The answer to 'tree bare spots' is that there are several common causes, including disease, pests, soil issues, or lack of sunlight. Symptoms may include thinning leaves, discoloration, or patchy areas without foliage. Solutions can range from pruning, fertilizing, or treating for pests, to replanting the affected areas.
If the issue is minor, homeowners may be able to address it with DIY methods like aerating the soil, applying compost or mulch, or spot-treating for pests. However, for more serious problems like root disease or widespread damage, it's best to consult a professional arborist or landscaper who can properly diagnose and treat the issue.
