Tyler Trimble has certainly earned the nickname of “Mr. Trees.”

As a third-generation farmer, a fruit tree specialist, and longtime nurseryman, he has personally planted over 10,000 fruit trees in Southern California soils over the past 20+ years.

Before launching his own business, Backyard Fruit San Diego, he was a manager at Walter Andersen Nursery in Point Loma for about ten years. He currently maintains a collection of exotic varieties and has created his own “food forest” orchard, with over 200 fruit trees.

Among his passions, he lists fruit tree health, orchard design, propagation, variety selection, soil science, permaculture, regenerative farming, and control techniques for insects, pests, and diseases.

And he’s an expert in the art of pruning fruit trees.
