Kale is one of the hardiest and most versatile leafy greens you can grow in your garden or on your deck. It thrives in a wide range of climates and can be cultivated almost year-round in many regions. In this blog, we’ll explore how to grow kale in different USDA hardiness zones and whether using fabric pots from 247Garden is a good choice for growing this nutritious green.

Growing Kale in Different Zones

Zone 3-4 (Cold Regions)

  • Growing Season: Late spring through early fall.
  • Challenges: Frost is common in these zones, so start your seeds indoors 4-6 weeks before the last frost date.
  • Winter Care: Kale can survive light frosts and even become sweeter, but if a hard frost is expected, consider covering your plants or bringing them indoors if they're in grow bags.

Zone 5-6 (Cool to Mild Regions)
Kale is a cool-season crop that thrives in temperatures between 55-75°F. In Zone 5b, you can start seeds indoors 4-6 weeks before the last frost date, then transplant them outside when the soil is workable. Kale will grow well through the spring and summer, but it really shines in the fall. The cooler temperatures of autumn enhance the flavor and sweetness of the leaves. To ensure a continuous harvest, sow seeds every few weeks during the growing season.

Zone 8 and Above (Warmer Regions)
In warmer zones like Zone 8, kale can be grown almost continuously. The main challenge is protecting the plants from the intense heat of summer. Plant kale in the fall for a winter crop, as it grows best in cooler weather. If you have particularly hot summers, a shade cloth can help protect your kale from the scorching sun. Kale can bolt quickly in these regions if temperatures rise too high, so keep a close eye on your plants during heat waves.

Can You Grow Kale in Fabric Pots?

Absolutely! Fabric pots, like the ones from 247Garden, are an excellent choice for growing kale. Here's why:

  1. Enhanced Root Health: Fabric pots offer excellent aeration and drainage, which help prevent root rot and other moisture-related issues. Kale roots stay healthier in these containers because they have room to breathe.
  2. Temperature Regulation: The breathable fabric helps regulate soil temperature, keeping the roots cooler in the summer and providing a bit of insulation during colder months. This makes it easier to grow kale in zones with varying climates.
  3. Mobility: Fabric pots are lightweight and portable, allowing you to move your plants to different locations based on sunlight or weather conditions. If a frost is coming, you can easily move your kale to a sheltered area.
  4. Versatility: Fabric pots come in different sizes, so you can choose the best one depending on how much space you have on your deck or in your garden. For kale, a 5 to 10-gallon fabric pot should provide plenty of space for the roots to grow and the plant to flourish.

Tips for Growing Kale in Fabric Pots

  • Choose the Right Size: For a single kale plant, a 5-gallon fabric pot is usually sufficient. If you plan on growing multiple plants, consider larger pots or spacing several smaller ones.
  • Use Good Quality Soil: Kale is a heavy feeder, so it thrives in nutrient-rich soil. Mix in compost or slow-release fertilizers to ensure the plants get the nutrients they need throughout the growing season.
  • Consistent Watering: Keep the soil evenly moist, but not waterlogged. Fabric pots can dry out faster than traditional pots, so you might need to water more frequently during hot weather.
  • Fertilize Regularly: Since kale is a heavy feeder, it benefits from regular feeding with a balanced fertilizer. This will help ensure that the leaves grow large and flavorful.
  • Pest Management: Watch out for common kale pests like aphids and cabbage worms. Growing kale in fabric pots makes it easier to manage these pests since you can move the plants or cover them if needed.

Kale Varieties to Try in Fabric Pots

  • Lacinato (Dinosaur Kale): Known for its dark, bumpy leaves, Lacinato kale is a favorite for smoothies and salads.
  • Red Russian Kale: This variety has tender leaves with a slightly sweet flavor, perfect for raw dishes.
  • Curly Kale: The classic variety, great for making kale chips or adding to soups and stews.

Best Size Grow Bags for Growing Kale

  • 5-Gallon Grow Bag: Suitable for growing a single kale plant. It provides enough root space to support good leaf production. Can consider the short and wide version 5-gallon fabric pots.
  • 7-Gallon Grow Bag: Ideal for growing multiple kale plants (2-3 plants), ensuring they have adequate space to develop. Can consider the short and wide version 7-gallon fabric pots.
  • 10-Gallon Grow Bag: Best for those looking to grow more plants in a compact space. This size allows you to grow 4-5 kale plants, which can be very productive for a small family. Can consider the short and wide version 10-gallon fabric pots.
  • 15-Gallon Grow Bag: Great for larger-scale kale growing or if you want to grow kale alongside other leafy greens in the same container. This is particularly helpful if you're looking to harvest consistently. Can consider the short and wide version 15-gallon fabric pots.

For best results, use 247Garden's fabric pots in either black or tan, as these offer excellent aeration for the roots, leading to healthier, more productive plants.
