Tips from the pro
What is meant by injecting fertilizer into trees and shrubs?
Trees also require nutrients in order to grow properly. Sometimes the soil alone can’t provide sufficient nutrients for trees. Besides that, trees are continuously competing with the other plants around them for available nutrients.
That is why fertilizer injections directly to the tree roots are recommended at least once a year (spring or fall). The fertilizer is in a liquid form and is specially formulated to promote optimum growth.
