I’ve been adding to mine for 30 years. The more real you want it. The more you will spend. The 2 things I’ve use a lot of for ground cover. Are free. Real dirt or soil from outside. Where there are an abundance of trees on the layout. During the fall gather up some leaves. Then grind them up in a blender. You seldom see nice manicured grass growing by the tracks or in the woods.
