Poa Trivialis is difficult to control once established on a lawn. However, there are several management strategies that you can apply to prevent or reduce its spread.

The best way to control Poa trivialis is to prevent it from emerging during falls. Gardeners call this a pre-emergent strategy. Let’s discuss what this strategy covers. 

Pre-Emergent Method

To prevent both poa annua and poa trivialis from germinating and emerging from the ground, you must maintain a healthy and dense lawn. Here’s what you need to follow regularly. 

Keep Lawn Grass Long

You need to keep your lawn grasses at least three inches long. It will shade your lawn and resist the weed seed’s germination. 

That said, you should avoid mowing your grasses too short as it will make your lawn an ideal place for weed invasions. 

Avoid Regular Watering The Grass

You might have heard that gardeners need to water their plants regularly to maintain healthy growth. Indeed it’s true, but not here in case your lawn is vulnerable and more likely to grow poa trivialis. 

For such a lawn, you need to water the grass infrequently. Why? Because by doing this, you will make your lawn grass roots grow deep and healthy while searching for moisture. 

In contrast, if you water these grasses regularly, they won’t spend energy digging deeper for moisture. Consequently, they will be unhealthy and fail at fending off rough bluegrass.

Reseed Your Lawn

You should reseed your lawn with bunchgrasses during spring. The reason for reseeding bunchgrass is that these grasses won’t spread throughout your lawn and will dominate weeds. 

So, that’s all methods you can follow as pre-emergent steps to prevent poa trivialis germination. Now, let’s describe what you need to do if your lawn already has some rough bluegrasses. 

Post-Emergent Technique

If poa trivialis and poa annua are already present on your lawn, it can be a hassle for you to control or eliminate them. 

Still, you can prevent their growth and spread. Here are the essential steps you must take to prevent this detrimental rough bluegrass from spreading. 

Herbicide Treatment

Many gardeners apply herbicide in their gardens to kill weed seeds. But the problem with this treatment is that most herbicides like Genorate, tenacity, glyphosate, and velocity have been proven to fail at resisting poa Trivialis spread. 

Besides, some of these herbicides have been reported to kill other grass on gardeners’ lawns. However, among these herbicides, glyphosate has a reputation for killing all grasses that come in contact.

Hence, it might help you with weed prevention. But, you need to apply this herbicide cautiously, and after killing Poa Trivialis, you should follow the pre-emergent steps mentioned above. 

Perform Surgery

Performing surgery is the last step you should follow if all the other methods don’t give you promising results. 

You need to dig out that aggressive poa Trivialis from your ground to apply this technique. You can pull those rough bluegrasses out using your hands or a shovel.

After eliminating them, you should sod your lawn using one or more pallets of sod to cover damaged areas or any other bare spots. That’s it! That’s how you should perform surgery for weed removal.  

Hence, these are all the post-emergent techniques. We recommend following all of them and monitoring your lawn regularly to eliminate poa trivialis.
