Verified Growing Facts

Leafy greens such as lettuce, spinach, kale, endive, escarole, mustard, and arugula generally prefer cool growing conditions. Many leafy-green seeds germinate well in cool soil, while soil temperatures above about 80°F can inhibit germination for some crops. Once established, excessive heat can encourage bolting. Extension guidance commonly recommends close spacing while maintaining enough air movement to reduce disease pressure.
