Here we go....
There are many grades and types of 'weed block'. Commercial grades take decades to break down a little bit.
Most of your weeds are not growing "up through" but DOWN through from seeds on top.
Different types of stone keep weeds at bay better than others. Deeper stone is BAD, and increases the ability of the weeds to grow.
No plants in the bed give weeds more light and water to grow. Good landscape design and practices trumps the wreck n ball /throw in whatever you think looks good , method.
I HATE chemicals...but...PREEN PREEN PREEN! Use more, use more often... it works.
NO WEED KILLER EXISTS that will work better than PULLING weeds on a REGULAR BASIS. Dead weeds are dropping seeds, and are just as ugly as live weeds.
You can get bad infestations under control in about a month pulling once a week and applying preen after each removal session. Then good luck finding a maintenance company that will actually pull weeds, seems they are just as lazy as we are, and prefer to believe there is a magic spray somewhere that will work better.
Weekly round up and regular Preen applications do work, but most do not know how to use Round Up without major overspray damage to your shrubs and lawn.
MOST IMPORTANT... anyone pulling weeds without a 'dibbler' or some tool to work the roots out...are wasting their time.
Good luck !
