What is good to kill grass-weeds in flower beds?

Bind weed and cooch grass is very hard to get rid of. You must dig it out making sure that you get the last inch, especially the roots. Do not put it into your compost heap as it survives. If there is a wide patch you can use Roundup or some other harsh systemic weed killer - however, the old down on your knees and start picking it out routine is the only answer...............

Reply:unless you want to kill your flowers,the only thing to do it moisten the soil and pull the weeds by hand.you moisten the soil so that you can pull root and all up so it wont come back!
Reply:PULL THEM UP THEN MULCH THE GROUND TO KEEP THEM AWAY FOR NOW. AFTER YOUR FLOWERS ARE GONE THIS FALL USE ROUND UP TO GET RID OF WHAT IS THERE. NEXT SPRING ROUND THEM UP AGAIN A COUPLE TIMES BEFORE PLANTING, YOU CAN GET MORE WEEDS THAT WAY BY LETTING NEW SEEDS SPROUT. BUT DO IT EARLY SO YOU WILL HAVE TIME FOR IT TO WORK. FOLLOW DIRECTIONS ON THE CONTAINER. YOU CAN PLANT ABOUT TWO WEEKS AFTER APPLICATION I BELIEVE. IT REALLY HELPS BUT THE MULCH WILL PREVENT WEEDS.
