My winter onions look great today. Next winter I will grow the whole bed of these three varieties. Other gardeners have not even planted a planting and sowing (the coldest April since 1941) and I will be harvesting fresh onions in a moment.

They do look great. I like the idea of being able to plant onions in the fall and then harvesting next summer.

Update on onions here is interesting. By mid-May, the local Jung's garden center usually has a 2 for 1 special on onion plants. Won't happen this year. Out of at least 10 varieties available, only 3 crates still had a few bundles. Have never seen that before in the nearly 30 years that the store has been there.

At home the Redwing were the quickest to recover while Patterson sulked for awhile. Now some Patterson are almost a foot tall. With 6 weeks yet before bulbing there is a promise of some huge bulbs again this year.

Four days ago, planted onions which most would think might be best just for scallions. They were started very thick in March. Varieties were Ailsa Craig and Blush. All only had one leaf and maximum size was 6". They were never trimmed and had to be separated in water to untangle the roots. My friend's methods go against most rules but she gets super results. Theory is that they just need a month of growth before the first day of summer triggers bulbing. Unlike the Dixondale trimmed plants which took several weeks to show growth, these plants all standing tall after 4 days.

I planted my onion one week ago. They were about 5mm thick, which is not bad, I think any thicker than that and they are going to restart slower.

I have to put them so very late because of the allium leaf miner which is completely destroying all allium crops over here, I even lost a few garlics which should not be affected (they say), the ones that don't show the symptoms (but are still at least bit affected) don't really have the same growth they could have had. The miner has two cycles, and it should stop flying in the middle of may. I think I will plant garlic earlier next year, so that it's older when the attack happens, that seems to make the difference (but I am afraid not to catch the autumn cycle).

1. I am extremely satisfied with the harvest of winter onions. They survived frosts between ten and twelve ° C under nonwovens. The best are the common Czech varieties Hiberna and Augusta, seeds for a few crowns. I bought Kelsae seeds over the internet, it was four times more expensive, and if I didn't want to buy them, I would have to propagate the seeds. The picture next to it is what's left of the cauliflower. The flowers on the cauliflowers are starting to bloom so I wrapped them in a curtain and I will pollinate by hand.
2. In the second picture, seedlings of large onion are planted in a flower bed. They're not very big yet, but I hope it gets better.

Hi all, I've been away for a bit. Got Covid from my daughter so I had to quarantine myself for 2 weeks plus we had crummy weather. I finally planted some of my onions in the past week. The ones I grew from seed had a really good root system. I was able to pull the entire block out gently. The cells are 5" long. The trays I used are these: https://www.greenhousemegastore.com/dee ... plug-trays
@ponyexpress, does that 5" plug tray fit into a standard flat tray to catch drainage? This 5" one looks like a great alternative to how I've been growing onions and scallions from seed. Going to be trying leeks for the first time this fall and these look like they'd be handy.

As predicted earlier, the large Patterson plants have bolted on at least 25% of the total and still may be more. Their bulbs will not be stored very long. Om the other hand, not a single Redwing has bolted.

Here are the 'french shallot' 2 days ago. Not quite as thick as the tulip stem. Transplanted from cell packs with no trimming, but they took a long time to start to stand upright, probably due to the major change from greenhouse living. I thought they may lose a leaf after all but this morning they're looking their best ever, so perhaps not. Bit of snow left them perky. Get on with it! :)

@ddsack we are back to normal thank goodness. For such a rare event, the good thing is it'll probably be a long time before we see that again!

I can't say enough good things about Patterson. Not this year's crop but last year. We are now in mid-June and there are still a dozen bulbs from last year which have not sprouted. That's 10 months since harvest and still firm. They are outlasting shallots! Not overly happy with the ones growing now. Still nipping off flower stalks. Planning to chew out Dixondale for their first major error with me in almost 40 years.

My experiment with growing onions over the winter is definitely coming to an end. Today I plucked three onions to consider. Each of them weighed about 20 dkg. Of the forty planted seedlings, only two bulbs went into bloom.
Basic information about this project:
Sowing of three varieties of Augusta, Hiberna and Senshyu at home in 200 ml cups on August 3, 2020. On October 5, seedlings about 5 mm thick were planted on a flower bed in the holes in a black mulching cloth. During the winter, a non-woven white fabric was placed on them so that it did not lie directly on the plants, but was about 20 cm above them. The biggest frost was - 15 ° C. From mid-May, I harvested fresh onions for raw use. They were excellent in taste.

Sent message to Dixonale concerning the extra-large Patterson plants and that many are bolting. Almost had to laugh at the generic explanation for bolting. Everything was blamed on conditions as if it were the gardener's fault. Not once was the size of the plant or set. My first reaction was to fire right back with the facts but since this is the first bobble in over 30 years, I let it lay. For certain, I will be watching them close next year.

Yes, the trays do fit within the standard 1020 trays. I’m trying to remember if I used my trays with them or not? The only drawback of the 5” trays is that they are very heavy when fully loaded.

All of my onions are bulbing now. Comparing the onions that I grew from seeds with the Dixondale plants, I think I can say that I finally equaled them. Had to start the seeds in January to give them enough time to grow.

My Copra onions from last year are still intact in storage with only a few that sprouted. I have heard good things about Patterson so I’m looking forward to testing their storage qualities.

At the community garden, my onion plants look far better than everyone else. I think this is because I planted them in late April after we had periods of cold weather. My plants were in 5” trays in the house at night but outside during the day. I think that helped them a lot. The other thing is the trays were filled with compost, not potting soil.
