Excessive rainfall can lead to soil erosion, root damage, and waterlogging, which may harm plants and trees. Saturated soil reduces oxygen availability to roots, potentially causing stress or disease. Young trees are particularly vulnerable to wind and water damage due to their underdeveloped root systems. Overflowing storm drains and improper water flow can also result in localized flooding, threatening both gardens and nearby properties. Without proper preparation, these risks can lead to long-term damage to landscapes and soil health.
