Well, believe it or not, there is a product made that you can spray over the top of Iris and some other perennials that will kill the weeds and not the flower. It is called ‘Over-The-Top 2′. It is made by Fertilome, which is an independent dealer brand (meaning Lowe’s and Home Depot can’t sell it).

This product is wonderful for getting rid of Chickweed, Henbit (the purple flower), Dandelion, and many other broadleaf weeds. It literally can be sprayed directly over the plant, making sure to soak the weed leaves thoroughly so the chemical will get into the plant. This product is harmless to animals after it is dry. Of course, I would not let my dog eat the weed leaves after spraying, just to be safe.

If you cannot find this product where you live, email me at askthepigg@thepiggpin.com , and I will be glad to get you some in the mail ASAP.

Happy WeedKilling
