I often have trouble with onion seedlings. They shrivel up and die a week or two after sprouting. The ones in the tray (the photo on the left) started dying a couple weeks ago. I don’t know what I’m doing wrong.
Fortunately, I also did some winter sowing and seeded onions outside in plastic bottles (photo on the right). These are doing much better. They look good to me. They are growing very slowly, but surely.
Last night I picked up my new book, The Gardener’s Bible (my bedtime reading), and read about onions. “To grow good onions, give them what they need and then don’t bother them. Come harvest time, you’ll have a crop that will bring tears to your eyes” says the author, Edward C. Smith. I think this is the problem. The onions don’t seem to like all the attention of my seed trays under the bright lights and warm room temp.
What is it about onions? Are they shy? My other seedlings are doing well.
