So I took advantage of the nice weather and washed the mats right on the lawn while listening to "oldies" music on a Sunday. Lovely.
Having the basin and pails of water on the lawn meant I didn't just throw water down the drain but got to water the plants. It was so easy. Scoop water with the dipper and water the plants nearby and then tip the basin to water the lawn.
Nowadays it's been my practice to save and make full use of water. Even dishwashing water doesn't go to waste. It's earth-friendly and we benefit from the thriving lawn especially during the rainy days.
