We're into the careful water-management time of year; to keep the garden alive I must water periodically, but I supplement watering by taking gray water from the kitchen out to pour systematically around the garden on different plants and zones. The number of times one turns on the faucet to wash hands, rinse a cup, let it run till hot, etc. runs water down the drain but I keep a bucket for that. A bunch of trips out during the day keeps the garden in operation when the heat would otherwise crisp it up or I'd break that bank watering with a sprinkler.
