|Now that it's too late to apply a pre-emergent to the iris bed, what can I use to control these weeds and grasses that seem to come right back after digging them out? I know mulching will cause the iris to rot, so need some other suggestions.

|Ornamec is a very effective, selective grass killer that is safe to use around most shrubs, trees and ground covers. Check their extensive list on the label to be sure your desired plants are considered to be safe. Over The Top by Fertilome and Amaze by Green Light are similar products. Good luck with your weed eradication project.
