PG&E Offers Resources for California Arbor Week

March 8, 2022
To kick off the weeklong event, it is reminding customers and their loved ones of all ages to mind what’s overhead and underground when adding new trees or shrubs to an area.

Planting the right tree in the right location helps promote fire safety, natural gas safety, reduces power outages and ensures beauty for years to come. That’s why each year, Pacific Gas and Electric Company (PG&E) likes to recognize and honor trees during California Arbor Week. To kick off the weeklong event, it is reminding customers and their loved ones of all ages to mind what’s overhead and underground when adding new trees or shrubs to an area. This will lower the risk of wildfires or damage to powerlines and gas lines, making hometowns safer.

PG&E has many online materials, including free downloadable guides, with easy tips, charts and photos that help explain how, what, and where to plant the safest trees for each area, found here.

It’s never too early to learn about trees and powerline safety, so PG&E also has fun and educational games, puzzles, and checklists just for kids at Each activity is grade and age appropriate.

“California Arbor Week reminds us that trees provide many health and environmental benefits to our hometowns but there are hazards to avoid above and below the ground. Trees that are small when planted may grow to heights that can reach overhead powerlines or create root systems that interfere with gas lines. We want your trees to be healthy and safe for our communities to enjoy for a long time,” said Peter Kenny, Senior Vice President, PG&E Vegetation Management & System Inspections.

Here are some main safety reminders when it comes to planting a tree, but more robust information can be found in PG&E’s free downloadable planting guides, which includes characteristics of recommended trees, how to care for a tree, and much more.


  • Call 8-1-1 at least two days before planting trees or landscaping to have underground powerlines and other utilities marked. You can also do this by visiting Professional locators will arrive at the digging site to mark the approximate locations of underground utilities with flags, spray paint or both.
  • Visit for planting guidelines specific to your region and specific to whether you live in a High Fire-Threat District (HFTD), as outlined by the California Public Utilities Commission.


  • When planting a new tree near powerlines outside of a HFTD, leave space for it to remain at least 10 feet clear of all powerlines throughout its lifespan, including crown expansion and ensure it is no taller than 25 feet at maturity.
  • Within a HFTD, plant only low-growing, fire-resistant shrubs near powerlines. This can extend the defensible space around your property. For more information regarding defensible space visit


  • Never attempt to retrieve any type of balloon, kite, drone, or toy that becomes caught in a tree that is near a powerline. Trying to retrieve it yourself is extremely dangerous. Leave it alone, and immediately call PG&E at 1-800-743-5000 to report the problem.
  • Always look up before pruning a tree. Only experts certified to conduct tree work near powerlines are qualified to prune trees in these locations.

In 2011, the California Legislature designated the week of March 7 to March 14 of each year as California Arbor Week, and to urge California residents to observe the week with appropriate tree planting activities and programs. March 7 is the birthday of famed horticulturist Luther Burbank.
