Question
Last year I started a flower and vegetable garden on my existing lawn.  I tilled the area very thoroughly but still fought the invasion of grass throughout the year.  Is there anything I can treat this area with that will kill the grass but not harm the vegetables or flowers?  I have tilled the area thoroughly in preparation for planting this weekend. Also if there is something I can use should I continue using after planting to control the spread of grass ?  Thanks

Dear Rick,
I realize this year it's a little late, but I do have a pretty good organic method for keeping weeds and grass to a minimum.  As for this year, and it will only work with bedding plants, rather than seeds, but I suggest you lay down a large piece of plastic, then tear or cut holes where you plant the bedding plants.  Another suggestion is wet newspaper around all the plants, then topsoil on top of the newspaper to keep it in place, but from what I hear that is really a lot of work and I prefer the plastic, which can be rolled up and tossed after the frost.  Now, for next fall, here's what I like to do.  I sow winter wheat after my fall tilling, just broadcast, and that stuff just seems to choke out everything.  Then in the spring, I just till it under.  It's very nutritious for the garden and it really does keep weeding to a minimum.
Hope this helps.  I'm on my first garden year at my new home, so I know what you mean about the grass and weed invasion.  I wasn't here in time to plant my wheat last fall.  I wish you well and I'm so glad to hear about your new gardening hobby.  
Kind Regards,
