How to Harvest Red Cabbage for Maximum Flavor and Storage

With its vibrant color and crisp, robust flavor, red cabbage makes a nutritious and delicious addition to many fall and winter dishes. However, harvesting the cabbage at the proper time is key to enjoying its full potential. Learning the right techniques for harvesting red cabbage will ensure your crop reaches peak taste and quality.

When is Red Cabbage Ready to Harvest?

Timing the harvest is one of the most important factors for success with red cabbage. Here are some signs that your cabbages are mature and ready for picking:

• Days to maturity – Check the seed packet or plant tag to find the days to maturity. Most red cabbage varieties are ready 80-100 days from transplanting. Add 20-30 days if growing from seed.

• Head size and firmness – Mature heads are generally 4-10 inches across. Test heads by squeezing gently. They should feel very firm and solid.

• Outer leaves loosening – As heads mature, the outer leaves open slightly and lose their tight wrapper leaves appearance.

• Deep color – Mature red cabbage heads will be a deep purple-red color. Avoid any heads that are pale or yellowing.

• Robust stem – A mature cabbage will have a thick sturdy main stem. Weak thin stems indicate immaturity.

Once most heads display these signs of maturity, your red cabbage is ready for harvest.

Harvesting Techniques for Red Cabbage

Use the following steps for harvesting flawless heads of red cabbage

• Cut heads with a sharp knife to avoid bruising or tearing. Leave 2-3 wrapper leaves intact to protect the head.

• Cut the main stem about 2 inches below the bottom of the head. Leave the stem attached to use as a handle.

• Gently lift and support the underside of large heads to avoid breakage.

• Harvest all mature heads at once, leaving immature heads to continue growing. Make a second picking 7-10 days later.

• Harvest before heavy frost or freezing weather arrives to prevent split heads.

• Cut away any damaged outer leaves and wipe off any dirt before storing.

Proper harvesting technique preserves both quality and storage life of your red cabbage crop.

How to Store Harvested Red Cabbage

Red cabbage stores very well, lasting 2-6 months if stored properly after harvest. Here are some options for storage:

• Cool cellar or garage – Store whole heads unpacked in cool (32-40°F), humid conditions. Hang heads upside down by their stems.

• Refrigeration – Place whole heads in perforated plastic bags in the crisper drawer. Keeps 2-3 weeks.

• Freezing – Chop or shred heads, blanch for 1-2 minutes, cool, drain and pack into airtight freezer bags. Keeps 9-12 months.

• Canning – Red cabbage can be processed in a water bath canner using an acidic brine. Keeps 12+ months sealed.

• Fermenting – Shredded red cabbage makes a delicious fermented sauerkraut. Ferment for 2-4 weeks before refrigerating.

• Root cellars – Whole heads will store for several months in ideal cold, humid root cellar conditions.

Properly cured and stored, red cabbage will retain its freshness and flavor for months after harvest.

Avoiding Common Problems When Harvesting

Pay attention to these potential issues when harvesting red cabbage:

• Harvest before a heavy frost or freeze. Temperatures below 25°F can cause heads to split.

• Cut heads instead of pulling or twisting to avoid stem breakage and loose heads.

• Check outer leaves and remove any that are damaged, diseased or show insect damage.

• Heads that are exposed to sunlight after maturity can develop bitter or off flavors.

• Overmature heads are more prone to cracking and rot during storage. Harvest on time.

• Any injuries or bruising during harvest creates entry points for storage rot. Handle with care.

• Wash heads thoroughly after harvest to remove dirt and debris before storing.

With attentive harvesting and proper post-harvest storage, your homegrown red cabbage will provide a bounty of colorful, crunchy goodness all winter long. Enjoy this flavorful and versatile cold weather crop!
