When should you harvest kale?

Kale can be harvested when the leaves are young and tender, typically around 55 to 75 days after planting, depending on the variety. You can start picking the outer leaves once the plant has reached a height of about 10 to 12 inches. For the best flavor and texture, it's ideal to harvest in the cooler months, as the leaves can become tougher and more bitter in hot weather. Regularly harvesting encourages new growth, allowing for a continuous supply throughout the growing season.
