For me, from my research just keep your grass short which makes it harder on the quackgrass as it needs energy from sun to grow fast thus why it's always taller, keep cutting forces it to burn up its' energy store allowing regular grass to take over - I seem to have some success. It's a dilemma though since people say keep grass longer to conserve water.... sigh... the joys of wanting a nice green lawn...
