Darwin’s wet season is imminent, bringing with it high humidity, monsoonal downpours, and powerful storms. Is your irrigation system ready to weather the deluge? We’ve put together an irrigation survival guide to help you through the wet season.
While it might seem counterintuitive to keep your irrigation system running during the wet season, relying solely on rainfall can be a risky strategy for your lawn. Rain can be inconsistent, and those who switch off their irrigation often neglect to turn it back on, resulting in a dry, patchy lawn come the dry season. Plus, the combination of heat and humidity creates ideal conditions for weeds and pests to flourish, so vigilance is key throughout the wet season to prevent an infestation later on.
The golden rule of irrigation during the wet season is simple: Switch it off when the rain falls! Keep a close watch on your yard and gardens, and only water if it shows signs of thirst. A smart irrigation controller can be a worthwhile investment, automatically adjusting your watering schedule based on the weather and your garden’s needs. Rainfall is the most significant factor influencing your irrigation needs. After substantial rainfall, adjusting your system is crucial to avoid overwatering, which not only wastes water but also increases the risk of root rot, fungal diseases, and other lawn problems.
To ensure your irrigation system not only survives the wet season but thrives into the dry months beyond, follow these essential survival guide steps:
Pre-Wet Season Checklist:
- Ease Up on Watering: As November ushers in the wet season, gradually decrease the frequency and duration of your irrigation. Monitor your soil’s moisture levels and only water when necessary. A smart irrigation controller can simplify this process, providing worry-free water management. Schedule watering for the cooler parts of the day – early morning or late evening – to minimise evaporation. Adding mulch around your plants helps retain soil moisture, further reducing the need for watering.
System Inspection:
- Leak Detection: Conduct a thorough inspection of your irrigation system, checking for leaks in pipes, hoses, and sprinkler heads. Promptly repair any leaks to prevent water loss and potential damage. Look out for split pipes, damaged hoses, and missing drippers. After storms, pay close attention to your system, as lightning strikes can damage underground wiring.
- Debris Removal & Continue Running The System: Clear gutters, drains, and sprinkler heads of leaves, branches, and any debris that could obstruct water flow and cause blockages during heavy rain. Running your system briefly each week can help prevent ants from blocking and damaging it.
Optimise and Adjust:
- Controller Settings: Adjust your irrigation controller’s settings to align with the reduced watering requirements of the wet season. Consider installing rainfall sensors to automate this process further.
Seek Expert Advice:
