Love your Iris.
The tomatos are very interesting to me. My daddy grew his the last years of his life by simply laying a 2 cf bag of Miracle Grow on the ground. He punched a few holes in the back side before laying it down to allow for drainage. Then he cut a split in the center of the bag. Planted the tomato in the split. Watered it in and that was it. He kept it watered, but it took very little water. He had many many tomatos this way. He did stake them, if I remember.
