I am from SW Missouri. Have family in the Mount Vernon, Sarcoxie, and Springfield area. Yellow is just about my favorite color for flowers of all sorts.
So what’s the details on the soil mix you put together?
That’s why people in Missouri are always talking about the weather — and don’t forget: If you don’t like the weather right now, just stick around - it will change.LOL
Here’s one mix:

There’s lots of info on the net for different mixes. I went lighter by a little on the perlite than this called for. Then I damped it with some Miracle Gro plant food.
Oh yeah, I also mixed in some course builders type sand as suggested in many mixes.
