This one is actually up on a decomposing stump, where I had scattered some white millet. A step up is to put it on a porch railing, where it won't get so dirty. Better yet, put it under your eaves, where it won't get wet, either. Then we get into structures. Put the drum from a sawed-up tree on the ground.
Many birds like to eat a bit higher than ground level.
Sink a post into the ground and mount a platform at the top. Put a bit of molding around the edge to keep the seeds from rolling off. Let the molding leak at the corners so that the feeder doesn't fill up with water. Buy a hanging tube feeder with small holes for thistle or niger. Buy a hopper-type feeder that keeps the seed clean and dry and lets it out as needed.
