I'm very much a newbie to plants in general however since learning about regrowing certain vegetables I had to give it a try. So I've had spring onions (or scallions) for about 6 weeks now. They were store bought and after consumption the roots were put in water. Then about 3 weeks in, I put them in potting soil instead. They're still doing good, apart from some yellowing dry tips? I've read this is normal but this is spreading quite far down some of the onions now. Are these ones gradually dieing?
I can't find any specific information on raising these in soil, and how often to water, how much sunlight etc. Could anyone share their experience on this? Are the dry ends happening from too much sunlight, too little watering, or something else?
Here is an image of the onions currently, if it helps. Thank you!
