If it is not a lawn area, then cover it with a deep layer of shredded bark mulch.
If it is a lawn area, do not water more often than once a month in the cool season and once a week in the heat of summer. Weed seeds need continual moisture to sprout. If you allow the surface of the soil to dry out between watering, then you will not get weeds. Of course Mother Nature has her say in this too. The other thing you can do is to mow your lawn at the mower's highest setting. This works for most grasses except bermuda, centipede, and creeping bentgrass. Those should be mowed at the mower's lowest setting. Tall grass casts a deep shadow on the soil below. Any weed seeds that sprout need sunlight to take root, so any shade you can cast on those seedlings will help choke them out.
