In My Seed Box For 2022 - Spring Onions

  


In previous years I have done really well with Spring onions, I have two or three with my sandwich most lunchtimes. A note has been added to my Sowing & Planting Plan for 2022 so I can get Spring Onions going a month earlier than previous years.

The life expectancy of Onion seeds is 2 - 4 years, and most suppliers have a two year gap between packed and sow by date.

All but the sow by 2021 seeds will be removed from the Seed Box this year.   

My sister treated me to a couple of packs of Lidl - De Barletta Spring onions and I bought 3 more packs in April when I went shopping.

These have sow dates between February - April and August - November and are Frost-Resistant for harvest in spring and summer. 

Germination is 15 - 20 days and soil temperature needs to be between 8 - 10C  No seed count but pack say enough for 10m of sowing.   
   

New for 2022 - Lilia - 550 Seeds -  £2.49  - 43 79 38 - Dobies  

Lilia is a dual-purpose Italian variety with a robust flavour. Dark pinky/purple base, tapering to dark green leaves Spring Onion Lilia is best grown as a salad onion. Its eye-catching dark green leaves and a shiny, intense red inner core make a great addition to a summer salad. Plants can also be grown as a maincrop, storing bulb onion. When fully mature it shows off its defined red and white inner rings. 

Sow March-July 

For salads, best sown in broad drills sparingly April - July, into finely raked, firm soil at a depth of 10mm in rows 300mm apart. (Germination 14 - 21 days). No thinning necessary. Bulbs will be quite large if left to mature. Sow a pinch of seeds regularly for continuous production. 

For bulb onions best sown 3-4 seeds per small pot in a propagator or greenhouse during march April at approx. 15C eventually planting outside. 

Best grown in ground that has been manured the previous autumn. Water freely in dry weather. 

Harvest June-October.

Sowing Plan for 2022

In 2017 spring onions were grown in vending machine cups in tray modules and transplanted into the onion beds plant membrane, but white rot got a few and the rest had to be harvested early or disposed off.

In 2018 I tried to grow them in cut down square flower buckets but the results weren't very good, saying that the Spring was unnaturally warm and dry.

From 2020 a return to growing in vending machine cups in tray modules and transplanted into the onion beds plant membrane, 



Looking at the back of the seed packets, yes I do read them! What I find interesting is the different guidance provided by different seed companies for the same variety of plant. for example, looking at Ishikura Spring Onions from Wilko, Thompson & Morgan & Mr Fothergill




Sowing Outdoors

Mar - May ~ Thompson & Morgan
Mar - Jun ~ Wilko
Mar - July ~ Mr Fothergills

Frequency of Sowing

Wilko &  Mr Fothergills both suggest every 2 - 3 weeks for a continuous supply throughout the summer, interestingly Thompson & Morgan advice is that "The long harvest period means one sowing lasts the whole season!" which is kind of mad as there harvest period is shorter than both Wilko & Mr Fothergills ! Thompson & Morgan also states "Can be harvested pencil-thin or thinner, or left to mature to carrot size" although they don't state what kind of carrot.  

Thinning

Wilko & Mr Fothergills both suggest no thinning is required whereas Thompson & Morgan state it is!

Harvesting

May - Oct ~ Wilko
Jun -  Sep ~ Thompson & Morgan
May - Oct ~ Mr Fothergills

Germination 

Wilko &  Mr Fothergills both state 14 - 21 days and Thompson & Morgan provides no information on germination, I have seen this missing on quite a lot of their packs and it's something I'm and I guess most other gardeners are actually quite interested in.

I know that like Structural Engineers, if you get four or five gardeners together and ask them a question you are likely to get three different answers but until I see what other suppliers of Ishikura Spring Onions have to say, I think I will ignore T&M and go with the guidance from Wilko & Mr Fothergill.
