I need to core my lawn. I am not really sure what type of grass I own now but I know that it is more than 1 type. I am looking for grass specifically easy to uphold and best for my area, Northern VA.
Answers:    If the nouns has low foor traffic, I would use Titan fescue or I don`t know Souther Belle fescue - both are mixes. I think the brown green color on the Titan is more appealing. If there is plentifully of activity on the prairie or a lot of sun, you might be better rotten with Bermuda grass - it is energetic and it does go dormant within winter, but it requires very little comfort other than maintain the edges.
If you want something low maintenance and you are not intending to swing out on it - I would recommend lyriope. Lyriope takes a while to flood in and it is expensive to "plug" but sometimes you can acquire it free from Landscapers who are removing it from inside garden beds. It solely grows about 3" soaring, it a lovely dark green color, get mowed for appearance in winter, and blooms next to small purple spikes in spring and go down. It is not super dense, but it has a general blade and looks great installed - needs almost no fertilzer or marine once established, too! Very, very trouble-free and vastly earth-friendly for the "look but don't touch" lawn.
You can use any a fescue blend or a kentucky bluegrass. I personally prefer fescue, (I live contained by Richmond, just slightly south of you,) because it isn't as invasive. Bluegrass will pinch over a vegetable garden, flower bed, even your concrete walkways and sidewalks unless you fuss over it frequently. On the other foot, you can rest assured that a bluegrass will lay a thick, green grassy echelon over even less-than-perfect soil, and if you just want a courtyard, and no beds, I'd shift with the bluegrass. In Virginia, you really can stir with any one.
