39 Great Companion Plants For Cabbage

Sharing is caring!

A cabbage is a biennial plant cultivated as an annual vegetable for its heads which have densely packed leaves. These leaves may be green, pale green, red, purple or white in color. It is a close relative of broccoli, Brussels sprout and cauliflower.

It belongs to the biological family known as Brassicaceae, which is also known as the cabbage family. Cabbages come in different shapes, colors and sizes, weighing usually between 0.5 and 1 kg (1 to 2 pounds).

The most common ones have smooth leaves, firm heads and green coloration. The rarest ones have crinkled leaves that are purple in color. Cabbage may grow very large when planted in very sunny areas.

Raw cabbages contain 92% water, about 6% carbohydrate, 1.3% protein and trace amounts of fat. They provide vitamins A, B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B9 (folate), C, E and K, calcium, iron, magnesium, manganese, phosphorus, potassium, sodium and zinc.

For consumption, they may be prepared by braising, pickling, fermentation, roasting, sautéing, steaming or stewing, and they may be eaten raw as well. Cabbages are best grown in full sun, for 6 or more hours daily.

They also need to be grown in rich, well-drained, consistently moist soil with pH of between 6.5 and 7.0. Deep watering is needed at intervals to maintain soil moisture. It is susceptible to clubroot, a fungal disease, and the infestation of pests.

Cabbage is also prone to nutrient deficiencies and bacterial diseases but there are several other crops which may be planted with it in your garden to encourage its growth, help keep pests away, attract useful insects, replenish soil nutrients and provide ground cover or shade from sunlight.

Such grouping for the purpose of sharing benefits is called companion planting. It is a tried and true method, ensuring for years that crops are grown with some other crops that help them grow healthy.

In this article, you will learn about thirty nine (39) good companion plants and thirteen (13) bad companion plants for cabbage in your garden. Also explained below are reasons why they are or are not ideal beside your plant.

Conclusion

Cabbages are edible biennial plants in the Brassicaceae family cultivated for their heads which have densely packed leaves. Listed and explained above are thirty nine (39) good and thirteen (13) bad companion plants for cabbages.

These brassicas may have green, pale green, red, purple or white leaves. They contain mostly water (about 92%), then carbohydrates, protein and very little amounts of fat. They are also rich in vitamins and minerals. 

Cabbages provide the several vitamins and minerals such as vitamins A, B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B9 (folate), C, E and K, calcium, iron, magnesium, manganese, phosphorus, potassium, sodium and zinc.

Some health benefits of cabbages include that they: may keep inflammation in check, provide lots of vitamin C, help improve digestive functions within the body, aid heart or cardiovascular health, may lower blood pressure, may reduce body cholesterol levels and provide vitamin K.

They are cruciferous vegetables that protect heart health, reduce the chances of cancer in the body and strengthen the body against various diseases because of the antioxidants they contain.

While growing cabbages, remember that they need to be exposed to full sun, for 6 or more hours daily. They are best grown in rich, well-drained, consistently moist soil with pH of between 6.5 and 7.0. Their soil needs to be thoroughly watered at intervals to maintain healthy amounts of moisture.
