Many people are coming in with questions about fertilizing trees and shrubs right now. Many shrubs are just starting to show signs of leaves or even flowers if you have forsythia or magnolias in your landscape. Most plants have a big growth spurt in early spring and continue to grow more slowly during the summer months. You want to have the fertilizer in the ground so that the plants can make use of it when that growth spurt happens. Now that the ground is workable and leaves are just starting to pop you can apply your fertilizer.
Tree and shrub fertilizer comes in several forms – granular, spikes and water soluble. Spikes and granular fertilizers are usually only applied once or twice a season while water soluble fertilizers will need to be applied more often. Use what works best for you and be sure to follow the instructions on the package for best results. Over fertilizing can stress plants and make them more susceptible to disease and other damage.
