  3. 3.August: late-summer maintenance
  4. 4.October: light feed before overseeding or dormancy

Municipal watering restrictions vary by city — Phoenix, Tucson, and Las Vegas all have day-of-week limits. Deep, infrequent watering builds drought tolerance. Mow Bermuda short (1 to 1.5 inches) and watch for spring dead spot fungus.

Lawn Care Considerations in Castle Rock

Desert lawns face spring dead spot fungus in Bermuda after wet winters, plus rust fungus in overseeded perennial ryegrass. Phoenix, Tucson, Las Vegas, and most Southwest cities mandate watering restrictions by day-of-week, time-of-day, or volume budget. Bermuda is the only viable warm-season grass — drought-tolerant and heat-loving. Many homeowners are converting to xeriscape or artificial turf due to water cost; check city rebate programs.

Mow frequency
Bermuda: weekly during active April through October growth. Overseeded perennial rye (winter lawn): every 7-10 days November through May.
Mow height
Bermuda: 1 to 1.5 inches. Overseeded rye: 2 to 3 inches.
Water needs
Bermuda needs approximately 1 inch per week from rainfall plus irrigation. Overseeded rye needs more (around 1.5 inches) in cooler months. Most cities mandate watering restrictions by day-of-week or volume.
Irrigation
Required. No lawn survives the arid Southwest without irrigation. Many cities offer rebates for water-efficient irrigation upgrades.
