Tree selection guidelines for California can be gathered at: http://selectree.calpoly.edu
Due to their flammability, certain tree species may pose a higher fire risk, especially when planted within 30-feet of a structure. Flammable trees may render your home indefensible during a wildfire. All other trees in this column should be planted and maintained at a minimum of 10 feet from the tree’s dripline to any combustible structure.
All trees should be chosen with on-going maintenance in mind, and planted or trimmed at least 10 to 30-feet from combustible construction, roofs, and wood siding. Trees should also be limbed-up to a minimum of six-feet above surrounding vegetation to prevent a ground fire from ‘laddering’ into tree canopies.
Specific water requirements can be obtained from local nurseries or from the Professional Tree Care Association
