Resumen

This text provides comprehensive guidelines for managing and aiding the recovery of citrus trees following exposure to freezing temperatures. It emphasizes the importance of tree dormancy in reducing susceptibility to cold damage, noting that evergreen citrus trees are less cold-tolerant than deciduous trees. The article outlines symptoms of cold damage, such as drooping leaves, bark splitting, and cold cankers, and describes the proper care needed for bearing groves, including adjusted fertilization, irrigation, and pruning practices.

Post-freeze care recommendations include a cautious approach to immediate interventions, reducing fertilizer based on the extent of tree damage, and prioritizing weed control and disease management. The article also covers the specific needs of young trees, suggesting removal of protective banks or wraps to prevent further damage and detailing how to reapply protection as needed. Overall, the article provides a detailed and flexible approach to help citrus growers minimize damage and promote recovery in the aftermath of a freeze. First published in June, 1992.
