Yes, we have Grandma Day once or twice a week when school is out, so Mom can get a few things done. Yesterday he was short on sleep from our family "last day of school" party that kept him up way past bedtime.
Early in my MAC journey, my ID doc told me to live my life "cautiously but without fear" and we talked particularly about gardens and swimming in pools.
In my gardens, I have mainly perennials, which are easier to care for, with a few annuals thrown in for fun. I garden on "blocks" - so if I am going to work in the morning, I shower afterward. Afternoon or evening, shower when I go back into the house (which may be after supper on the patio). If I am just going out for a few minutes... Oh, well - I figure any exposure is minimal.
For routine weed-pulling, watering, etc I do not wear a mask. For raking, blowing, trimming, digging or mulching I mask. Better yet, for the heavy stuff, I hire a grand-nephew.
When planting pots, I mask up, mix my soil in a big tub & wet it down. When planting beds, I wet them down first. Then I feel comfortable planting without a mask.
My garden clothes go down the chute when I take them off, as much due to pollen as any concerns about germs. So I have several sets, but that suits me.

I have been off meds for over 3 years with no reoccurrence, so I guess it works for me. Each person needs to find their own comfort zone.
