Q. Thick Grass in Lawn With Very Heavy, Thick White Root System

What is the grass called that is spreading all over the lawn and creeping into flower beds? It has wide blades and a very heavy, thick white root system that I can’t seem to get rid of. I’ve even applied Round-up, which slowed it down but didn’t get rid of it. I live in Iowa. It went into my creeping phlox, and I couldn’t keep it pulled out–eventually it took over. I want to kill it out so I can start over again.

You can try giving it a pruning. It is as simple as taking an inch or so off the top, just like a haircut.

I would also try treating it with a fungicide and make sure that it is getting enough water too. In many areas, it has been a hot, dry summer and it may just be going dormant due to this but it also may be a fungus attacking the plant.

Q. Why does grass keep growing in my creeping phlox?

Every year long blades of what looks like grass starts growing in my creeping phlox. I have to keep pulling it out by hand and some of it actually has roots.

The grass is just doing what grass does. You could of course try spraying an herbicide that kills only grass, as this article talks about: https://www.gardeningknowhow.com/plant-problems/weeds/using-herbicide-in-gardens.htm
However, my experience is that sometimes things don't work the way they're supposed to, and your phlox may end up getting damaged. Pulling is probably the best way to go, making sure you get as many roots as possible. You might try using an edging barrier to keep the roots out once you get them pulled up: https://www.gardeningknowhow.com/lawn-care/lgen/tips-for-choosing-lawn-edging.htm

Q. creeping phlox

Is creeping phlox available like SOD? My small lawn would look great in multi colors of phlox. Would broadcasting seeds be viable also? Mulch? Weeding?

Below is an article with tips on how to grow creeping phlox. Creeping phlox can be grown from seed or via nursery grown plants but it is much easier to do the latter. And, from what i understand, seeds may be difficult to find. To my knowledge it is not available in the form of sod.
