A friend gave me a couple bricks of compressed coir mulch (the chunky kind). MegaMulch I think it’s called. With coir I always worry about salt content, but information is so vague on any particular brand.
If there is a salt issue, will a few rinses take care of it? Is there a quick way to test salinity of it?
Sounds like the brand sold at Costco? Should be washed, but don’t know what chunky grind might do. I had that brand in finer grind- never had an issue.
