Is a seed pre-emergent indicated for an iris bed? I keep weeding out the iris bed, but inevitably seeds of weeds end up in the ground, and weeds grow all over again. I was thinking of putting some kind of seed pre-emergent like Preen on the ground in between the irises ... Any advise or experience? Thank you.
