Surprisingly, the mulch made it through the rain without any problems. Went ahead and ordered the edging so that I can get it down before I use up the remaining ton of mulch. There will be places needing fill after the edging goes in.
Went all out and spray painted the bottoms of the gutter drains that feed the water collection system. Original paint had worn off showing green 4 inch pipe. Mulch installation has gone well with the exception of my top heavy mulch transport cart wanting to turn over on my steep backyard.
