HOA dead grass replacement

[Yuhei Kato]

Hello, I got a notice from my HOA that their is a area in the front lawn with dead grass and it needs to be replaced. I've had that property for 6 years now and that same spot has always had that issue. They've never seem to care until recently. I can patch it up but it's in a spot that doesn't get sun and the grass dies. I've never replaced grass but I have an idea on what to do I'm curious what other landlords do in this situation. Do you replace your self or pay someone to replace it? Any advice helps thank you.
