I really, really, really, really hate nasty looking foliage and it's becoming a deal breaker for me. First, the cleanup in the spring when I see SEVS and EV's looking ratty. Then by August the backyard looks like a cornfield of brown foliage with a sea of brown scapes. If I had my way the foliage would be cut every week! So I'm taking advantage of this rain by ripping out cv's I don't want. With one hand I pulled out 4 this morning at 6:30 AM, and of course it's raining again. The ground is so soaked all you have to do is roll your eyes at them and they practically fall out on their own. I'm out of Sluggo and I emptied 24 cans of beer in 48 aluminum pie plates and this morning there are approx. 5 billion slugs in the pans. I hope they enjoyed their Pete's Wicked Ale.
What I would do is leave your plants as is and just close your eyes and count to 100 when you pass by them.
