Understanding Collard Greens

Collard greens (Brassica oleracea) are a member of the cabbage family, Brassicaceae. They are a leafy green vegetable that is commonly consumed in the Southern United States. Unlike some of their family members, collard greens do not form a head. Instead, they grow as a loose rosette of large, dark green leaves that have a slightly bitter taste.

Collard greens are a cool-season crop that is typically grown in the fall and winter months. They prefer well-drained soil that is rich in organic matter. Collard greens are a hardy plant that can tolerate temperatures as low as 20°F (-6°C), making them an ideal crop for colder climates.

When planting collard greens, it is important to avoid planting them near certain other plants. Some plants can negatively impact the growth and health of collard greens. For example, cabbage, kale, broccoli, cauliflower, and other members of the Brassicaceae family can attract pests and diseases that can harm collard greens.

On the other hand, there are some plants that make good companion plants for collard greens. These plants can help to repel pests and provide nutrients to the soil. Good companion plants for collard greens include mugwort, thyme, rosemary, oregano, marjoram, mint, catnip, southernwood, chamomile, garlic, potatoes, onions, hyssop, and dill.

Spacing

Collard greens require adequate spacing to allow for proper growth and air circulation. It is recommended to space them out about 18-24 inches apart.

Companion Planting

When it comes to companion planting with collard greens, it is important to avoid planting them with other members of the Brassicaceae family, such as broccoli, cauliflower, and cabbage. These plants can attract similar pests and diseases, which can harm the collard greens.

Common Pests and Diseases

Collard greens are susceptible to various pests and diseases, which can significantly affect their growth and yield. Here are some of the most common pests and diseases that collard greens may encounter:

Pests

Aphids are one of the most common pests that can infest collard greens. These small, soft-bodied insects feed on the plant’s sap, causing leaves to curl and yellow. Cabbage loopers are another common pest that can cause significant damage to collard greens. These caterpillars feed on the leaves, leaving behind large holes.

Cutworms are another pest that can cause damage to collard greens. These larvae of various moth species can cut through the plant’s stem, causing it to wilt and die. Flea beetles are also a common pest that can damage the leaves of collard greens. These small, black beetles feed on the leaves, leaving behind small holes.

Diseases

Collard greens are also susceptible to various diseases, which can cause significant damage to the plant. Black rot is a bacterial disease that can cause the leaves to wilt and turn yellow. The disease can spread quickly, causing the plant to die.

Clubroot is another disease that can affect collard greens. This fungal disease can cause the roots to become swollen and deformed, making it difficult for the plant to absorb nutrients. Downy mildew is another common disease that can affect collard greens. This fungal disease can cause the leaves to turn yellow and develop a fuzzy coating.

Harvesting and Using Collard Greens

Collard greens are a versatile and nutrient-rich vegetable that can be harvested and used in a variety of dishes. They are typically ready to harvest when the leaves are large and dark green, usually about 60-75 days after planting. It’s important to harvest the leaves before they become too tough or bitter.

To harvest collard greens, simply cut the leaves off the plant with a sharp knife or scissors, leaving the stem intact. You can harvest the outer leaves first, allowing the inner leaves to continue growing. Alternatively, you can harvest the entire plant at once by cutting it off at the base.

Once you’ve harvested your collard greens, there are many different ways to use them. Here are a few ideas:

1. Sautéed collard greens: Heat some oil in a pan and add chopped garlic and onion. Once they’re fragrant, add your collard greens and cook until they’re wilted and tender. Season with salt and pepper to taste.
2. Braised collard greens: Heat some oil in a pot and add chopped bacon or ham hock. Once they’re browned, add chopped onion and garlic and cook until they’re soft. Add your collard greens and enough chicken broth to cover them. Simmer until the greens are tender and the liquid has reduced.
3. Collard green wraps: Use collard greens as a healthy and low-carb alternative to tortillas. Simply blanch the leaves in boiling water for a few seconds to soften them, then fill with your favorite ingredients like hummus, roasted vegetables, or grilled chicken.

Incompatible Plants with Collard Greens

Collard greens are a nutritious and tasty vegetable that can be grown in a home garden. However, it is important to be aware of what not to plant with collard greens to avoid stunted growth, pest infestations, and diseases.

Members of the cabbage family, including cabbage, kale, broccoli, and cauliflower, should not be planted near collard greens. They attract similar pests and diseases, such as aphids, cabbage loopers, and clubroot. These pests and diseases can quickly spread and damage the entire crop.

Mint is another plant that should not be planted near collard greens. Mint has a tendency to spread rapidly and can easily take over a garden bed. It is also known to attract aphids, which can then spread to the collard greens.

Onions and garlic are also not good companion plants for collard greens. They release a strong odor that can attract pests and mask the scent of collard greens from beneficial insects.

Dill is a member of the same family as collard greens and can cross-pollinate with them. This can result in a strange taste in both plants. Dill also attracts carrot fly, which can damage collard greens and other plants in the same family.

Choosing the Right Variety of Collard Greens

When it comes to planting collard greens, choosing the right variety is crucial. Different varieties have different characteristics that make them more or less suitable for planting alongside other crops or in specific climate conditions.

One important factor to consider is bolt resistance. Some varieties, such as Champion and Vates, are known for their slow bolt rate, making them ideal for planting in warmer climates. On the other hand, Flash and Hybrid varieties tend to bolt quickly, so they may not be the best choice if you live in an area with hot summers.

Another consideration is the size of the plant. Morris Heading and Georgia Southern are both large varieties that can grow up to 3 feet tall, making them a good choice if you have plenty of space in your garden. However, if you have limited space, you may want to consider planting a smaller variety like Champion or Vates.

It’s also worth noting that some varieties have a sweeter flavor than others. If you prefer a sweeter taste, you may want to try Morris Heading or Georgia Southern. However, if you prefer a more bitter taste, Vates or Champion may be a better choice.
