Earlier this spring while out biking, I ran across an out-of-the-way creek back in the woods. Both sides of the creek bank were lined with thick, clean, emerald-green moss. A few days later, I harvested enough to plant around the foundation of my house. The moss is doing very well there, but it has since played host to a ton of different weeds. The moss at the creek may have had a few weeds growing up through it, but it was essentially a smooth carpet of moss. Is there any way to get rid of these weeds without hurting the moss? I really would like to capture that smooth, clean look that almost made me wreck my bike.
