I bought a new watering nozzle in Walmart's auto center. I like to rinse down my back patio with lemon scented soap and water ( its' supposed to keep insects away). This nozzle has a container to put soap in. You can turn the dial to water only and then increase the amount of soap. It has 7 different sprays. I also used it with water soluble fertilizer. I really like it because it's not too heavy. All of the nozzles I have had for adding fertilizer end up leaking really badly. You can also unscrew the soap container while the water is on and put more soap/fertilizer in it.
