The most likely areas in which weeds may become a problem, is that where the lawn is sparse and poorly managed. Remove occasional weeds by hand, ensuring that all the roots are removed.

This should be done promptly before the weeds seed themselves. Regular mowing is the best way to control broad-leafed weeds. Every time you mow you favor the grass and hamper the growth of the weeds, which are not adapted to withstand regular mowing.
