**No—don’t rely solely on moisture from the ground.** It may eventually harden some of the mix, but you can’t count on enough water reaching all of it evenly, leaving weak or powdery areas.

The “dry” method is often misunderstood: **Quikrete Fast-Setting Concrete can be poured dry into the hole, but you then add water.** That is the manufacturer’s recommended method; “no mixing” does not mean “no water.” Follow the water quantity and placement instructions on your particular bag.

Also check which product you have. Quikrete is a brand with several mixes; ordinary concrete mix should be mixed with water before placement unless its instructions specifically allow otherwise.

For wood posts, use lumber rated for ground contact and shape any exposed concrete to shed water away from the post.
