Data Story

About Lawn Care in Kenedy County, Texas

Tough Conditions in Kenedy County

With a lawn difficulty score of 21.2, this county is much more challenging than the state average of 31.7. Maintaining a traditional green lawn here is roughly twice as hard as the national median.

Extreme Heat Dominates Climate

The county faces 155 days of heat above 90 degrees, pushing growing degree days to a staggering 8,379. While 29.2 inches of rain falls annually, it often evaporates quickly under the intense Texas sun.

Preparing Coastal Soils

Widespread Severe Drought

Drought is a severe reality here, with 93.1% of the county currently in a severe state. After 30 weeks of drought last year, water-wise landscaping is the most practical choice for homeowners.

Choosing Salt-Tolerant Varieties

Select salt-tolerant, heat-loving grasses like Seashore Paspalum or Bermuda. The growing season starts early, as the last spring frost typically passes by February 22.

  3. 3
    EstablishNov 11 – Dec 8

    Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.

Watering while it germinates

Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.

You’re in the transition zone — both cool- and warm-season grasses can work; the schedule above follows the species you selected.

Seasonal Lawn Care Checklist

Spring

  • Apply pre-emergent herbicide when soil reaches 55F
  • Begin mowing when grass reaches 3 inches
  • Start irrigation if rainfall is below 1 inch/week
  • Soil test every 2-3 years — adjust lime or sulfur as needed

Summer

  • Mow at recommended height weekly
  • Water deeply 1-2 times per week (1 inch total)
  • Avoid fertilizing cool-season grasses in peak heat
  • Scout for grubs and treat if >10 per sq ft

Fall

  • Overseed warm-season lawns if thinning
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering

Winter

  • Apply pre-emergent for winter weeds
  • Service mower and sharpen blades
  • Plan spring soil amendments based on fall test
  • Keep lawn clear of debris

Summers are warm (July averages 84.3°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 154.60000000000002 days above 90°F annually, warm-season grasses recover faster from summer stress than cool-season types. Aerate and overseed cool-season lawns by early fall, well before December 8; this is the best renovation window. Mild winters (January averages 57.0°F) allow year-round mowing for warm-season lawns and minimal dormancy.

Watering Guidance

Moderate rainfall (29.2 inches) means lawns benefit from weekly deep watering during summer stress. Currently, 100.0% of the county is in moderate drought according to the US Drought Monitor. Consider reducing irrigation frequency and allowing cool-season lawns to go semi-dormant during peak heat. Standard warm-season watering of 1 inch per week is usually adequate during summer. High heat accumulation means warm-season grasses use water aggressively — monitor soil moisture regularly.
