If you mulch you are, yes. I don't think she ever used raised beds. She gathered moldy hay from neighboring farmers and spread it at least 8" deep on her garden. she never plowed, tilled, watered, or cultivated. The ground was moist, mellow, and soft - just like you want a garden to be. Being shaded from the sun, it didn't get overly hot either. Once a layer of mulch was on, the work level dropped a lot.
The soil just kept getting richer and richer. She'd pull back the hay to plant seeds or seedlings, and tuck it in as the plants grew up. If a stray weed did grow and poke its head through, it was easy to pull and just lay on top of the mulch as more mulch.
