I ignored mine for over a decade and it quietly turned itself from grass into a naturally low-growing ground cover that looks like clover. It never needs watering and the only mowing needed is to chop down the stray weed here and there. It's quite nice.
Edit: I should add that the plant that took over is native to the area.
Hobbies take time and money, maintaining a house takes time and money. You never have enough time OR money. So you make the thing you have to do anyway your hobby.
