I planted some onion sets in late March but it seems all the rain we've been having may have caused root rot and they're dying. I pulled one up and one of the sides looked mushy so I'm assuming there's no recovery from that. They looked so healthy and then started turning yellow and drying up one leaf at a time. I think I'm down to the last 2 leaves on each and even those have yellow tips so I'm not expecting too much from them.

What I'm wondering, is it too late to replant from sets? I know onions like some cool weather so, should I just wait until end of summer and replant for a fall harvest?

Thanks for the info!
