Eliminating Dallisgrass in San Diego Organically

San Diego homeowner suddenly overrun with Dallisgrass (not Dallas grass—Irving, TX has enough pollution). Wants removal without harming lawn.

Dallisgrass, Crabgrass, Johnsongrass: Unsprayable Weeds

No selective herbicide kills these without hurting desirable grass. Digging is the only chemical option.

Organic Program Makes Them Disappear

10 years organic = zero weeds. Microbes enrich soil continuously. Weeds can't thrive in rich soil. Sugar (4–5 lbs/1,000 sq ft), deep weekly watering, corn gluten, alfalfa meal, lava sand.

Year 1: 50% weeds → half in 2 weeks → gone by summer. Year 2: fewer. Year 3+: none.

Stop fighting weeds. Start feeding soil. Dallisgrass vanishes with the rest.
