Welcome applevalle,
There are lots of folks here who are physically challenged and manage to keep their gardens going. Thankfully most people concentrate on what they do in the garden each day and not dwell on the negative stuff. (We do have a Grumpy Thread for when people feel like letting off steam.) I had to re-learn gardening about 10 years ago when I became disabled. Thought about not having a garden and nope, that was not gonna work for me. Even just a few pots or raised beds will keep you in the game. Just do what you can each day and no matter how independent you are, please ask for help when you need it.
All of the above are good answers. You could contact the local Boy Scout group to see if anyone is working on an Eagle Scout project. One surprising way I received help was from the missionaries from the Mormon church. They come around with a plan to talk about religion but I told them I had too much work to do and, sorry, had no time to chat. Their eyes lit up as they asked what they could do to help me. They returned the next day (without the white shirts and neck ties) and were happy to get good and dirty. Here is the mess that my garden was in before the young men helped:
After the two men and I worked all day the garden looked a lot better. All I had to do was add plants and water.
The young men even managed to move my 10 foot long table (a gift from Home Depot when they renovated their garden center). The table is a good height so I can sit and plant seeds or re-pot plants.
The landscape fabric was covered with bark chips as it is easier for me to walk on. All the plants are in raised beds and large plastic tubs that I get from local landscapers (free) when they plant trees in the area. Since the soil never needs to be tilled all I need is a hand trowel to do my planting. When I am too week to lift heavy bags of soil/mulch/manure I holler for help, even if I have to pay someone. Some of my neighbors work for money; some work for lemonade or a beer.
If I need to sit I use a shower chair to sit on while I am working in the yard. I had tried sitting on plastic milk crates but...well, my butt was too heavy.
I was thinking of taking my old commode chair and adding wheels to use it as a gardening chair...with storage under the seat!!
My old body has good days and bad days. While resting in the house on the bad days I like to plan for the good days. Here is a super tall raised bed that I built (over several weeks) to keep out the rabbits. You can believe I had some help to fill it with planting medium.
