Part I: Planting Kale in August

  1. Ideal Planting Time: August is an ideal time to plant kale, as it prefers cooler temperatures and can withstand light frosts. Aim for soil temperatures between 60°F to 75°F (15°C to 24°C).
  2. Location and Soil: Choose a sunny or partially shaded spot in your garden with well-draining, fertile soil. Kale thrives in soil enriched with compost or well-rotted manure.
  3. Kale Varieties: Select kale varieties suitable for late planting and quick maturity. Look for options like ‘Curly Kale,’ ‘Lacinato (Dinosaur) Kale,’ or ‘Red Russian Kale.’
  4. Sowing Seeds: Sow kale seeds directly into the prepared soil, about 1/4 to 1/2 inch deep. Space the seeds 12 to 18 inches apart to give the plants ample room to grow.
  5. Watering and Moisture: Keep the soil consistently moist during germination and throughout the growing season. Adequate moisture is essential for healthy kale development.
  6. Thinning Seedlings: Once the kale seedlings have grown a few true leaves, thin them out to maintain proper spacing and promote robust growth.

Part II: Nurturing Kale Growth

  1. Mulching Benefits: Apply a layer of organic mulch around the kale plants to retain soil moisture, regulate temperature, and suppress weed growth.
  2. Protection from Heat: Provide some shade or use shade cloth during hot spells to prevent kale leaves from becoming bitter and tough.
  3. Feeding Kale: Kale is a moderate feeder, and a balanced fertilizer application can enhance leaf production and overall plant health.
  4. Pest and Disease Management: Keep an eye out for common pests like aphids and cabbage worms. Use natural remedies or introduce beneficial insects to control pest populations.
  5. Cold Tolerance: Kale is known for its cold-hardiness and often becomes sweeter after exposure to frost, making it a perfect late-season crop.

Part III: The Harvest and Beyond

  1. Harvesting Kale: Begin harvesting kale leaves when they reach a usable size, typically 8 to 10 inches long. Cut the outer leaves, allowing the inner ones to continue growing.
  2. Culinary Delights: Embrace the versatility of kale by using it in salads, smoothies, sautés, and even as crispy kale chips for a healthy snack.
  3. Health Benefits: Kale is a nutritional powerhouse, packed with vitamins A, C, and K, as well as minerals and antioxidants that support overall well-being.


Planting kale in August offers a delightful opportunity to cultivate a garden of thriving greens that nourish both body and soul. With proper care and attention, you can harvest a bounty of nutrient-rich kale leaves that will elevate your culinary creations and promote a healthy lifestyle. So, embrace the joy of gardening and sow the seeds of vibrant kale greens, bringing a taste of late-summer nourishment right to your table.
