I planted some red onions (bulbs) in garden early Apr. I dug in compost before and topped them w/ a bit of manure once they were 8" or so. They were doing great til 2 wks ago (end of Jun.) when they started flopping over! I know they're nowhere near ready-they're still small. There's about a doz. of them that seem to be fine and growing upright. We've had some really cool weather up til now. Does anyone know what happened and do you think I should mulch them now that the hot weather's here? This is the first year I've grown onions so I don't know! I really appreciate your advice. Cheers!
