Weed/Ground Cover

This Ground Cover/weed is taking over my yard.

What is it?

How can I kill it/remove it without destroying my grass?

The picture is kind of fuzzy but that looks like a lot of "Ground Ivy", "Creeping Charlie", " Glechoma hederacea".
This "weed" grows best in certain soil conditions that are not good turf grass conditions so the first step in control is a good, reliable soil test. Contact your counties office of the Ohio State University USDA Cooperative Extension Service about having a good, reliable soil test done (and I know some of these do not do the test themselves but they know who will).
Then dig in with these simple soil tests to see what soil you currently have,

  1. Structure. From that soil sample put enough of the rest to make a 4 inch level in a clear 1 quart jar, with a tight fitting lid. Fill that jar with water and replace the lid, tightly. Shake the jar vigorously and then let it stand for 24 hours. Your soil will settle out according to soil particle size and weight. A good loam will have about 1-3/4 inch (about 45%) of sand on the bottom. about 1 inch (about 25%) of silt next, about 1 inch (25%) of clay above that, and about 1/4 inch (about 5%) of organic matter on the top.

2) Drainage. Dig a hole 1 foot square and 1 foot deep and fill that with water. After that water drains away refill the hole with more water and time how long it takes that to drain away. Anything less than 2 hours and your soil drains too quickly and needs more organic matter to slow that drainage down. Anything over 6 hours and the soil drains too slowly and needs lots of organic matter to speed it up.

3) Tilth. Take a handful of your slightly damp soil and squeeze it tightly. When the pressure is released the soil should hold together in that clump, but when poked with a finger that clump should fall apart.

4) Smell. What does your soil smell like? A pleasant, rich earthy odor? Putrid, offensive, repugnant odor? The more organic matter in your soil the more active the soil bacteria will be and the nicer you soil will smell.

5) Life. How many earthworms per shovel full were there? 5 or more indicates a pretty healthy soil. Fewer than 5, according to the Natural Resources Conservation Service, indicates a soil that is not healthy.
and see what you should do to fix that soil.
There will be some that will tell you they have really good and healthy soil and they still have "Creeping Charlie" and yes you can have that. but in a good, healthy soil any you do get will be easier to remove.

This ground cover has small red berries that don't show in the picture.

I'll look into a soil test.
