Key Features of Leslie Roy Mesquite

Exceptional Structure: Grows with a rounded, even canopy that provides dense, filtered shade and minimal need for corrective pruning.

Fast-Growing Shade: Reaches maturity quickly, forming a wide, umbrella-like canopy ideal for patios, lawns, and streetscapes.

Watering Once Established:

• Summer: Deep water every 10–14 days; increase to every 7–10 days during excessive heat (over 105°F).
• Winter: Water every 4–6 weeks or as needed based on rainfall.

Drip Irrigation Setup:

• Placement of Emitters: Position 24 inches from trunk to encourage wide root spread.
• Flow Rate: 2–4 gallons per hour per emitter.
• Number of Emitters: 2–3 per young tree; add more as the canopy matures.
• Adjusting Frequency: Increase watering during extreme summer heat; decrease in cooler months.

General Watering Tips for Leslie Roy Mesquite

• Soil Check: Water when top 4–6 inches of soil are dry.
• Deep Soaking: Deep, infrequent watering promotes strong roots and structural stability.
• Mulch: Apply a thin layer of gravel or desert mulch around the base to retain moisture and prevent soil temperature fluctuations—keep mulch a few inches away from the trunk.
