Finally done done. Tile and the last wall boards went in a couple of weeks ago and its back up and running. Feels even better now that it's done!

Couple pics of the green roof. Doing great with intermittent watering and a little liquid fert once a month.

Help me! I have a kbg lawn. Half has been around for 4 years (sod) and half 2 years (sod). It was doing great, even earlier this year. Now I have what seems to be a clumping fescue moving in. It is everywhere.

For background, last fall I scalped, aerated, top dressed/leveled, and overseeded everything in a Twin Cites Seed kbg seed blend (not blaming them, love their stuff). Came in great before winter. My neighbor did the same minus scapling and overseeding. Same topdressing dirt. I do both lawns fertilizer and pre emergent. He has zero of this going on.

First, what do we think the grass is? Pics attached. Second, what is the fix? I have been pulling clumps out but there may be thousands. I will continue to do this for now. I am hoping this is some random annual, but I am likely to be disappointed. The only big difference between my neighbors yard and mine is I get significantly more deer traffic/poop.

Thanks in advance.

Finally got my green roof done. I didnt want to look at a black roof from my deck so I created a DIY living roof.

First off, yes, it was built from the beginning to hold the weight. I researched a ton before starting and ended up creating my own system out of easy to obtain materials (green roof products are expensive). It seems to be working so far with the inch of rain the other day.

The first layer is extra thick epdm which was adhered to the roof deck. I then added a thinner layer of epdm on top of that to protect the first layer. Next was a drainage mat which I made by drilling 1/4 inch holes (probably thousands) in a plastic dimpled foundation waterproofing membrane. The dimples end up holding a small amount of water. On top of the dimpled membrane, I placed a thick woven polyetheylene landscape/pond underlayment felt mat as a root barrier/dirt filter. Last was my custom lightweight dirt mix. I ended up doing 50% perlite (half course, half med) for drainage, 25% medium vermiculite for moisture/nutrient retention, and 25% compost for a little organic matter.

I planted sedum mats on top. They are doing great so far. In the pics a few spots look different because those mats were just laid out today as I ran out of sedums...

Pretty happy with is so far and adds some interest to my yard.
