@kayskid - I have an issue with masks while doing hard work too, but I make an exception when handling the potting soil. What I do though, is dump it in a large plastic tub, wet it down thoroughly and walk away to let any dust settle, then use it to fill my pots and baskets. Also, wood mulch can be a source of MAC, so I hire someone to spread it for me. Then, before I work the soil in an area that has the mulch, I wet down the mulch, rake it out of the way, do my planting or digging, then put it back. Just trying to be as safe as I can while getting the job done!
