No, I’ve done this myself a zillion times. And if you look at my link or do a web search you’ll see all sources say this same thing. If you tried it before and didn’t have the same results then that’s atypical. Maybe something was wrong with the scallions you used, or some other problem
Could depend on what’s in the local tap water (mineral content as well as pH), in addition to lighting as weeeeum mentioned. I have some scallions on my planted aquarium (no fish, but I lightly fertilize for the plants) with a grow light, and I can harvest one of the four plants once a week. So even with active grow light and fertilizer, the once a month per plant statement seems right. Also note I started with seven plants, all from the same store-bought bunch, but three of them died over the first couple of months.
Other than that they were in a cup at the kitchen window
Definitely not enough sun. They really want cooler temps but 6-7 hours of full sun per day. Windows are terrible for plants because the sun, annoyingly, moves.

I don’t think they get enough sun. Other than that they were in a cup at the kitchen window, with the water replaced every couple days.
