To cut costs (while still getting season-long crabgrass, etc control with just one treatment), several competitors here wait until their second application (late spring) before applying their pre-emergent. This seems to always work here in the upper Midwest. This means applying a fairly heavy rate of balanced fert in early spring, then in late spring........ applying the fert + pre in late April -- mid June so it lasts. Also, land-grant universities recommend heavy fert in late fall, with the next heaviest rate of fert in early spring. So, to me this makes sense. This is a program change from the normal of year's past, but to me it makes sense. rscvp, thanks-------especially with the costs going up.
