Aah, gardening - my passion. When first diagnosed with Bronchiectasis, MAC and Pseudomonas, I was told never, no more by the doc. When I changed docs after a year and a half, both the new pulmonologist and I'D doc said gloves, N95 mask (with valve is ok) and change clothes and shower afterward. Also wet down potting soil before use and avoid peat mixes. And no chickens. Pretty sure the MAC came from the leavings of feral free range chickens in my Winter Texas yard, so I stay in while yardwork is being done out there, and only garden in pots.
