Kale, a nutritional powerhouse, is often associated with cooler climates. But what if you crave that leafy green goodness even during the scorching summer months? Fear not, fellow gardeners! With a few clever strategies, you can successfully grow kale in hot weather and enjoy its vibrant flavor year-round.
Understanding Kale’s Heat Tolerance
Kale thrives in cool temperatures, typically between 45°F and 70°F (7°C and 21°C). However, some kale varieties are more heat-tolerant than others. When the temperature consistently climbs above 80°F (27°C), kale can bolt, meaning it will prematurely flower and become bitter.
Choosing the Right Kale Variety
The key to successful summer kale cultivation lies in choosing the right variety. Opt for heat-tolerant kale varieties that are bred to withstand warmer temperatures and have a longer harvest window. Popular choices include:
- Red Russian: This variety boasts deep red leaves and a slightly sweet flavor. It’s known for its resilience in warmer conditions.
- Nero di Toscana: This Italian heirloom variety features dark green, ruffled leaves with a peppery flavor. It’s a good choice for hotter climates.
- Lacinato Kale (Dinosaur Kale): Its crinkled leaves and earthy flavor make it a favorite. It tends to be more heat-tolerant than other varieties.
- Vates: This variety is known for its fast growth and resistance to bolting, making it ideal for summer growing.
Timing is Everything: Planting and Harvesting
- Early Planting: Aim to plant your kale seeds in the early spring or late summer/early fall when temperatures are cooler. This gives the plants a head start before the heat sets in.
- Afternoon Shade: Consider planting your kale in a location that receives some afternoon shade, especially in the hottest months. This will help protect the plants from the harsh midday sun.
- Harvest Strategies: Harvest kale regularly to encourage continuous growth. Pick the outer leaves, leaving the inner leaves to continue growing.
Watering Wisely: Keeping Kale Hydrated
Kale needs consistent moisture, especially during hot weather. Here’s how to keep your kale plants happy:
- Deep Watering: Water deeply and infrequently, allowing the soil to dry slightly between waterings. This encourages deep root growth.
- Mulching: Apply a layer of organic mulch, such as straw or shredded bark, around the base of your kale plants. This helps retain moisture and suppress weeds.
- Morning Watering: Water your kale in the morning, allowing the leaves to dry before nightfall. This minimizes the risk of fungal diseases.
Nutrients Matter: Feeding Your Kale
Kale is a heavy feeder, meaning it requires ample nutrients to thrive.
- Soil Preparation: Before planting, enrich your soil with compost or well-rotted manure. This provides essential nutrients and improves soil structure.
- Fertilizer Application: Feed your kale plants regularly with a balanced fertilizer, following the instructions on the package.
- Side Dressing: Apply a side dressing of compost or fertilizer around the base of your kale plants every few weeks to replenish nutrients.
Protecting Your Kale: Dealing with Pests and Diseases
- Pest Control: Keep an eye out for common kale pests like aphids, cabbage worms, and slugs. Use organic pest control methods like insecticidal soap or row covers to deter them.
- Disease Prevention: Good soil drainage and proper watering are essential for preventing fungal diseases.
Kale’s Summer Comeback: A Final Word
Growing kale in hot weather may seem like a challenge, but it’s definitely achievable. By choosing the right variety, providing adequate shade, watering wisely, and feeding your plants, you can enjoy fresh, delicious kale even during the summer months.
Popular Questions
1. Can I grow kale in containers in hot weather?
Yes, you can grow kale in containers, especially in hot climates. Choose pots that are at least 12 inches in diameter and ensure they have drainage holes. Use a well-draining potting mix and water regularly.
2. What are some signs of heat stress in kale?
Signs of heat stress in kale include wilting leaves, stunted growth, and bolting (premature flowering).
3. Can I grow kale from seed in hot weather?
It’s best to start kale seeds indoors in the early spring or late summer/early fall when temperatures are cooler. You can also try direct sowing in the cooler months, but it may be more challenging in hot weather.
4. How long does it take kale to mature?
Kale typically takes 60-75 days to mature from seed. However, heat-tolerant varieties may mature faster.
5. Can I eat kale leaves that have bolted?
While bolted kale leaves are edible, they can be bitter and tough. It’s best to harvest your kale before it bolts to enjoy the best flavor and texture.
