Onions and Potatoes
After working so hard to grow your produce you would think
that it would be a great pleasure to sit down and prepare it for storage.
Unfortunately, I think this is my least favourite part of
the whole process, as it is rather time-consuming. However, it is very important
to review and sort your produce, or you could end up losing loads of it, which
would be a shame.
Onions
After lifting your onions they need to be dried out, either by leaving them on top of the soil at your plot, or by bringing them home to dry. Because I am a drive away from my allotment I tend to bring mine home in some very useful stackable plastic crates and then leave them out to dry, as a single layer, on a plastic sheet. If it rains then I can just nip outside and cover them, or pop them back into the crates.
Then comes the sorting. I tidy the onions up a bit so I can
check them over. They then go into the use first, use second or use last crate:
- Use first – any with bad bruising, or with thick green necks and stems – as these won’t keep.
- Use second – any with small holes or blemishes
- Use last – these should really be perfect as they need to store for the longest time.
If you put them all in together the damaged ones will rot
and make the good ones do the same.
I also pull out the small ones and put them aside to make
pickled onions.
How you store them depends on your own preference and
available time, but they keep best in low humidity with a temperature range of
2 – 4oC/ 36 – 39oF. This year I have decided to try
hanging them in labelled nets, suspended from hooks in the outdoor storage
area. I have also separated the red and white onions – this is just for ease of
use rather than having storage benefits!
If you have a bit more free time, or just prefer the effect,
then you can try making an onion rope. There are illustrated guides and videos
on the internet which will help you. Basically it involves a length of string
and threading the onions in, which certainly creates an attractive way of
storing onions.
Onions can also be stored on slatted shelves
Potatoes
As with onions, they need to be thoroughly dried before you
sort them. You should then brush off the soil, taking care not to damage the
skin.
Again I classify into use first, second and last. With
potatoes I check for bruising and holes. You also don’t want to be eating green
potatoes.
I store mine in Hessian sacks and these have worked very
well over the last few years. You can also use jute or double-thickness paper sacks;
but not plastic or polythene bags, as these make the potatoes sweat and rot.
The ideal temperature range for potatoes is 5 – 10oC/
39oF. If it drops below this in your storage area then it is a good
idea to cover the sacks with quilts/blankets or newspaper, as long exposure to
cold weather will cause them to develop an unpleasant sweetness.
I also check my sacks of potatoes on a monthly basis to pull
out any that have gone rotten to prevent them infecting the rest and to remove
any shoots.
Of course ideally – once I get my lovely B&B with
smallholding and a big farmhouse kitchen, the harvest sort can be done in
there, with some friends/family members to help and maybe a bottle or two of
homemade wine…
