Rock County does not ban native or naturalized landscaping, but the mandatory noxious-weed duty still applies. Near navigable water, native shoreland buffers are actively encouraged under NR 115. Any grass-height limits come from your municipality.
Rock County has no ordinance prohibiting native prairie or naturalized yards. Two rules still bind you. First, Wis. Stat. 66.0407 requires destroying designated noxious weeds (Canada thistle, leafy spurge, field bindweed and others) even inside a native planting. Second, if your land borders navigable water, the county's shoreland zoning under NR 115 favors keeping and restoring native vegetation in the 35-foot buffer, where clear-cutting is prohibited. Inside cities and villages, a municipal grass-height or weed ordinance may still apply to unmanaged turf, so residents converting a lawn to prairie should confirm local rules and keep noxious weeds out.
No county penalty targets native plantings; noxious-weed neglect is enforced under state law, and municipal weed/grass ordinances are enforced by the city or village.
