Companion planting is a fascinating and beneficial gardening technique that involves pairing plants together to enhance their growth, flavor, and resilience. For kale enthusiasts looking to cultivate a thriving garden, understanding which plants to grow alongside this nutrient-dense leafy green can make all the difference. In this article, we’ll explore the intricacies of companion planting for kale, including the benefits, ideal partners, practical tips, and answers to common questions.
What is Companion Planting?
Companion planting is the practice of growing different plants in proximity for mutual benefits. These benefits can include:
- Pest Control: Certain plants can repel pests or attract beneficial insects that prey on harmful ones.
- Improved Growth: Some plants can enhance each other’s growth potential by sharing nutrients or providing shade.
- Soil Enhancement: Some plants improve soil quality and nutrient availability, benefiting neighboring plants.
- Flavor Enhancement: Certain combinations can enhance the taste of crops grown in proximity.
Why Kale?
Kale (Brassica oleracea var. sabellica) is an incredibly popular and nutritious leafy green belonging to the brassica family, which includes broccoli, cauliflower, and Brussels sprouts. Kale is valued for its hardy growth, robust flavor, and impressive nutritional profile, including high levels of vitamins A, C, K, and various antioxidants.
Given its importance and popularity, understanding what plants make great companions for kale can encourage more productive and healthier harvests while also better utilizing garden space.
Benefits of Companion Planting for Kale
1. Pest Management
Pests like aphids, cabbage worms, and slugs can wreak havoc on kale plants. Companion plants such as garlic, onions, and herbs like rosemary can deter these pests through their strong scents. By planting these companions nearby, gardeners can reduce pest pressure on their kale crops.
2. Nutrient Sharing
Kale benefits from nutrient-sharing partnerships. For example, legumes such as peas and beans have a unique ability to fix nitrogen in the soil—an essential nutrient for kale growth. When planted in succession or in close proximity, these plants can contribute to richer soil and higher yields.
3. Improved Flavor
Certain herbs and flowers can enhance the flavor characteristics of kale. For example, neighboring aromatic herbs such as dill and basil can impart a delightful complexity to the greens, making them more flavorful when harvested.
4. Microclimate Creation
Tall plants, like corn or sunflowers, can provide shade that helps protect kale from extreme heat. By strategically placing taller plants around kale, gardeners can create more favorable microclimates, promoting better growth and resilience.
5. Soil Support
Certain companion plants help improve soil structure and health. For example, growing clover alongside kale can increase soil aeration and enhance moisture retention, making it easier for kale roots to thrive.
Ideal Companion Plants for Kale
Now that we’ve explored the benefits of companion planting, let’s delve into the specific plants that make excellent companions for kale.
1. Legumes (Peas and Beans)
Legumes, particularly peas and bush beans, are stellar companions for kale. They have the ability to fix atmospheric nitrogen into the soil, enriching it for the nutrient-hungry kale.
- Planting Tip: Plant peas in early spring as kale begins its growing season. Beans can follow once the soil has warmed up in late spring.
2. Herbs (Dill and Rosemary)
Both dill and rosemary serve dual purposes in the garden—flavoring your dishes and repelling pests. Dill attracts beneficial insects like ladybugs and lacewings, which prey on aphids.
- Planting Tip: Space these herbs at the edge of your kale bed or intermixed between kale rows.
3. Alliums (Garlic and Onions)
Alliums like garlic and onions emit strong fragrances that deter several common pests that target kale. Moreover, they are relatively low-maintenance and can grow well alongside kale’s leafy growth.
- Planting Tip: Plant garlic in the fall just before the kale starts to overwinter, using the space around kale to maximize area efficiency.
4. Nasturtiums
Nasturtiums are not just beautiful; they also act as a trap crop for aphids, drawing them away from kale. The leaves and flowers of nasturtiums are edible, adding a spicy zing to salads, which can complement your kale.
- Planting Tip: Sow nasturtium seeds in the same bed as your kale, or around the borders for added pest protection.
5. Marigolds
These bright, cheerful flowers are more than just eye candy; they help suppress nematodes and attract beneficial insects. Marigolds can provide significant pest control benefits, serving as a beautiful companion to your kale beds.
- Planting Tip: Interplant marigolds among kale plants for effective pest management.
6. Spinach
Spinach and kale share similar growing conditions and complement each other well in terms of nutrient requirements. Furthermore, the spinach can provide ground cover that helps retain soil moisture for both plants.
- Planting Tip: Plant spinach alongside kale, but consider staggering the harvest times to minimize competition.
7. Carrots
Carrots and kale grow well together since they occupy different soil layers—carrots grow deep while kale extends its roots higher up. Additionally, the scent of the carrots can act as a natural deterrent for certain pests.
- Planting Tip: Sow carrot seeds directly into the kale bed about a month after planting the kale to ensure staggered harvesting.
8. Cabbage Family Members
Other members of the brassica family like broccoli and Brussels sprouts can be planted alongside kale, given that they share similar nutrient and environmental requirements.
- Planting Tip: Keep a rotation plan to minimize pest attraction to all brassicas in the same area.
Practical Tips for Companion Planting with Kale
1. Understanding Your Space
Start by sketching your garden layout. Consider which plants are taller and which will remain shorter, ensuring sufficient light reaches all plants. Be mindful of growth habits and spacing to prevent overcrowding and competition for nutrients.
2. Planning for Pests
Do your research on local pests and consider what plants work best together to manage those pests effectively. For instance, if aphids are a significant issue, plant Nasturtiums or dill.
3. Succession Planting
Utilizing succession planting can maximize your growing space. After harvesting kale (or other brassicas), replant with legumes or another compatible crop to enrich the soil.
4. Crop Rotation
To avoid pest and disease buildup, practice crop rotation. Make sure to alternate your brassica family plants with non-related plants in following seasons.
5. Mulching
Applying mulch around your plants can help retain moisture and keep the soil temperature stable, benefiting kale and its companions alike.
6. Monitor and Adapt
Keep an eye on the interactions within your garden. Be prepared to adapt your planting strategies based on what you observe. Some combinations may work better than others, influenced by local climate, soil type, and plant health.
Common Questions about Companion Planting for Kale
1. Can you plant kale with tomatoes?
Kale and tomatoes may not be the best companions. Tomatoes can attract pests like aphids that also affect kale, plus they have different water requirements. Instead, opt for plants that are known to repel pests or share similar water needs.
2. How far apart should I plant my kale and its companions?
The spacing largely depends on the specific plants involved. Kale typically requires around 12-18 inches of space between plants. Companion plants should be spaced according to their individual needs while ensuring they don’t overshadow or overcrowd the kale.
3. What should I do if my companion plants are not thriving?
Be mindful of environmental conditions. Check for factors such as insufficient sunlight, competition for nutrients, or pest issues. Sometimes, relocating plants or enhancing soil quality can help.
