We bought our house in Oct. of 2007 and had pines removed from the island in front a month later. We had these wonderful green plant leaves come up, but no flowers. This year, they came up as wonderful Iris. We want to have this area cleared out of the old Azalea bushes and spread the tightly net of Iris out in this area. Is it too early for me to pull them and have grading done, so that I can spreed them out? The house is over 30 years old, so I don't know how old the plants are, but they are very clumped together. I know I can break them apart, I just don't know when.
