Grasses are a big problem for me also.  I use Ortho Grass-B-Gon (even though
I hate using chemicals) on Bermuda grass (worse than a pain in the bonky)
because I haven't found anything else that will keep me ahead of it.  If I
ever get it all out of my yard I will never have it again.

My second biggest pains are crabgrass and winter grass which is what I am
wondering about using the corn gluten on.  I usually have a lot of annuals
self sow so haven't tried it,  but this summer the crabgrass was so bad I
couldn't keep it out of the beds.  I can start the annuals in pots and then
set them out.  Do you have any idea how long the corn gluten is effective?
Since crabgrass keeps coming up all summer I will probably need to reapply
won't I?
