As money is tight I have some white and red onion sets from last year in the bag left over. Some are a bit mushy, damp BUT they have perfectly healthy sprouting shoots about 3 inches high.

Can I still plant them for a crop this year ?

I'm suprised they have lasted this long. I assume you are referring to spring planted ones.

This will be their second year and will probably run straight to seed.

I wouldn't chance it. Get some new ones from Wilko - they're cheap and do well.
