The answer to 'fence dead trees' is that there can be several common causes, including disease, pests, drought, or other environmental stressors. Symptoms may include discolored, wilting, or falling leaves, peeling bark, and a lack of new growth. Solutions can vary, but often involve removing the dead tree, treating any underlying issues, and replanting with a more suitable species.
In many cases, homeowners can handle basic tree maintenance and removal themselves, but it's important to be cautious with larger or damaged trees that could pose a safety risk. For complex issues or large trees, it's best to call in a professional arborist or landscaping service to properly assess the situation and recommend the safest and most effective course of action.
