When we moved to this house 6 years ago, there were four big clumps of peach iris in front of the house. They came from the neighbor next door who planted them in her own gardens in the late 60's or early 70's.
At the time, I didn't know or care much about gardening....boy has that ever changed!
Here we are, April 2010. I pulled all the weeds and put down Amaze right after this pic was taken. The Amaze did an excellent job of keeping the weeds at bay for the remainder of the growing season. In my opinion, the Amaze works better than Preen!
