    Looking to slice overseed a lawn with known Necrotic Ring Spot issue. Want to introduce more fescues/per rye and improved KBG varieties. Do these choices sound appealing to you?

    1) 85% Creeping Red fescue, 15% KBG "Moonshine" mix from Reinders.

    2) 33% Creeping Red fescue, 33% Per Rye, 33% KBG "Shamrock" mix from JDL (park and rec mix)

    I know the critical constraint here is the KBG - I don't want to exacerbate the NRS problem by introducing weak cultivars of KBG.

    What do you think? If neither of these, ideas??

    I think I would lean on a local university that does turf grass and see what they think or a local extension agent that sees issues in the field everyday

    every area is so different I like to lean on local knowledge with seed varieties, you are smart to introduce new varieties some varieties from just 5 years ago have been surpassed with others

    I don't care for red fescue. Problem number two is that Kentucky bluegrass has a small seed and rather weak seedling--you may not get more than 10 percent "take" in an overseed situation. Ryegrass takes better, but it may not match your present grass. The only guaranteed method is to kill and strip sod--replace with top quality disease resistant sod. The chance of callbacks is greatly reduced.

    Or you can just replace the diseased spots with sod patch cut to match. Need sod lifter or sod cutting machine. Plus a big machette. Quick--easy.

    Sow what grows well and try to not let the NRS bother, in the future.

    I don't care for ryegrasses in general. Many of them "grow in clumps", and others get "rust". Regarding fine fescues (creeping, red, sheep, etc), some are okay, but many have issues during summer heat in sunny areas.

    Been seeing more & more lawns with "turf-type" tall fescue blended with KBG. I like it. My 2 cents worth

    For us here in Maine, the Per. Rye may only last 1 or two winters, so I treat that more as a quick cover. I have not seen a turf-type tall fescue blended with KBG, however, I am very curious about it. How well does it blend, and how does it look with a dark KBG like midnight? I am looking into creating my own blends, I have a local vendor that will blend what ever seed I want, and I have been trying to research the TTTF, of course most of the pictures that I can find aren't that great. FYI, most of my lawns are higher end with very picky clients so it will have to look good.

    For color and texture, I think your only option, is KBG. I personally, like the fine fescues, but the color is automatically lacking by comparison.

    OK - what KBG cultivars have good resistance to NRS then? The last thing I want to do is sow KBG seed that is vulnerable to a known fungal issue, exacerbating the problem...

    I haven't bothered doing that kind of research. We haven't had fungal problems and I either get the popular KBG or the mixture of the 3.
    I prefer the mixture and my 'high end clients" are cool with it. Research the midnight KBG and see how it stands up to NRS.
    What cultural practices promote/reduce NRS?
