Sprinklers
System
Sprinklers throw water over a wide area and can quickly cover a lawn or large bed. They are convenient, but usually the least water-efficient option because wind and warm sunshine increase evaporation, while wet leaves can encourage disease. Use them thoughtfully and only where broad, even coverage is genuinely needed.
How it works
A sprinkler connects to a hosepipe and sprays water in a fixed, oscillating or rotating pattern. Position it to cover soil and plants without soaking paths, walls or neighbouring gardens. Run it in the early morning or evening, when less water is lost to heat and wind. Check how deeply the soil has been wetted rather than judging by a damp surface. Avoid frequent light watering, which encourages shallow roots, and switch it off after useful rainfall.
Best for
Sprinklers are most suitable for establishing a newly seeded lawn, watering a large lawn during prolonged dryness, or moistening broad areas of young plants where hand watering would take too long. They are not ideal for greenhouse crops, containers, tomatoes or plants prone to foliar disease, because their leaves are wetted unnecessarily.
Tips
Choose calm conditions and adjust the spray so water stays within your garden. Water thoroughly but less often, allowing moisture to reach roots. During a hosepipe ban or temporary use ban, sprinklers are commonly restricted, so check your water company's rules. Do not use a sprinkler simply to keep an established lawn green.
