Zone 0 landscaping: what stays, what goes, and what about the trees

The ember-resistant zone rewrites the first 5 feet of your yard. It does not require scorched-earth landscaping, and in a county that runs from pine forest to desert, the honest version has range.

Quick answer: Zone Zero requires noncombustible ground cover in the 0 to 5 foot ember-resistant zone: no bark mulch, no woody shrubs against the wall. The April 2026 draft scaled back blanket vegetation rules amid concern over mature trees and shade, and local authorities may allow well-maintained trees. Your Riverside County fire authority sets the specifics.

The redesign

The five-foot ring, replanted

Out: bark and wood-chip mulch, juniper and other resinous shrubs, climbing vegetation on walls, and plantings under eaves and vents.

In: gravel and decomposed granite (already the native language of Coachella Valley yards), pavers and stone, low succulents in noncombustible beds where your authority allows plantings, and clean hardscape paths that double as access.

On trees, honestly: homeowners across California pushed back on early drafts precisely because mature trees provide needed shade, and the state responded. The current draft is more permissive than the headlines suggested, and local rules may allow well-maintained trees near the home. In Idyllwild and the high country, where homes sit under mature pines by design, this distinction is the whole conversation: do not preemptively remove a healthy tree; verify with the Riverside County Fire Department or your city's department first.

Beyond five feet

Where landscaping meets wildland

In the San Jacinto communities and on Temecula's vineyard-country hillsides, Zone 0 is only the innermost ring: Zones 1 and 2 (5 to 30 and 30 to 100 feet) still govern the broader property. The free assessment covers all three zones, so wildland-edge homeowners see the full picture, not just the first five feet.

Questions

Quick answers

Do I have to remove my trees?

In most cases, no. The April 2026 draft scaled back blanket vegetation restrictions after widespread public concern about mature trees and shade, and local rules may allow well-maintained trees. This matters doubly in the pine-forested San Jacinto communities. What Zone 0 clearly targets is combustible ground cover and shrubs in the first 5 feet. Verify specifics with your own fire authority before removing anything.

What replaces bark mulch in Zone 0?

Noncombustible ground cover: gravel, decomposed granite, pavers, stone, and concrete. Desert-adapted and valley yards alike can swap the 5-foot ring to hardscape without losing the planting design further out.

Does drought-tolerant automatically mean fire-safe?

No. Some drought-tolerant plants are resinous and burn readily. In the ember-resistant zone the standard is noncombustible, not just low-water.
