Understanding Companion Planting
Companion planting is a time-honored gardening technique that puts the concept of plant community to practical use.
It involves strategically growing different types of plants together, capitalizing on their naturally occurring properties to make a garden thrive.
Some plants exude chemicals from roots or aerial parts that could either attract or repel pests and enhance the growth and yield of nearby plants.
This practice has diverse implications such as pest control, pollinator attraction, maximizing the use of space, promoting healthy soil conditions, and improving crop productivity.
For instance, certain herbs can improve the flavor profile of kale while others can deter harmful insects.
Flowers like marigolds not only beautify your kale patch but also serve as powerful insect repellents with their distinct aroma.
Understanding companion planting plays a pivotal role in establishing a self-sustaining ecosystem within your vegetable garden!
Benefits of Companion Planting with Kale
Companion planting reaps several advantages in cultivating kale, a versatile superfood.
It’s a holistic gardening strategy that enhances the growth of your leafy greens while promoting an overall healthier garden ecosystem.
Companion plants play crucial roles: they allure beneficial pollinators and insects which contribute to plant reproduction and predate on harmful pests.
In addition to attracting helpful insects, some companion crops inhibit destructive creatures from infesting your kale plants.
This natural pest control reduces reliance on chemical pesticides, contributing to safer food consumption and healthier soil composition over time.
Herbs like cilantro fend off unwanted aphids while marigolds deter cabbage loopers – two common threats to kale plants.
Meanwhile, certain companions enrich the soil with much-needed nutrients that boost kale’s growth and productivity.
For instance, legumes such as peas or beans restore nitrogen levels in the ground – an essential nutrient for thriving cruciferous vegetables like kale.
Similarly, cover crops like buckwheat help maintain soil moisture and suppress weed growth around your precious frizzy varieties, ensuring that they are given maximum space and nutrients for optimal development.

This means that by growing cucumbers near your kale plants, you can naturally protect them from pest infestations without relying on chemical pesticides.
Cucumbers have another amazing benefit, they actually improve the soil when they are planted close to kale because of their nitrogen-fixing abilities.

Detailed Guide on Growing Kale Plants
- Choose a sunny location for your kale plants, as they thrive in full sun but can tolerate some shade.
- Prepare the soil by adding compost or organic matter to improve its fertility and drainage.
- Sow kale seeds directly into the garden or start them indoors 4 to 6 weeks before the last frost date. Plant them about ½ inch deep and space them 12 to 18 inches apart.
- Keep the soil consistently moist but not waterlogged, as kale prefers evenly moist conditions.
- Mulch around the base of the plants to help retain moisture and suppress weeds.
- Fertilize kale plants regularly with a nitrogen-rich fertilizer or use companion plants like legumes for natural nitrogen fixation in the soil.
- Monitor for pests such as aphids, flea beetles, and cabbage loopers. Use organic pest control methods like introducing beneficial predators or using homemade insecticidal soap if necessary.
- Harvest the leaves when they get around 8 to 10 inches long. You’ll want to pick the outer leaves first and let the inner leaves continue growing for you next round of harvesting.
- To extend the harvest season, you can harvest kale in a cut-and-come-again method by cutting off individual leaves instead of harvesting entire plants.
Harvesting Tips for Kale
Harvesting kale can be rewarding because you get to finally enjoy the delicious and nutrient-packed leaves from your garden.
Here are a few suggestions, for selecting the kale leaves:
- Begin harvesting when the leaves have fully matured allowing them to grow to 6 inches in length before you start cutting them. This is usually around 55-75 days after planting, depending on the variety.
- Pick outer leaves first: When harvesting kale, focus on picking the outer leaves first. These leaves are older and ready for harvest, while the inner leaves continue to grow.
- Use sharp scissors or shears: Go in with precision, snip those leaves right at the base of the stem, and voilà! You’ll steer clear of any unwanted plant damage.
- Leave some leaves behind: While it may be tempting to harvest all the kale at once, it’s best to leave a few inner leaves intact. This allows them to continue growing and provides a continuous supply of fresh kale throughout the season.
- Regularly remove yellowed or damaged leaves: As your kale plants age, some of the lower leaves may turn yellow or become damaged. Removing these leaves not only improves aesthetics but also promotes healthier growth by redirecting nutrients to younger foliage.
- Harvest in moderation: Instead of completely depleting your kale plant, practice moderation when harvesting. Aim to take no more than one-third of the plant’s foliage at each harvest session, allowing it time to recover and continue producing.
- Harvest throughout the season: Kale is a cool-season crop that can tolerate light frosts and even tastes sweeter after exposure to cold temperatures. Continuously harvest throughout the season rather than waiting until all mature leaves are present for large-scale harvesting.

Tomatoes are not recommended as companion plants for kale due to their potential to compete with kale for nutrients.
Both tomatoes and kale belong to the nightshade family, and planting them together can lead to overcrowding and stunted growth.
For the growth of both crops it is advisable to allocate sections in the garden or plant them at a sufficient distance from each other.
By avoiding planting tomatoes alongside your kale, you can create a more balanced growing environment and maximize the health and productivity of both plants.
Planting different types of crops together is a decision that can benefit any gardener. It can improve their garden’s yield and also help in establishing a self-sustaining ecosystem.
