How to Pickle Onions

Filed under: root veg — Tags: onion, pickle, recipe, shallot — TopVeg @ 1:37 pm

The main thing you need to pickle onions is plenty of time, otherwise it is quite straightforward!

pickled-onions-pink

most people use shallots for pickled onions
make a brine solution by dissolving 8oz of salt in 4 pints of water
skin the onions – using a stainless steel or silver knife – as they will discolour
cover the onions in a cold brine solution for at least 24 hours. Place a dish over the top of the onions to make sure they are covered with brine. The brine draws the water out of the onions & makes them crispy.
drain the onions from the brine
fill a clean, sterilised jar with onions & cover with spiced pickling vinegar

pickled-onion-jars

The spiced pickling vinegar can be of any flavour & it is worth trying a few different ones.

It is possible to buy spiced pickling vinegar, or you can make your own using a different vinegar (cider, wine, raspberry vinegar etc) & add your own combination of spices. Pre-mixed pickling spices can be found in supermarkets, or you can add your own combination of chillies, ginger, pepper, mustard seeds etc..

It is very easy to pickle onions, just time consuming! But a jar of home-made pickled onions is a treat – or an excellent gift or Christmas present.

Harvesting Red Onions

Filed under: root veg — Tags: harvest, onion, red onion — TopVeg @ 8:02 am

The red onions have been harvested because the leaves were flopping over and the soil was very wet.

The onions have been spread out in an open slatted box and left to dry in a very airy place. More information on harvesting onions and when to harvest onions can be found by clicking the link

Gornalwwfc was watching a TopVeg video on YouTube & asked this question about
onion fly:

    does anyone have any ideas or ways of dealing with *onion fly* my
    allotment plot (near Dudley)is rife with it the onions leeks and
    even garlic plants are all affected and none of the shops I’ve been
    to sell any kind of spray

This is the reply from TopVeg:

Hi Gornalwwfc
Bad luck – onion fly is a real problem.

Once you see the damage, the flies have laid the eggs, & the maggots have hatched out & are doing the damage.

* Lift and destroy plants effected – making sure there are no maggots left on the soil.

* Onion flies are attracted by the smell of fresh manure, so don’t plant your onions, leeks and garlic on freshly manured soil.

* Some garden centres sell chemicals to treat the soil where onion fly maggots are a problem.

Onion Fly (Latin name -Delia antiqua) is a serious pest of onions, leeks and garlic.

Botrytis Neck Rot in Onions.

Filed under: pests&diseases — Tags: disease, onion, onions, store — TopVeg @ 1:48 pm

Onions must be checked for Neck Rot (latin name – Botrytis allii, B. squamosa and B. cinerea) once they have been lifted, because it destroys onion bulbs in storage.

onion-neck-rot

White onion varieties are more susceptible to onion neck rot, but red and yellow varieties
may suffer. Garlic, shallots, chives, and leeks are also affected by neck rot.

Plant Onion Sets

Filed under: root veg — Tags: onion, plant, sets — TopVeg @ 10:44 pm

Onion sets are immature onion bulbs specially grown for planting.

check-onion-sets

Gardeners prefer to grow sets, rather than onion seeds, because sets are:

    * quick maturing
    * less prone to disease
    * able to grow in a rougher seedbed
    * happy in most sorts of soil
    * more suitable for later springs in the North

But, sets used to have a tendency to ‘bolt’.

Bolting means they go to seed, that is, instead of producing a nice big onion, they put all their energy into producing a seed head.

Modern sets are heat treated to destroy the internal flower bud, & stop bolting.

TO PLANT SETS:

* Prepare the bed by digging over & raking flat. Mix in some well rotted compost, farm mix manure into seedbedyard manure or general fertiliser.
* Place the measuring stick on the row, and plant the sets every 10cm, leaving 23 cm between the rows

set-onion-on-mark

* Push the sets into the soft earth, & bring the earth back around them, leaving just the tip showing

push-onion-in

* Watch for birds, as they like to pull the tips, so that the sets are pulled out of the ground. If the birds start to do this, cover the sets with netting, string or cotton, to keep the birds off until the sets have grown good roots. Gently press the onion sets down for the first few weeks after planting, in case they have been disturbed.

Onion Flowers

Filed under: root veg — Tags: bolt, flower, onion — TopVeg @ 3:25 pm

Snap off onion flowers as soon as they appear. If the plants flower, the
onions will become woody and unusable.

onion-flower

If the onion flowers in it’s first year it is said to ‘bolt’. Instead of
producing the onion bulb desired, the plant ‘bolts’ into maturity,
flowers, & produces seed during the summer instead of the normal root.

Mark which onions started to bolt (with a lolly stick, or anything
handy) and use these first as they won’t store well.

Onion Rust in the Vegetable Garden.

Filed under: pests&diseases — Tags: onion, rust — TopVeg @ 11:27 am

Onion Rust is caused by a fungus Puccinia allii. It is uncommon & rarely
causes significant damage to onions in the UK, unless it is being grown
next to an infected garlic crop.
SYMPTOMS
Small, reddish to dull orange, yellowy, oval-shaped spots and blotches
(pustules) develop on the leaves. They produce reddish airborne spores
in a powdery mass. These turn black later in the season. The pustules
enlarge to form a girdle around the leaves or seed heads. All plant
tissue above the girdle turns yellow and dies. If the infection is
severe, the size and quality of the onion will be reduced.
PREVENTION

    * Destroy volunteer onion, garlic and leek plants – that is any not
      planted in the garden that have grown on waste ground etc..
    * Do not grow onions on land affected by rust in the previous
      season, because onion rust overwinters on garlic and volunteer
      Allium crops
    * Grow varieties resistant to onion rust

TREATMENT

    * Remove and burn diseased leaves
    * Apply fungicides if a lot of pustules develop on the plants.
      Follow the instructions on the label.
