HARVESTING ONIONS GROWN IN RAISED BEDS
Article by David Marks.
Harvesting onions grown in raised beds is exactly the same as if they were grown in the open ground. If you harvest onions at the correct time and the correct manner they will store for the longest period possible.
We also give some useful hints and tips on how to store onions in the winter months for the longest possible storage time.
WHEN TO HARVEST ONIONS
Onions should be harvested a week or two after the top foliage falls over. You need to wait a week after the foliage dies to let it shrivel up and effectively seal off the top of the onion.
Keep an eye on the weather though and factor that into the time of harvest. Onions should be harvested on a warm sunny day, the warmth in itself will help shrivel up any green foliage.
We wait until about three quarters of our onion crop has had its foliage fallen over for a few days and harvest on the next sunny day. Onions will always mature at different times so this is not an exact science although mid August to early September is the normal harvest time.
HOW TO HARVEST ONIONS
Because the soil in a raised bed is far more crumbly than
open ground, harvesting onions from raised beds is easy.
Simply grip the top foliage with one hand, the top of the
onion with the other and gently twist the onion in the
ground from side to side until the roots break from the
Remove the onion and gently brush off any excess soil with your hands. Don't clean them, just remove excess soil, there shouldn't be much, if any, of it. Lay the onions on a dry surface, a patch of dry grass is fine and leave them in the sun for a day or so. At this stage, if rain threatens remove them to a dry, airy place and lay them out.
There are specific conditions which will affect the storage
of onions when they have been harvested.
Keep your stored onions cool but well out of frost.
Dry conditions are best for storing onions, damp conditions will cause them to rot.
Let air circulate around your onions, this will stop rot and help keep them dry.
We tie a piece of sting across our garage at the far end and hang the onions of it by their necks. This works well although any method which keeps to the above rules will ensure the onions store well.
