Ft Ross lawn care, month by month
California sits in the turf transition zone, so the calendar depends on which grass family you have — they run on opposite schedules. Cool-season lawns (tall fescue, bluegrass) peak in spring and fall; warm-season lawns (Bermuda, Zoysia) do everything in the warm half. Not sure which you have? Start with the grass identification guides.

Reading the Ft Ross lawn year
Transition-zone timing cuts both ways in Ft Ross: cool-season lawns get their big renovation in early fall (overseed Oct 28 – Nov 12), while warm-season lawns establish in late spring (Mar 12 – Mar 26) and want their last feeding by Nov 1 – Nov 15. The one shared date is the pre-emergent window in spring — both families need crabgrass stopped before soil crosses 55°F.

Frequently asked questions
When should I overseed my lawn in Ft Ross?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Ft Ross that means roughly Oct 28 – Nov 12, timed 45–60 days before the average first fall frost (Dec 27) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When should I plant warm-season grass in Ft Ross?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 12 – Mar 26 in Ft Ross, once soil has warmed well past the last frost. That gives new grass a full growing season to mature before its first winter dormancy.
When do I put down crabgrass preventer in Ft Ross?
Aim for Feb 5 – Feb 26 — the estimated stretch when Ft Ross soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 26). It's an estimate: a soil thermometer reading 50–55°F at 2″ depth for several days is the precise trigger, and pre-emergent must go down before crabgrass sprouts, not after.
When should I stop mowing in Ft Ross?
Keep mowing as long as the grass grows — in Ft Ross that's typically until Dec 20 – Jan 10, around the average first fall frost (Dec 27). Take the final cut slightly shorter to discourage snow mold.
What grass grows best in Ft Ross?
California is in the turf transition zone, so both families are common: Tall fescue and Kentucky bluegrass alongside Bermuda and Zoysia. Tall fescue is the usual cool-season pick and Bermuda or Zoysia the warm-season ones — they run on opposite calendars, so identify what you have first. See the grass guides linked below for identification and care.
