You wouldn’t share the same drinking glass as your kids, but your plants don’t mind.
How many cups of half-drunk water find their way back to the kitchen sink in your house?
In our house, it’s plenty. And if you’re like most people, that water goes down the drain. But one day my parched plants visible from the kitchen sink window seemed to lean in my direction, and I had an idea. Now I keep the watering can right near the kitchen sink, and I pour the unused water from our drinking cups right in.
It makes the water supply a couple cups worth more full, and my plants are happy.
Don’t have plants to water? Consider using the water from your cups to wash the dishes, using the water from the tap only to rinse.
