We've just got our first house and with it came a lot of new challenges in the shape of gardening.
One issue I have not managed to solve is weeds in our lawn.
I have been ripping these things out of the lawn a lot (see pic in post) but I feel like I can't win. There are big patches where you can hardly see the grass.
I know not everyone want the perfect grassy lawn, and I don't need perfection. But these things are growing and spreading at an alarming rate. I need to do something about them.
Where we are at now, I feel like we are past the point of ripping them up one by one. We need some wider, more effective solution.
What are these and how do I fight them in scale?
Extra pic:

Something is killing the grass in that picture. You need to figure out what it is. Common issues include fungal infections, insect damage or soil nutrient inbalance issues.
Dig around and see if you can figure out what is cause the grass to die. If it's an insect, identifying the insect can help you figure out how to control it. If it's a fungus, planting resistant species/varieties can eliminate the issue. For the soil nutrients sending a sample into a soil lab is relatively cheap and gives you an idea of what might be wrong.
The weed is buckhorn plantain. It's a perrenials that you have to remove the entirety of its roots (almost impossible). It's relatively easy to kill with a well timed application of 2-4D.

It does produce a massive amounts of seeds that can remain dormant for decades. So it will likely keep popping up for quite a few years.
