What initial care is essential for newly planted trees and shrubs?

Watering immediately after planting is crucial for the establishment and health of newly planted trees and shrubs. When a tree or shrub is planted, its roots are often disturbed or damaged; thus, it is essential to provide adequate moisture to help the plant recover and establish itself in the new environment. This immediate watering helps to settle the soil around the roots, reduces air pockets, and ensures that the roots can absorb necessary moisture.

Proper watering during the critical initial period after planting promotes root growth, encourages the plant to establish itself securely, and aids in the absorption of essential nutrients from the soil. Without sufficient water, the plant may experience transplant shock, leading to stunted growth or even death.

Other options, such as applying pesticide or adding decorative stones, do not provide the immediate benefits that watering does. Similarly, pruning back branches is generally unnecessary and can be detrimental right after planting, as the plant needs all of its photosynthetic capacity to support recovery and growth.
