Back in the 80s at the school for the blind I grew up at plenty of people mowed. The pre prep would be key, walking the yard to remove branches or sticks, garden hoses, any other assorted junk. The actual mowing can work just like sweeping or mopping. Establish a pattern and zone it out. For example everything to the left of a tree first.

Or just hire it out, plenty of companies exist in most cities. Plenty of people do that regardless of vision.

We built a big patio, planted trees, a garden and non grass ground cover.

Weeding is quite a simple task because you can do it by touch. You need to be aware of the layout of your garden and garden beds, and know what is a weed to get rid of and a plant to keep. Because I'm relying on touch (even if I've arguably plenty of central vision left), I prefer not to use gardening gloves. Or I might have them on me, but only wear them when strictly needed.

My grandfather also uses poles (plastic stakes or metal poles, that way you don't risk splinters) and string lines along the garden beds at the unit he lives at to help guide him. In the garden at his family home though (he and grandma moved to their unit 9 years ago) I don't recall him using them. I suspect that was because he was very familiar with the layout and the garden beds had larger edging (rock lines and low rock walls) that he used for guideance. He always uses gardening gloves from memory.

As for mowing lawns, grandpa may have mowed the lawn occasionally, but he'd usually get my dad or one of my brother's to do it. If he did mow it on his own (which honestly wouldn't surprise me, we're quite the same in that we'll just go ahead and try doing something ourselves irrespective of the challenge due vision impairment in my case and total blindness in his) I suspect he'd use the rock lines a guide. So he'd get in line (using feet to feel the ground) and mow slowly till he hit the rock line, then turn and head back. In the spots where it would have been possible to cross onto a path, it'd be pretty obvious and the mower blades shouldn't strike the concrete or pavers, so you should be ok.

I'm only maintaining two garden beds and keep weeds out my paving (it really needs to be redone), and I'm often lazy about it. But grandpa was maintaining a full size garden - front and back lawns, five separate garden beds, greenhouse, a vegetable patch with four or five beds - on his own (bar the aforementioned help mowing the law) and he'd be out there most days. It was the best kept garden in the street as I recall, and he couldn't see a bit of it!

I actually just mowed my yard yesterday for the first time since my vision loss last year and I was (and still am) nervous. My father in law mowed for us last year, but he’s got other stuff going on. Not only was it hard driving the riding mower (we’ve got 1.5+ acres), I couldn’t hardly tell where I had mowed, so it was frustrating and difficult. Our front yard is fenced and only has a couple small trees so it’s not crowded, but I still managed to tap a tree with the side of the mower deck. By the time I finished, my nerves were shot.

I’m seriously considering hiring out the mowing, but a yard my size would probably be expensive. I’m a little more confident using the weed eater, but I’m not keen on mowing again. Keeping my equipment maintained (there’s no way I can read gauges, etc without magnification) will suck too. I’m looking forward to selling and moving to a new home with much less property to maintain.

I live in west Texas so I have limited grass. I do have a rather large vegetable garden. I grow it in lick tubs which are large containers used for cattle supplements. Having the garden in containers eliminates the need for weeding and simplifies things a lot. I have one tub for lettuce, one for spinach, three for tomatoes, etc.
