Tree service providers can address several common tree issues: powdery mildew caused by dry roots and poor air circulation, which affects oaks, maples and catalpas; drought stress from lack of deep watering in spring and fall; nutrient deficiencies from unsuitable soil that leaves trees deficient in iron, manganese or other nutrients; pest infestations from dead leaves/branches or malpruning that endanger property and spread disease; and soil pH instability or compaction from foot traffic or weather that damage roots. North Shore Tree Services is a company that can help with these issues.
