This aluminum soaker attachment is great for watering individual plants. Watering individual plants can reduce weed growth between plants, and it can save water, too. This attachment is better than just running the hose at the base of the plant because the water comes out more gently and mulch and soil don’t get washed away, which can happen with a hose, even when the water is turned on low. Sometimes this is called a bubbler or an aluminum diffuser flood nozzle.
