I am sure this has been discussed before but I am new to the iris world and still learning! What do you do to keep the weeds out of your iris beds. I have been hand pulling and its a lot of work. Last fall after weeding I put down preen. I started in late this season weeding the beds and its overwhelming. I know its not good to mulch around the iris. I mostly have TB's. Please share your experiences with me. Thank you.
