Open soil not only helps, but is key in my opinion, for successful frost seeding. (That whole seed to soil contact thing actually is important..).

I would burn it if possible. If not possible, yes I would till in the thatch. Soil to seed contact critical.Quick question. I am converting some of my lawn to switch and I have sprayed 3 times in the last two months. Am I going to need to do anything else? Till, rough up the soil?

I hear ya bud...I still feel like switch is actually a mythological creature...i have maybe seen 3 switch plants...my plan is to smoke all the cool season stuff come october/november....spread more switch feb/march....kill all the spring stuff and see what happens then....my fear is in my area it got very dry early on and anything that may have germinated might have died, or its hiding in plain sight, so either way my plans will hopefully get me headed on the right path next yearDisappointed ! What I thought was great switch grass turns out was Foxtail. (First year ever trying to plant it) I frost seeded it, used pre herbicide kept mowed.
Sure looked like switch. Is it worth seeing what happens next year? Or start over.
Skip, Should I do that in mine? I frost seeded, simazine/gly and mowed 4 times. I just mowed it again this weekend. Should I nuke it and turn the ground over? Any help would be great. Here is a pic.That’s frustrating!!!
go in and frost seed it this year. Eliminate the possibility of it being drilled too deep. That is a pretty common one. Frost seed a nice thick amount of seed…. Do 2 varieties (kanlow & CIR for example).
Other possibilities on why things fail beyond planting too deep…
1) seed that was not stored right at some point in process from harvest to seeding.
2) got wet enough to germinate & then it dried out from lack of rain. We did experience this in iowa in June this year.
3) with germinating & drying out…. Soil types impact this. Extremely good soils can tolerate this better. Mediocre soils don’t have tolerance for the dry conditions.
This year- if seed did germinate at that wet point in June & it did dry out- likely lost some or all of what germinated. I know I lost some seed this year to that big dry spell.
4) seed not stratified…. Need freeze/thaw cycle many times over. Some switch has thick hard seed coat that will not germinate without it. Lot of variables on why this is & when seed is or isn’t like that.
bottom line: probably one of above or possibly something else going on. Let’s get it frost seeded with 2 varieties in February next year. Do not give up.
