What is a recommended practice for ensuring the health of newly planted trees?

Choosing to water deeply and less frequently for newly planted trees is considered a best practice for promoting their health. This method encourages the development of a strong root system, as it encourages roots to grow deeper into the soil in search of moisture. When watering is done deeply, it allows the water to penetrate far into the ground, which helps to reach deeper roots and allows for better access to nutrients and water. This method also reduces the risk of waterlogging, which can occur with shallow, frequent watering.

Frequent pruning during the first year may actually stress the tree and potentially hinder its growth, as young trees need time to establish themselves before being pruned significantly. Using rocks for drainage can create pockets of dry soil that inhibit root development instead of helping drainage, as it can lead to uneven moisture levels. Applying constant fertilizer applications can lead to nutrient burn or imbalances in the soil, which may harm the tree rather than helping it thrive. Thus, the practice of deep and infrequent watering stands out as the most beneficial for newly planted trees.
