Waterwise has calculated that using water in our gardens and outside accounts for over 50% of peak demand for water in summer. Many parts of the UK have had hosepipe bans in recent years, and with more of us moving to metered water, it makes sense to think about water efficiency outside.
Washing bikes and cars
Use a bucket and sponge rather than a hosepipe. The Energy Saving trust have calculated that this uses about 90% less water.If you do use a hosepipe, fit a trigger nozzle so that you only use water when required.
An established lawn should not be watered. If patches go brown in a dry spell, they will soon green up when the rain returns. Set your mower blade higher so that grass is not cut too short. Longer grass helps to shade the soil beneath, reducing the water lost to evaporation.
Only water plants when they show signs of needing a drink or if they are newly planted. Watering early morning or preferably late evening minimises the water lost to evaporation and prevents scorching.
Target watering at the plants' roots and ensure that you drench the soil there thoroughly. It is easier to target watering if you use a watering can.
How to Reduce Watering
Mulching beds will seal in moisture, preventing evaporation. Apply a deep layer of chipped bark or other mulch to moist soil. Choose plants that are more resistant to drought. Many herbs originate from the Mediterranean and are able to survive dry periods. Perennials and shrubs should not need much watering once established.
