What is a primary consideration when fertilizing newly planted trees and shrubs?

Timing of fertilization is crucial when caring for newly planted trees and shrubs because it significantly impacts their establishment and growth. Newly planted trees and shrubs are already under stress as they adapt to their new environment and develop roots. Fertilizing them too soon can stimulate excessive top growth at the expense of root development, which can ultimately harm the plant.

The ideal approach is to wait until the plants have had time to establish their roots, which generally takes several weeks to months. This allows the roots to grow and anchor the plant securely before the addition of fertilizer, which provides nutrients that can support their continued healthy growth. Proper timing ensures that the plants absorb these nutrients effectively, enhancing their survival and vigor.

While immediate fertilization, frequency of fertilization, and amount of water are important aspects of plant care, the timing of when to introduce nutrients is fundamental to promote healthy root establishment without causing additional stress to the newly planted specimens.
