Kale is believed to have originated in the Eastern Mediterranean and Asia Minor, where it has been cultivated for over 2,000 years.
Harvest kale by picking the outer, larger leaves first, leaving the central growing point intact. Regularly prune any yellowing or damaged leaves to encourage healthy growth and prevent disease.
Harvest kale when the leaves are young and tender for a milder flavor. The best time to harvest is in the morning after the dew has dried. For the sweetest taste, wait until after the first frost, as cooler temperatures enhance the flavor.
General Prevention: To prevent pest problems, practice crop rotation, ensure adequate spacing between plants for good air circulation, and water at the base to avoid wetting the leaves. Mulching can help retain moisture and reduce weed growth, which can compete with kale for nutrients.
