I built this pondless waterfall last year. Wanted to get your thoughts on how best to winterize it. There are many factors to be considered. We get leaves in the fall, snow and freezing temperatures. In addition there are plants in the center as well as on the side plus some landscape lighting... Last winter I just drained the water out and pulled the pump. Had alot of nasty leaves to deal with in Spring + a couple minor leaks around the top. I thought of covering the entire thing but am worried about the plants and lighting. Also don't like the appearance of the tarp. Thoughts?? What do you guys do?? Thanks!!
