Q.I Want To Plant Creeping Thyme Over A Large Area Which May Be An Acre. How Is This Accomplished.
I want to grow creeping thyme on a hill. The area is about one acre. The hill is in a mountainous area and once was heavily treed. The leaves were never raked, thereby allowing the leaves to become mulch. I cleared the area of all large branches and fallen trees. If standing trees were sick, dead, or too close to another tree(s), they were felled. This greatly cleared the area of thick tree growth. Generally, the area now has partial shade. A few areas get full sun. I am a fairly vibrant 76-year-old man. I do not wish to plant plugs. I would rather broadcast seeds. I would like to broadcast the seeds before a light showery day, a spring shower day. Also, as you call these plants “creeping,” does this mean they grow and become intrusive due to a lack of boundaries?

It is known as "creeping" for its spreading habit. It will not grow, vertically, but will creep, horizontally, along the ground. Here is an article that will help you to know what care that it requires, which is not much after seed broadcast:
