Arizona Landscaping; It’s Time to Fertilize Citrus Trees

Temperatures are finally warming up and Spring is right around the corner! With this change in seasons comes changes in the landscape of your HOA community or commercial property and it is important to properly prepare the plant and tree materials for the upcoming warmer weather.

January/February marks the kickoff to Spring here in Arizona and is the perfect time to begin fertilizing Citrus Trees in your landscape. Citrus Trees, like many fruit bearing tree species, are heavy feeders so it is important to their health and fruit bloom that they receive the proper fertilization and water prior to their full bloom. Amount of fertilizer recommended to use varies depending on size and age of the tree. When buying your fertilzier it is a good idea to refer to the back of the package to find proper amounts to use for your tree. We have also included a chart that details recommended amount by the University of Arizona Cooperative Extension which you can access here.

When it comes to applying the fertilizer to Citrus Trees, you can do it one of two ways. One way to go about this process is to purchase a spray fertilizer which you would spray directly on the leaves of the tree. The other option is to spread fertilizer on the ground near the tree. When applying fertilizer via the ground it is important to spread the fertilzier from the tree to the length of the canopy, avoiding placing fertilizer directly on or near the trunk of the tree.

Finally, due to the dry climate that we have here in the desert southwest it is crucial to the health of the trees to water them thoroughly following the application of fertilizer. This ensures that they get the water they need to utilize the fertilizer in a way that will promote bloom and growth.
