I have used Roundup as an herbicide for years. Just don't use it from January until after the bloom season is over.

I use Treflan as a preemergent. I till it in when I am making a new bed. If the bed is established, I top dress with it in the fall and in the early spring. Most weeds are taken care of except for morning glory and a few others.

The few weed seeds that sprout are hoed or hand pulled.

Using the above make for a clean garden and save time and energy. WalMart has Roundup and garden centers or co-ops have Treflan. It is generally cheaper at co-ops. I know of a ten dollar difference at one garden center. This is on the twelve pound bag, I believe.
