Hello Gardeners, I'm Amanda McNulty with Clemson Extension. I have at times used a small plastic child's pool as a place for birds and insects to get water in my back yard vegetable and cut flower garden. It is not elegant but the dog didn't like it and I wanted to find a purpose for it. I added a large dead branch extending over the side as a bird perch and ladder for bees if they fell in the water. The nice thing was that when I went out of town for a couple of days, it held enough water to last until we returned. The downside was when I saw mosquito larvae, wiggle tails, dancing about. But that wonderful organic naturally occurring compound BT is formulated in donut shaped dunks that last all summer in a small pool and are completely safe for beneficial insects and other wildlife. You can find BT mosquito dunks in most garden centers.
