Understanding the Basics of Kale Plant Spacing

Importance of Proper Spacing

Proper spacing is important for the healthy growth of kale plants. If you plant kale seeds too close together, the plants will compete for nutrients, water, and sunlight.

This can result in stunted growth, poor-quality leaves, and lower yields.

On the other hand, if you space your kale plants too far apart, you will waste valuable garden space and reduce your overall yield.

Ideal Spacing for Kale

The ideal spacing for kale plants depends on the variety of kale you are growing and your planting method.

For full-sized bunching kale, you should space each plant 18 to 24 inches apart from one another.

This spacing will allow the plant not to feel crowded when it reaches mature heights of one to three feet.

For baby greens, you can plant seeds closer together, about 1/2 to one inch apart.

When planting kale in raised beds and in rows, you can space the plants closer together. For full-sized kale, space each plant 12 to 18 inches apart.

In containers, space each plant about 6 inches apart for a 3-gallon container.

Secrets to a Perfect Crop

If you want to grow a perfect crop of kale, there are a few secrets you should know.

Soil Preparation

Before planting kale, it's important to prepare the soil properly. Kale prefers well-draining soil that is rich in nutrients.

You can achieve this by adding compost or aged manure to the soil. If your soil is too acidic, add some lime to bring the pH level up to around 6.5 to 7.0.

Watering and Sunlight Requirements

Kale needs plenty of water to grow properly, especially during hot and dry weather.

Watering Kale at the garden

Make sure to water your plants deeply and regularly, but avoid overwatering as this can lead to root rot.

Like most leafy vegetables, kale also needs plenty of sunlight to grow, so make sure to plant it in a spot that gets at least 6 hours of direct sunlight per day.

Pest and Disease Management

Kale is susceptible to a few common pests and diseases, including aphids, cabbage worms, and powdery mildew.

To prevent these problems, make sure to keep your plants healthy by providing them with plenty of water and nutrients.

You can also use organic pest control methods, such as neem oil or insecticidal soap, to keep pests at bay.

Companion Planting

When planting kale, it's important to consider companion planting. This is the practice of planting different crops together to improve growth and health.

Some good companion plants for kale include:

  • Lettuce: These two plants have similar growing requirements and can be planted together to maximize space and yield.
  • Beans: Beans add nitrogen to the soil, which is beneficial for kale growth.
  • Herbs: Herbs like thyme and rosemary can help repel pests that may damage kale plants.


Kale is a heavy feeder and can deplete the soil of nutrients. To avoid this, it's important to rotate your kale crops.

This means planting kale in a different location each year to allow the soil to rest and replenish.

When rotating your kale crops, it's important to avoid planting them in the same location as other members of the brassica family, such as broccoli or cauliflower.

This can increase the risk of pests and disease.

Succession Planting

Succession planting is the practice of planting crops at different times to ensure a continuous harvest.

Common Mistakes and How to Avoid Them


One common mistake when planting kale is overcrowding.

It might be tempting to plant as many kale plants as possible to maximize your harvest, but this can actually lead to stunted growth and poor yields.

When kale plants are too close together, they compete for resources like water, nutrients, and sunlight. This can result in smaller leaves and a weaker plant.

To avoid overcrowding, make sure to space your kale plants properly.

Inadequate Watering

Another mistake that can lead to poor kale growth is inadequate watering.

Kale plants need consistent moisture to grow properly, especially during hot and dry weather.

Watering Kale in the garden

If your kale plants are not getting enough water, they may wilt and become stressed, which can lead to stunted growth or even death.

To avoid inadequate watering, make sure to water your kale plants deeply and consistently.

Aim to give your plants at least one inch of water per week, either through rainfall or irrigation.

You can also add a layer of mulch around your plants to help retain moisture in the soil.

Ignoring Soil Health

Finally, ignoring soil health is another mistake that can lead to poor kale growth.

Kale plants require nutrient-rich soil to grow properly, and if your soil is depleted or lacking in key nutrients, your plants may struggle to grow and produce.

Soil preparation for garden

To avoid ignoring soil health, make sure to test your soil regularly and amend it as needed.

Adding organic matter like compost or aged manure can help improve soil fertility and structure.

Additionally, make sure to rotate your kale plants each year to prevent soil-borne diseases and pests from building up in the soil.

Where to Grow Kale in Limited Space

If you have limited space, you can still grow kale! Kale is a great crop for small gardens, patios, balconies, and even indoors.

Here are some tips on where to grow kale in limited space:


Kale can be easily grown in containers, which is great for those with limited space. You can grow kale in pots, raised beds, or even hanging baskets.

Kale can also be grown indoors, which is perfect for those who don't have access to outdoor space or who live in apartments.

You can grow kale in a sunny window or under grow lights.

Wrap Up

Planting kale with proper spacing is crucial for a successful harvest.

Overcrowding kale plants can lead to stunted growth, poor air circulation, and an increased risk of disease and pests.

On the other hand, under-planting can result in wasted space and reduced yields.

Remember to consider the size of the kale variety you are planting, as well as your desired harvest. For baby kale, you can plant the seeds closer together, while microgreens require even less spacing.

Be sure to provide your kale plants with adequate nutrients, water, and sunlight to promote healthy growth.
