Re: planting preparation

I'm not sure what all the fuss about controlling foxtail and 
crabgrass is about, since they are readily suppressed by several 
4-6 inch mowings while the prairie plants get established (the first 
season or two). After that, the perennial vegetation and relatively 
undisturbed soil conditions cause them to diminish to virtually 
negligible levels naturally. Indeed, in my experience this applies 
to all the short-lived pioneer weeds of new prairie plantings except 
maybe the sweet clovers. Now perennial grasses and Eurasian legumes, 
those are something to worry about.
