Solutions for Water Conservation in Irrigation
Mowing keeps your lawn neat and encourages thick growth, but timing and technique are essential.
- Maintain grass at 2–3 inches for optimal health, with frequent trimming during growth seasons.
- Scalping weakens the grass and makes it more prone to weeds.
Tips
- Keep mower blades sharp to avoid tearing the grass.
- Leave grass clippings on the lawn to provide natural nutrients.
Measure your current lawn height and adjust your mower settings accordingly.
Rainwater Harvesting Integration
Pairing irrigation systems with rainwater tanks ensures your garden relies less on mains water. This is not only eco-friendly but can also save money on water bills.
Smart Controllers
Smart irrigation controllers use weather data and soil moisture sensors to adjust watering schedules automatically. This prevents overwatering and ensures optimal hydration for your plants.
