The answer to 'shrub bare spots' is that there are several common causes, including poor soil conditions, disease, pests, or too much shade or sun exposure. Symptoms may include thinning foliage, wilting, or dead patches in the shrub. Solutions can include improving soil quality, pruning, pest control, or moving the shrub to a more suitable location.
If the bare spots are limited, homeowners may be able to address the issue with DIY methods like applying mulch, aerating the soil, or transplanting new shrubs. However, for more severe or recurring problems, it's best to consult a professional landscaper who can properly diagnose the issue and recommend the most effective treatment.
