My ID doc told me 6 years ago that it was not necessary to stop gardening - just be smarter.
Here are the adjustments I made -
Gloves while gardening, thrown in the laundry frequently with my garden clothes. Garden clothes, gloves and shoes stay in the garage until laundered so I don't bring anything into the house.
No more peat moss, anywhere in my gardens or pots.
No more playing in dry soil - always wet it before working.
No more dumping dry soil, compost or mulch - I pay a helper to do it if my husband cannot, and stay away until it has been watered down.
No using the mower, leaf blower, or rake and staying away while it is in use. If I must do it, wear a KN-95 mask (the one where when you breathe out, a one-way valve opens to expel the moisture - much more comfortable than the N-95.)

With these precautions I have stayed NTM free in spite of hundreds of hours in the garden and working with plants.

I have MAI and am not a gardener so I don’t know how any doctor can say such a thing. Not that I don’t think we need to be careful outside under the circumstances, as usual Sue gives great tips for gardening, but it’s very hard to say how any one of us got infected. We can’t even say how long we’ve been infected. We guess, we theorize, but we don’t know.
