I mixed mine half moss and half compost and spread as mulch in herb bed. It does seem to mat pretty bad but does hold the water in and prevent weeds. I can post a picture if you want?

I would pay you for your extra bale? It makes the best potting mix I have ever used: 2 parts compost, 1 part SPM and 1 part perlite/vermiculite.

I'd love to see a pic.

One of the craziest things I've read about preventing crusting that I haven't tried yet is putting pebble sand on top.

I was going to use that to create some structure in the soil, but I didn't want it adding salt over time.

I've also tried compost on top, but it mats like you say.

Here ya go...

Just kidding. Thanks!
