Data Story
About Lawn Care in Allen Parish, Louisiana
Taming One of Louisiana's Toughest Lawns
With a difficulty score of 19.1, Allen Parish is one of the most challenging places in the nation to maintain a lawn. This score is nearly 15 points below the Louisiana state average, requiring extra dedication from local gardeners in hardiness zone 9a.
High Humidity and Long Growing Seasons
Allen Parish experiences 84 extreme heat days annually, matching the state average for high-temperature stress. The 60.7 inches of annual precipitation provides plenty of moisture, but the 6,459 growing degree days mean you will be mowing frequently through the long southern summer.
Addressing Very Acidic Soil Conditions
The local soil pH is 4.98, which is critically low compared to the ideal 6.0-7.0 range. While the sand content is a healthy 36.6%, the extreme acidity means heavy soil amendments are likely necessary to prevent nutrient deficiencies in your grass.
Navigating Severe Drought Conditions
Allen Parish has endured 24 weeks of drought in the last year, and currently, nearly 25% of the parish is in severe drought. To conserve water, prioritize irrigating in the early morning to minimize evaporation and help the turf withstand the 100% abnormally dry conditions currently present.
When to Plant in Allen Parish
Bermuda or Zoysia grass perform well in this climate if planted after the last frost on March 3. Be sure to establish your lawn early in the season to prepare for the first fall frost, typically arriving around November 25.
