How to Space Your Trees and Shrubs

February Fire-Smart Tips from the UC Marin Master Gardeners

Spacing of Trees and Shrubs for Fire Safety:
● Consider creating separation by increasing the spacing between tree canopies while considering flat vs sloped terrain.
● Maintain vertical clearance of at least 3X the shrub’s height between the tops of shrubs and the bottom of the tree canopy. This can be done by pruning the shrub down, or pruning smaller, easily ignitable tree branches up, or both.
● Remove dead trees.
● Plant spacing, size control, and maintenance are more important than the type of plant.
