Yes, brown cedars can often recover with proper care. Adequate watering, pruning of dead or damaged branches, fertilization, and addressing any underlying issues like pests or diseases can contribute to the tree's recovery. However, the success of recovery depends on the extent of damage, the specific cause of browning, and how promptly and effectively corrective measures are applied. Consulting with a professional arborist for a thorough assessment can be beneficial in determining the best course of action for the specific situation.
