Whether you’re an experienced gardener or just starting out, this guide will provide you with everything you need to know to grow healthy and delicious cabbage in your garden. Let’s dive in!

How Much Space Does Cabbage Need to Grow?

Cabbage is a cool-season crop that can grow in a wide range of climates. When it comes to spacing, cabbage plants need enough room to grow, develop, and mature. Here are some guidelines on how much space cabbage needs to grow:

  1. Spacing between plants: Cabbage plants should be spaced about 12-18 inches apart in rows that are 2-3 feet apart. This spacing allows for good air circulation, which helps prevent disease and pests.
  2. Container size: If you’re growing cabbage in containers, use pots that are at least 12 inches deep and wide, and make sure to plant only one cabbage plant per container.
  3. Soil preparation: Cabbage needs well-draining soil that is rich in organic matter. Prepare the soil by adding compost, aged manure, or other organic material to improve soil structure and fertility.
  4. Sun exposure: Cabbage needs full sun exposure for at least 6 hours a day to grow properly.

By providing your cabbage plants with adequate spacing, soil preparation, and sunlight, you can ensure that they have enough space to grow and produce healthy, delicious heads of cabbage.

What Happens if You Plant Cabbage Too Close Together?

Planting cabbage too close together can have several negative effects on the growth and health of the plants. Here are some of the potential problems that can arise if you plant cabbage too close together:

  1. Stunted growth: When cabbage plants are planted too close together, they may not have enough space to grow and develop properly. This can lead to stunted growth, which can result in smaller heads of cabbage.
  2. Increased competition for nutrients: Cabbage plants that are crowded may have to compete with each other for nutrients in the soil. This can lead to nutrient deficiencies, which can stunt growth and reduce the overall health of the plants.
  3. Increased risk of disease: Cabbage plants that are grown too close together can be more susceptible to diseases such as clubroot, which can spread quickly in crowded conditions.
  4. Increased risk of pest infestations: When cabbage plants are crowded, pests such as aphids and cabbage loopers may be more attracted to them, leading to infestations.

In summary, planting cabbage too close together can lead to stunted growth, increased competition for nutrients, and increased risk of disease and pest infestations. To avoid these problems, it’s important to provide enough spacing between cabbage plants to ensure their proper growth and health.

What Happens if You Plant Cabbage Too Far Apart?

Planting cabbage too far apart can also have negative effects on the growth and health of the plants. Here are some potential problems that can arise if you plant cabbage too far apart:

  1. Wasted space: If you plant cabbage too far apart, you may be wasting valuable gardening space in your garden bed or plot.
  2. Increased exposure to weeds: When cabbage plants are spaced too far apart, there is more exposed soil between them, which can lead to an increase in weed growth. Weeds can compete with cabbage for water and nutrients, which can reduce the overall health and productivity of the plants.
  3. Increased water usage: When cabbage plants are spaced too far apart, they may not be able to shade each other, which can lead to increased water usage as the plants try to stay hydrated.
  4. Sunscald: If cabbage plants are spaced too far apart, the heads of cabbage may be more exposed to direct sunlight, which can lead to sunscald, a condition where the outer leaves of the cabbage head become discolored and dry.

In summary, planting cabbage too far apart can lead to wasted space, increased exposure to weeds, increased water usage, and sunscald. To ensure optimal growth and health, it’s important to provide cabbage plants with adequate spacing, as described earlier.

How to Figure Out Spacing Requirement of Different Cabbage Varieties

The spacing requirements for different cabbage varieties may vary depending on the size of the mature heads and the growth habits of the specific cultivar. Here are some steps to figure out the spacing requirements for different cabbage varieties:

  1. Determine the mature head size: Find out the average size of the mature head for the cabbage variety you plan to grow. This information can typically be found on the seed packet or in a gardening book or online resource.
  2. Calculate the spacing needed: To determine the spacing requirements, you can use a general rule of thumb that recommends planting cabbage at a distance that is equal to or slightly greater than the mature head size. For example, if the mature head size is 8 inches in diameter, plant the cabbage at least 8-10 inches apart.
  3. Adjust for growth habits: Some cabbage varieties have more compact growth habits, while others may have a more sprawling growth pattern. If you’re growing a variety that tends to grow larger or spread out more, you may need to adjust your spacing accordingly.
  4. Consider companion planting: Cabbage can benefit from companion planting with plants that attract beneficial insects or help repel pests. If you plan to companion plant, you may need to adjust your spacing to accommodate the additional plants.

In summary, to figure out the spacing requirements for different cabbage varieties, determine the mature head size, calculate the spacing needed based on that size, adjust for growth habits, and consider companion planting. By providing your cabbage plants with the right amount of spacing, you can help ensure healthy growth and productive harvests.

Examples of Spacing Requirements for Different Cabbage Varieties

Here are some examples of spacing requirements for different cabbage varieties:

  1. Early Jersey Wakefield: This variety has small, pointed heads that are about 2-3 pounds in size. It is recommended to plant them about 12-18 inches apart.
  2. Copenhagen Market: This variety has large, round heads that are about 6-8 pounds in size. It is recommended to plant them about 18-24 inches apart.
  3. Napa cabbage: This variety has long, cylindrical heads that are about 2-3 pounds in size. It is recommended to plant them about 12-18 inches apart.
  4. Savoy cabbage: This variety has crinkled, dark green leaves and heads that are about 3-4 pounds in size. It is recommended to plant them about 18-24 inches apart.
  5. Red cabbage: This variety has deep purple, round heads that are about 4-5 pounds in size. It is recommended to plant them about 18-24 inches apart.

Remember, these are just general recommendations and the spacing requirements may vary depending on the specific cultivar and growing conditions. Always refer to the seed packet or gardening resources for specific instructions on how to space and care for your cabbage plants.

What to Avoid Planting Near Cabbage

Cabbage is a member of the brassica family, and there are certain plants that should be avoided when planting cabbage to prevent pest and disease issues. Here are some plants to avoid planting near cabbage:

  1. Other brassicas: Cabbage should not be planted near other brassicas, such as broccoli, cauliflower, kale, or Brussels sprouts. This is because they are all susceptible to the same pests and diseases, and planting them together can lead to increased infestations and reduced yields.
  2. Tomatoes: Tomatoes should also be avoided near cabbage, as they attract the same pests and diseases. Additionally, tomatoes have a high demand for nutrients and may compete with cabbage for soil nutrients.
  3. Strawberries: Strawberries may attract slugs and snails, which can also feed on cabbage leaves. Planting them together may increase the risk of slug and snail infestations.
  4. Pole beans: Pole beans may attract aphids, which can also feed on cabbage leaves. Planting them together may increase the risk of aphid infestations.
  5. Plants with high nitrogen demands: Cabbage does not require a lot of nitrogen, and planting it near plants with high nitrogen demands, such as corn or lettuce, may lead to nutrient deficiencies.

In summary, to avoid pest and disease issues, it’s best to avoid planting cabbage near other brassicas, tomatoes, strawberries, pole beans, and plants with high nitrogen demands. Instead, consider planting cabbage near plants that attract beneficial insects, such as marigolds, or plants that can repel pests, such as onions or garlic.
