Summer Crisp Lettuce: A Heat-Tolerant Lettuce for Summer Gardens
Introduction
Summer Crisp lettuce is a heat-tolerant lettuce variety that is perfect for growing in warm summer months. Unlike most lettuce varieties that become bitter and tough in hot weather, Summer Crisp lettuce remains sweet and crisp, making it a favorite among gardeners.
Benefits of Growing Summer Crisp Lettuce
- Heat tolerance: Summer Crisp lettuce can withstand high temperatures, making it ideal for growing in hot summer climates.
- Sweet taste: Even in hot weather, Summer Crisp lettuce retains its sweet flavor without developing bitterness.
- Compact heads: Summer Crisp lettuce grows in loose heads that make it easy to harvest individual leaves for salads or let the entire head mature for a larger harvest.
- Slow to bolt: Summer Crisp lettuce is slow to bolt, which means it will produce leaves for a longer period of time before going to seed.
- Disease resistance: Summer Crisp lettuce is resistant to tipburn and rot, making it a low-maintenance crop.
Growing Summer Crisp Lettuce
Soil Preparation:
Before planting Summer Crisp lettuce, prepare the soil by adding organic compost to improve fertility. Lettuce prefers well-drained soil with a pH between 6.0 and 6.8.
Planting:
Sow Summer Crisp lettuce seeds directly in the garden in early spring or fall. Space the seeds 6-8 inches apart in rows that are 12-18 inches apart. Keep the soil moist, and thin the seedlings to the strongest plants once they emerge.
Watering:
Water Summer Crisp lettuce regularly, especially during hot weather. Aim to keep the soil evenly moist but avoid overwatering.
Fertilizing:
Fertilize Summer Crisp lettuce every 3-4 weeks with a balanced fertilizer. Avoid using too much nitrogen fertilizer, which can promote leaf growth at the expense of head formation.
Harvesting:
You can start harvesting Summer Crisp lettuce leaves as soon as they are large enough to eat. Harvest the outer leaves first, and the plant will continue to produce new leaves. Alternatively, you can let the heads fully mature for a larger harvest.
