Can I mulch the iris tubers?

You can mulch the iris tubers as long as you do not cover the actual tubers. However, the clover is not coming up through the tubers so you should be able to mulch around them. If you cannot, it is time for you to divide your iris tubers and replant them. I suggest that this be done in the Fall, though.
