Kale Companion Plants: Growing Guide

The Importance of Companion Planting for Kale

Growing kale can be a rewarding experience, but it also requires proper care and attention. One way to ensure your kale thrives is by choosing the right companion plants. Companion planting refers to growing different plants together that benefit each other in some way. In this article, we'll explore the best companion plants for kale and how they can improve your garden.

The Best Companion Plants for Kale

1. Lettuce

Lettuce is a great companion plant for kale because it grows quickly and doesn't take up much space. It can be planted alongside kale and harvested before the kale reaches maturity. Additionally, lettuce has shallow roots, which won't compete with kale's deep roots.

How to Plant:

Plant lettuce seeds 6 inches apart alongside kale rows. Ensure they have plenty of sunlight and well-draining soil.

2. Beans

Beans are legumes that fix nitrogen in the soil, making them an excellent companion to kale. Nitrogen is essential for plant growth, and kale needs a lot of it. By planting beans near kale, the beans will release nitrogen into the soil, benefiting both plants.

How to Plant:

Plant pole beans or bush beans 12 inches apart in rows between your kale plants. Ensure they get plenty of sunlight and water.

3. Carrots

Carrots are root vegetables that grow well alongside kale. They don't take up much space and can be harvested before the kale reaches maturity. Carrots also help break up the soil, making it easier for kale's deep roots to absorb nutrients.

How to Plant:

Plant carrot seeds between your kale rows, spacing them 2 inches apart. Ensure they have plenty of sunlight and well-draining soil.

4. Cabbage

Cabbage is a close relative of kale and makes an excellent companion plant. Both plants have similar nutrient requirements and growing conditions. Additionally, cabbage can help repel pests that may damage kale.

How to Plant:

Plant cabbage seedlings 18 inches apart in rows between your kale plants. Ensure they get plenty of sunlight and water.

5. Herbs

Herbs like dill, thyme, and chamomile can be grown alongside kale to improve its flavor and protect it from pests. Dill can attract beneficial insects like ladybugs, which eat aphids that may harm kale. Thyme can help repel cabbage moths and other pests, while chamomile can improve the flavor of kale when used in cooking.

How to Plant:

Plant herbs in between your kale rows or in small clusters throughout your garden. Ensure they get plenty of sunlight and well-draining soil.

Other Tips for Growing Kale

1. Provide Adequate Water

Kale needs plenty of water to grow properly. Ensure your plants receive at least an inch of water per week, either through rainfall or irrigation. Avoid overwatering, which can lead to root rot and other problems.

2. Mulch Your Plants

Mulching your kale plants can help retain moisture in the soil and prevent weeds from growing. Apply a layer of organic mulch around your plants, ensuring it doesn't touch the stems.

3. Protect Your Plants from Pests

Pests like aphids, cabbage worms, and flea beetles can damage your kale plants. Use organic pest control methods like releasing ladybugs or spraying with neem oil to protect your plants.

4. Harvest Properly

Harvest your kale leaves from the bottom up, taking only a few leaves from each plant at a time. Avoid harvesting all the leaves at once, as this can stress the plant and reduce its productivity.



Companion planting is an excellent way to improve the health and productivity of your kale plants. By choosing the right companion plants, you can create a thriving garden that produces delicious and nutritious food. Remember to provide adequate water, mulch your plants, and protect them from pests. With these tips, you'll be on your way to growing healthy and delicious kale.

It's generally not recommended to plant kale and other brassicas like broccoli and cauliflower together because they are susceptible to similar pests and diseases.

3. How often should I fertilize my kale plants?

Kale plants don't need frequent fertilization, as they are heavy feeders and can absorb nutrients from the soil. Apply a balanced fertilizer before planting and again halfway through the growing season.

4. How do I know when to harvest my kale?

Harvest your kale leaves from the bottom up, taking only a few leaves from each plant at a time. Mature kale leaves can be harvested when they are around 8-10 inches long.

5. Can I freeze kale for later use?

Yes, kale can be frozen for later use. Blanch the leaves in boiling water for 2-3 minutes, then plunge them into ice water. Drain and pack the leaves into freezer bags or containers. They will keep for up to 6 months in the freezer.
