Storing Onions

I lifted my onions a couple of months ago, tied them in bunches of 10, then hung them in the greenhouse to dry off.

I now find 50% have gone rotten, is it the variety, or a bad year for onions?

    I think you should have dried them first then tied them Graham. If you tie them too early it retains the moisture around the neck of the bulb which leads to the rot. I dry mine for a few weeks before doing anything.

    Yes - they do need to be dried, preferably in the sun (ha ha).  We have a two-inch grid propped up over what is the cold frame in spring, and spread them in a single layer on that, if it's fine.  If not, they go on something similar in the greenhouse.

    I do like stringing them up though.

  • Thanks The bulbs and the roots were dry when I hung them up but the tops were still green, next time I will let the whole onion dry out before I hang them up.

    ...and brush off the soil as well, once it's dry.

  • Hi

    i keep an eye on my onions and if I see any showing sign of damage or starting I just chop them up and freeze raw in the freezer. Lift them out frozen and just add to soups and casaroles when needed easy

    happy gardening

    Yes - I did that this year too, for the ones that were damaged.  They need to be double wrapped, I discovered, otherwise the whole freezer smells of onions.image

  • Thanks all for the tips
