How to Control Wire Grass in Your Lawn
By: Julie Day
Our farm in North Carolina is infested with wire grass – and I do mean, infested! It’s growing in the fields; it’s growing in the paths; it’s tangling in the grapevines; it’s everywhere! Next to the poison ivy, it’s probably the single most insidious weed we’ve got here.
Sometime back, I gave a cursory mention of wire grass in my article on How to Control Bermuda Grass, because, yes – botanically speaking – wire grass is an uncultivated form of Bermuda grass. But as someone who’s dealt with it in numerous yards in my life, I’m here to tell you that – metaphorically speaking – this stuff is the devil!
It grows right under garden edging. It grows right over landscape paper, mulch, gravel, sidewalks, and forgotten rakes. It even twines up into shrubs, where it reaches out to wave and laugh at you as you walk by. The roots are so deep that when you try to pull it, they break. And just when you think you’ve got wire grass under control, it releases seeds that fly into all the areas you just weeded. Remember my Weed-Proof Vegetable Garden? Well, it was – except for the wire grass.
How to Deal With Wire Grass
Back in the heyday of tobacco farming around here, farmers didn’t mess around with wire grass – they would patrol their hundred-acre fields and hand dig every tiny sprout. They wouldn’t dare allow even one patch to take hold.
It’s one of those weeds that doesn’t respond very well to “cultural practices,” meaning that if you want to be rid of it, you’re going to need an approach just one step shy of nuclear annihilation. Wire grass has to be tracked down and either completely killed or completely removed, and that’s likely to need doing more than once.
Like other forms of Bermuda grass, wire grass turns brown during the winter, so you can easily spot the telltale patches in a fescue or bluegrass lawn. If you’re planning to dig wire grass up, it’s best to do it while it’s brown and dormant. If you’re going to spray wire grass, take note of the patches in your lawn, then wait until it’s green and growing.
Here are some tips on controlling wire grass in your yard:
- Grass Clippings: Don’t mulch wire grass clippings – you don’t want to spread the seeds around.
Once upon a time, I made peace with wire grass. At that time, I had a large fenced in backyard with four dogs running around in it, and the wire grass was the only thing that stood up to their energetic paws. As they trampled the regular lawn grass, the wire grass crept out into its place, so I fed it, watered it, mowed it, and everybody was happy. It’s not a bad looking grass if you can keep it out of your flower beds.
And I must confess that I didn’t pull it out of my vegetable garden this year. With the garden completely surrounded by wire grass, it seemed like a losing battle. And for all my preaching, I’m really not much of a weeder either. The veggie plants did just fine, though by summer’s end the garden was a bit of a tangle!
Wire grass is one of those plants that you can either live with or fight with. But if you’re willing to take an aggressive approach and stick with it, it’s possible to keep wire grass at bay.
