yeah, quackgrass, witchgrass, it has a lot of names. Only thing it's good for as far as I'm concerned is the roots are a good medicinal for UTI.
Only way to fully control it that I know of is to continually get rid of the aerial parts as soon as they crop up, so the roots eventually starve and die. That can take at least 3 years, and it will take constant vigilance after that to keep it from creeping in again. It also spreads from seeds as well.
Dang girl - you are making progress! That's fantastic. A garden is a lot more fun when it's not a constant battle...I have some volunteer clover that I never weed out. It's slowly spreading. The heat will get it in a couple more weeks, but it'll come back when the weather is more favorable for it.
I can't imagine! Please tell me more.
