Improper tree planting techniques can lead to stunted growth, root girdling, and even tree death. For example, planting trees too deeply or using gravel for drainage can harm root systems. Additionally, over-mulching or watering too frequently can damage the tree's bark and roots. Fall planting, when done correctly, minimizes these risks and provides trees with optimal conditions for root development. Homeowners and gardeners in northern regions should aim to plant by early October, while those in southern areas have a longer window extending into December. Following research-backed practices can significantly improve the survival rate and health of newly planted trees.
