I purchased three magnolia trees about a year ago and I a would like to know if I need to use fertilizer. On the label that came with the trees says that needs monthly fertilization. The trees looks great.
In order to know what nutrients your soil is lacking if indeed it is, you will need to have a soil sample done. Soil samples will tell you exactly what your soil needs in order for your plants, trees and lawn to thrive. Contact your local cooperative extension office to arrange a soil sample testing.
