Tips for Growing Kale Indoors and Out


Growing kale is a great way to add fresh and nutritious greens to your diet. Whether you have a spacious garden or limited outdoor space, or even if you prefer to grow your kale indoors, there are several tips and tricks that can help you achieve a successful harvest. In this article, we will explore the best practices for growing kale, both indoors and outdoors.

Choosing the Right Variety

There are different varieties of kale available, each with their own unique characteristics. When choosing a variety, consider factors such as taste, texture, and growth habit. Some popular kale varieties include curly kale, Lacinato kale, and Red Russian kale. Research the different varieties to find the one that suits your preferences and growing conditions.

Indoor Growing Tips

1. Provide Adequate Lighting

When growing kale indoors, it is crucial to provide sufficient lighting. Kale requires at least 6-8 hours of sunlight per day. If you don’t have access to natural sunlight, consider using grow lights or fluorescent lights to provide the necessary light intensity.

2. Choose the Right Container

Select a container that is at least 12 inches deep to accommodate the kale’s root system. Ensure the container has drainage holes to prevent waterlogging. Use a well-draining potting mix to provide the necessary nutrients and aeration for the plants.

3. Maintain Optimal Temperature and Humidity

Kale thrives in cooler temperatures, ideally between 60-70°F (15-21°C). Keep the humidity levels around 50-70% to prevent the leaves from drying out. Use a humidifier or mist the leaves regularly to maintain the required moisture.

4. Watering and Fertilizing

Water the kale plants regularly, keeping the soil consistently moist but not waterlogged. Avoid overwatering as it can lead to root rot. Fertilize the plants every 2-3 weeks with a balanced organic fertilizer to promote healthy growth and abundant foliage.

Outdoor Growing Tips

1. Choose the Right Location

Select a sunny spot in your garden that receives at least 6 hours of direct sunlight daily. Kale can tolerate partial shade, but it thrives in full sun. Ensure the soil is well-draining and rich in organic matter.

2. Prepare the Soil

Before planting kale outdoors, prepare the soil by removing any weeds and adding compost or well-rotted manure. Kale prefers slightly acidic soil with a pH level between 6.0 and 7.5. Test the soil and make the necessary amendments to create an optimal growing environment.

3. Planting and Spacing

Sow the kale seeds directly into the prepared soil, or transplant seedlings if you started them indoors. Space the plants about 12-18 inches apart to provide adequate room for growth. Water the plants immediately after planting to help them settle in.

4. Mulching and Maintenance

Apply a layer of organic mulch around the base of the plants to conserve moisture and suppress weed growth. Water the plants regularly, especially during dry spells. Monitor for pests and diseases, and take appropriate measures to control them.


Growing kale can be a rewarding experience, whether you choose to grow it indoors or outdoors. By following these tips, you can ensure healthy and thriving kale plants that will provide you with a bountiful harvest of nutritious greens. Experiment with different varieties and techniques to find what works best for you. Happy growing!
