Texas counties cannot zone or set a cosmetic lawn-height limit in unincorporated areas. Hidalgo County instead abates high weeds only as a public-health nuisance under Texas Health & Safety Code Chapter 343: weeds over 36 inches, or weeds within 300 feet of another residence, may be ordered cut.
Hidalgo County has no tree-trimming ordinance or permit for private property in unincorporated areas, because Texas counties lack general zoning authority. Property owners may prune their own trees freely; the county only addresses vegetation as a public-health nuisance or where it blocks a drainage easement or county road.
There is no Hidalgo County tree-removal permit or protected-tree ordinance in unincorporated areas, because Texas counties cannot zone private land. Owners may remove their own trees. The county's only vegetation authority is nuisance abatement under Texas Health & Safety Code Chapter 343 and protecting drainage easements and roads.
Hidalgo County's weed rule is nuisance abatement under Texas Health & Safety Code Chapter 343, not a mowing ordinance. Its Nuisance Abatement Program (adopted 2016) abates 'weedy lots' in unincorporated areas: weeds over 36 inches, or within 300 feet of another residence or business.
Hidalgo County does not set landscape-watering schedules; it has no such ordinance and no county water utility. Outdoor-watering limits come from each city, water supply corporation, and irrigation district, coordinated through regional drought planning and the TCEQ, since the county draws Rio Grande water via Falcon Reservoir.

Hidalgo County has no ordinance permitting or banning artificial turf; lacking zoning authority, it sets no synthetic-grass standard for private property. Texas law also blocks an HOA from banning water-conserving turf. City rules govern inside city limits.
