Possible extra from side heads |
|---|---|---|---|
| Small early | About 60 to 70 | 1 to 3 lb | 2 to 4 heads, baseball size |
| Midseason | About 70 to 85 | 2 to 4 lb | 2 to 4 small heads |
| Large late/storage | About 80 to 100+ | 4 to 8+ lb | Fewer, since fall cold cuts regrowth short |
To hit the upper end of those numbers, start with good cabbage seeds or sturdy transplants, then feed with a balanced vegetable fertilizer. A soaker hose under mulch makes the steady watering cabbage needs much easier to manage.
How Big Are Heads From Different Cabbage Varieties?
Head size comes down to genetics first. Early varieties stay compact and fast, late storage types grow huge and slow, and red and savoy cabbages fall in the middle with their own quirks.
Small Early Cabbages and Early Jersey Wakefield
Early cabbages mature in about 60 to 70 days from transplant and make heads of roughly 1 to 3 pounds. They’re a smart pick for spring, since they finish before summer heat arrives.
Early Jersey Wakefield is the classic example. It’s an old heirloom with a pointed, cone-shaped head that usually lands around 2 to 3 pounds. The heads are sweet and tender, and the plants fit closer together than big late types.
I like early varieties for small gardens and for anyone who wants a head that one household can finish in a week.
Large Late Cabbages
Late or storage cabbages need about 80 to 100 days or more after transplanting. In return, they can produce heads of 4 to 8 pounds or more, with dense, thick leaves that store for months.
These are the ones to grow for sauerkraut or winter storage. They need a long cool season, so most US gardeners plant them for a fall harvest. They also need more room, about 24 inches between plants.
Red and Savoy Cabbage
Red cabbage heads tend to run a bit smaller and denser than similar green types, often 2 to 4 pounds, and many red varieties take a little longer to mature.
If you’re deciding between them, my piece on red cabbage vs green cabbage compares flavor, color, and growing time.
Savoy cabbage (var. sabauda) has crinkled, puckered leaves and takes about 80 to 90 days. Its heads feel lighter for their size because the leaves pack loosely. You can read more on savoy cabbage vs green cabbage if you’re picking between the two.
What Makes a Cabbage Head Grow Larger or Smaller?
Big heads come from rich soil, steady nitrogen, and even moisture through the whole season. Small or cracked heads trace back to gaps in one of those three.
Soil Fertility and Feeding
Soil fertility sets the size of your harvest more than anything you do late in the season. Cabbage is a heavy feeder, and it builds the leaves that become the head early on.
Work 2 to 3 inches of compost or aged manure into the bed before planting. Aim for a pH of 6.0 to 7.5, with 6.5 to 6.8 as the sweet spot.
Feed nitrogen twice:
- About 3 weeks after transplanting: side-dress with a balanced vegetable fertilizer or a nitrogen-rich organic option.
- When the head starts forming: give a second side-dressing, then stop.
Skip heavy feeding once heads are firm. A late surge of growth is one cause of splitting.
Steady Water and Mulch
Give cabbage about 1 to 1.5 inches of water a week, every week. Dry spells stall the head, and stalled heads rarely catch up to full size.
A 2 to 3 inch layer of straw, shredded leaves, or grass clippings keeps the soil cool and evenly moist. Mulch also cuts down on weeds that steal nitrogen from shallow cabbage roots.
Why Heads Stay Small or Split
Small heads almost always come from one of these causes:
- Plants set too close together
- Heat above about 80°F during heading
- Too little nitrogen early in the season
- Uneven watering
- Root damage from clubroot or root maggots
Splitting happens when a mature head takes in a lot of water fast, usually a heavy rain or deep soak after a dry spell.
If a firm head is about to crack and you aren’t ready to pick, twist the plant a quarter turn or slice down beside it with a shovel. That breaks some roots and slows water uptake.
How Does Spacing Affect Your Harvest?
Wider spacing grows bigger heads, while tight spacing grows more, smaller heads in the same space. Pick your spacing based on the head size you want.
Spacing Cabbage in Garden Beds
In traditional rows, set plants 12 to 24 inches apart in rows 24 to 36 inches apart. Use the low end for early types and the high end for big storage cabbages.
In raised beds, I use about 18 inches for most varieties, 12 inches for small early types, and 24 inches for large late ones. My guide to cabbage spacing in a raised bed shows layouts for common bed sizes.
If you plant by the grid, the rule is one plant per square. Read more on growing cabbage in a square foot garden, and choose compact varieties for that layout so heads don’t crowd each other.
Measure your spacing evenly. Plants at uneven gaps mature at different times and sizes, which makes harvest harder to plan.
What to Expect From Container-Grown Cabbage
A container cabbage makes one smaller head, usually 1 to 3 pounds with a compact variety. The pot limits root room, and roots drive head size.
Use a pot at least 12 inches deep and about 5 gallons per plant. A 10-gallon pot is better if you want a full-size head.
Pots dry out fast, so check moisture daily in warm weather. For pot sizes and soil mixes, see my notes on growing cabbage in containers.
How Do Season and Temperature Change the Yield?
Cabbage grows its best heads at 60 to 70°F, so timing your planting to hit that window has a huge effect on yield. Heat shrinks or ruins heads, and the wrong kind of cold can make young plants bolt.
Spring and Fall Planting Windows
Spring crop: Start seed indoors 6 to 8 weeks before your last spring frost. Sow 1/4 to 1/2 inch deep; seeds sprout in about 4 to 10 days at 65 to 75°F. Harden seedlings off and transplant 2 to 4 weeks before the last frost.
Fall crop: Start seed 10 to 12 weeks before your first fall frost. Fall cabbage grows into cooling weather, so it often makes the biggest, sweetest heads.
Regional notes:
- Northeast, Midwest, Pacific Northwest: both spring and fall crops work; fall is best for large storage types.
- Southeast and Southwest (zones 8 to 10): grow cabbage through fall and winter, since spring warms up too fast.
Heat, Frost, and Premature Bolting
Once temperatures climb above about 80°F, heads turn loose or bitter, and plants may bolt by sending up a flower stalk. A bolted plant won’t form a usable head.
Cold is a different story. Established plants handle hard frost into the low to mid 20s°F, and a light frost sweetens the leaves.
The risk comes when young plants with pencil-thick stems sit at 40 to 50°F for several weeks. That chill can trigger bolting later, so don’t rush spring transplants out too early.
Which Pests and Diseases Can Cost You a Head?
Leaf-eating caterpillars and root diseases cause the most lost heads in home gardens. Covering plants from day one and rotating your beds prevent most of the damage.
Protecting Leaves From Common Cabbage Pests
The usual suspects:
- Imported cabbageworm: velvety green larva of a small white butterfly.
- Cabbage looper: green caterpillar that arches its back as it moves.
- Diamondback moth larva: small and wriggly; drops on a silk thread when disturbed.
- Flea beetles: tiny shot holes, worst on seedlings.
- Cabbage aphids: gray, waxy clusters in leaf folds.
- Cabbage root maggot: tunnels into roots and stunts plants.
- Harlequin bug: a problem across the South.
- Slugs and snails, plus rabbits, deer, and groundhogs.
