Tom Karwin, on gardening | Falling Leaves – Santa Cruz Sentinel
Take care of your garden
Earlier this month, as the leaves began their seasonal behavior, Governor Gavin Newsom signed legislation banning “exhaust fumes and evaporative emissions from new small off-road engines” produced in 2024 or later. This applies to gasoline leaf blowers, lawn mowers, edgers, edgers, chainsaws and other garden equipment. These small all-terrain engines (SORE) are well documented as sources of ozone polluting the air, particles hazardous to health and noise destructive to peace.
This California action to protect our environment is the first of its kind in the United States and is a general shift from fossil fuels to green energy. However, this only applies to SORE produced in 2024 or later. All existing gas-powered devices continue to be in use and could likely be functional for several years beyond 2024.
Several environmental groups supported this bill. While many would also have applauded a phase-out of existing SOREs, the state’s long-term approach is responding to complaints from groups like the California Landscape Contractors Association and the National Association of Landscape Professionals. In fairmess, some landscapers have switched to electrical or manual equipment (including leaf rakes), and none have reported financial constraints related to the local ban on leaf blowers. Some green landscapers have probably attracted new clients.
At least 100 US cities (including Monterey) have already restricted the use of gasoline leaf blowers, which are major polluters and possibly the most annoying SOREs.
The Santa Cruz Safe and Healthy Environment Coalition has advocated for a local ban on gasoline leaf blowers for years and has even raised money to ease the transition to battery-powered blowers.
Here are the steps that individual gardeners could take towards a green gardening environment:
Buy only electric or manual gardening equipment and replace any gasoline-powered appliances you already own with electric ones. (Battery life has improved.)
Only hire landscapers who only use electric or manual gardening equipment. If you have electrical equipment, ask them to only use your equipment in your garden.
Contact elected officials in your local government to ask them to restrict or ban SORE outright. There are several model prescriptions that could be adapted locally.

Here are some resources on SORE:
Visit the California Legislative Information website (leginfo.legislature.ca.gov/) and search for AB 1346, the new California law.
Visit the California Air Resources Board website (ww2.arb.ca.gov/) and search for SORE. This site contains a lot of information on the impacts of these devices.
Visit the website of the Santa Cruz Coalition for a Safe and Healthy Environment (chasesantacruz.org) and browse their in-depth and thoughtful information on this topic. And support their work!
Here are the upcoming webinars on gardening topics.
