Gosh, thanks for sharing. I came up with an idea for planting water-loving plants like wild water iris and elephant leaf plants. Florida, planting soil is sand as well, and water drains away too fast. So I bought little plastic swimming pools, poked a few holes in the bottom, dig a hole and set it in the ground, then added gravel or stones in the bottom and topped with soil. I then planted the wild water iris bulbs and they bloomed beautiful early this Spring and then in Summer too. The flower is a very pretty blue. I used the same idea for the elephant leaf plants and they are growing well inspite of our drier than normal weather. By setting them down in the ground the roots or bulbs stay cooler, thus can survive longer than if planted in a pot or just in the ground. I also don't overwater my plants, that way they can handle hot weather and lack of rain better than a plant that is watered every day.
