Onion Tops Turning Yellow
After several years of having mixed results with onion sets, I decided to try plants this year. I think I followed the directions - 4" deep trench, 10-20-10 fertilizer in bottom, 2" of soil, then the plants. They did great for about 2 weeks. We've had a dry spell recently, so I've been watering them with a soaker hose about every other day. Now they are looking sick. The tops are turning yellow. Is this normal? Did I do something wrong? Can they still be saved? Any good advice would be appreciated.
