Abstract: An all purpose lawn and garden marker which is molded of a plastic material and therefore can be inexpensively manufactured. In addition, the marker is adapted to hold the required notice that a lawn has been chemically treated as well as other advertising material. The marker also functions as a water gauge so that the homeowner can determine the extent to which the lawn has been watered. Further still, the marker has a mowing height gauge to aid the homeowner in cutting the grass to the proper level. The homeowner can also utilize the marker in his garden to post a notice as to what is planted in the garden and to indicate the extent to which his garden has been watered.
