Agree. I once grew onions in bags...kinda by accident. I did nothing and they grew. That boosted my confidence. Radishes are pretty easy too. They both grew fast, with minimal care from me. Your location, your soil/climate etc also matters....its probs a good idea to look up what zone you are and pick the easiest growing thing. https://www.plantmaps.com/ if you dont know soil just grab a bag of cheap compost and a strong bag/recycled tub.

It does not have to be hard or a responsibility. Perfect is the enemy of the Good enough.
