Very old and immobile people garden and do it successfully. You make it sound like this is a difficult task. It is not. I assure you.
I do not live in any state.
You can make excuses as to why you do or don’t do things but to claim gardening one’s yard is difficult is laughable.
If you’re spending hours a day weeding your yard, perhaps whatever turbo fertilizer you’re using should not be used.
All of what you said is true, but the time required and difficulty of said task is insignificant.
If your ailment is just laziness then perhaps leaving the house just isn’t for you.
