Cauliflower

I am looking for varieties of cauliflower which, at the stage when they are not yet planting flowers, are able to survive our winter under non-woven foil or in a foil tunnel (in cold bed). Some will perhaps withstand such protected -15 ° C. I'm primarily concerned with the names of those varieties (I read that some are of Japanese provenance) and only then where to get the seeds.
Thank you in advance for any information.

It's very interesting to me. I would like to find more vegetables that can be planted in fall, generally. Too bad it is a bit late to start the Galleon. It would be great to have a cole crop that can be planted just after garlic harvest here.

[media][media][media][/media][/media][/media]On the Czech website Zahrada.cz, a gardener announced experiments with growing cauliflower over the winter. He wrote:
„I sow the first half of the plants today, ie 25.7., The second half 8-10. August. In addition to the folio, a pair of dozens of plants will go out as well. The comparison will consist of a comparison of varieties, a comparison of two sowing terms, a comparison of foliage / outdoor and a comparison of textile cover / non-cover. Plus, I'll probably try to sow some very early cauliflower directly so that it grows + -like rapeseed by winter. And the last comparison will be the planting of professional seedlings of super-early cauliflower from the first available seedling from the Netherlands, ie sometimes about 8-9. week 2021.“
This inspired me to also try growing cauliflower over the winter, similar experiments with different methods of protection and similar pre-growing dates.
That's why I'm looking for frost-resistant cauliflower seeds. In our country, such a variety was commonly available (Arktur), but the seed company SEMO excluded it from the range because there was little interest in the seeds. I like that Galleon, but so far I haven't found a company in GB that sells these seeds.

PS.: I will still try lettuce (two varieties) and head kale cabbage Arkta (picture).

Look for other cauliflower seeds that are for spring harvest, or over-wintering.

Thank you Nan for the tips on winter cauliflower. I received from a friend the seeds of five frost-resistant cauliflowers and one broccoli (broccoli can fully stay in the bed for five years). I planted some of the seeds yesterday. One of those cauliflowers is Galleon. I will probably create threads here on Tomatojunctio and also on Tomatovile, in which I will inform you how I manage to implement this project of winter vegetables.

I have prepared three flower beds for growing winter vegetables.
Flower bed 1
The plants on the left half of the bed will be covered with a standard 19 g / m2 non-woven fabric in winter. On the right half I will use a fabric of 50 g / m2, which is intended, among other things, to protect plants from frost. Winter onions (Augusta, Hiberna and Senshyu) will be planted in the rows on the side. Brasicas will be planted on the two middle rows, always in pairs, so that the skin can be compared to which textile protects the plants.
Flower bed 2
Today I planted cauliflowers in this bed from the sowing on August 7, 2020- Walcheren Winter 5 (5 ks), Aalsmeer (5), Galeon (5), Celebrity (5) a Winter Roscoff (5). Next week I'll put Nine Star Perennial Broccoli (4) here. Due to the pests (Cabbage White and Cabbage Moth), I temporarily covered the planted cauliflowers with a curtain, which will be there for about a month. Then I cover the flowerbed with one of the tunnels (I have them now in the autumn brasicas) and the one above them will remain until spring. As soon as it starts to freeze, I will insulate the tunnel with a non-woven fabric 50 g / m2. I probably won't open the tunnel during the winter. I have watered with a pipe placed in the middle of the flower bed.
Flower bed 3
Here I will gradually plant the remaining Brassicas - Arkta cabbage, Pylon F1 cabbage, Limba and Steel broccoli and also some winter salads - Humil, Apollo, Ledano and King of May. I move the second tunnel to the flower bed. I won't sow salads until tomorrow - there's plenty of time yet.
Flower bed 4
I have not prepared this bed yet, there will only be salads covered with non-woven fabric 19 g / m2.
I would just like to add that the temperature and humidity in the tunnel (even outside) will be measured throughout the winter at a height of about 20 cm above the ground. Surely these will be important data for deciding how to grow Brassicas in the coming years.

This is what my beds of brassicas look like now. I already covered them.

Impressive setup. Is it easy to uncover your plants and to put the cover back on?

In Figures 2 and 3, the tunnels are unfolded. Unfolding the tunnel is a matter of one to two minutes. The metal profiles with which the tunnel is loaded on its side are removed and the whole tunnel is tilted. I would also like to draw attention to the meteorological booth in the middle of the higher tunnel in which I will measure temperature and humidity throughout the winter. For comparison, there will be a second booth outside the tunnels.

That's a great set up. You have some very happy plants there! That's smart to have weather data collected both inside and outside of the tunnels.

Today I went to see the garden. Really just look. I uncovered both tunnels and also a part of the flowerbed covered with non-woven foils. I already knew from last week that snails began to enjoy my vegetables. But I just opened the high tunnel and took some pictures to see how it would develop. It is true that there has been no further damage to cauliflower since November 5, probably because the temperatures outside have dropped to freezing and the snails are active from + 5 ° C. It's worse in the lower tunnel, where I found out today that all the planted salads are gone. All I have left is to wish those snails a good digestion. Snails were also eaten on the flowerbed covered with non-woven fabrics of various weights, but only on the old one, which was covered with 50 g / m2 fabrics. I explain this by saying that the heavier foil still protects more from the cold, so the snails had nice, warm sweat under it. I won't do anything about it anymore, but I have to prepare for spring, for fighting snails. Onions and spinach are all right.

I just cut broccoli yesterday, Four of the six plants looked ready. The flavor was excellent but heads were still smallish. I have 6 cauliflower and 6 cabbage as well. They have been covered with AG19 tunnel since planting, until a few days ago. They need to be covered here to protect from cabbage moths. That much I have learned, at least. It has been down to 30F a few times, but not much below, and has generally been pretty warm here. This bed only gets morning sun, and house shade after that, during the autumn. They're healthy but they need more sun. I don't think this bed is a good match for crops this time of year. I figured I would take some pics for comparison to your similar setup, since these might be harvested soon.

It is supposed to get a bit colder here and down to 23F in a few nights. I guess I was planning to pick these but I honestly don't know what to expect if I don't. I will cover them back up if I don't, but it is just AG19 so I won't expect much.

2 broccoli (fallen since other 4 removed yesterday), 6 cauliflower, 6 cabbage, transplants bought, covered, and drip tape irrigated occasionally since late August with otherwise no tending given. The sun here, now, is only about 7:30 to 10 am. I haven't seen any snails but there is some minor holing of leaves that might have been snails.

edit Pics just taken at 945a and the sun is about done for the day already.

I was in the garden yesterday. It's still raining, there's mud everywhere, so I just opened the cauliflower cover and took a picture. I also downloaded the temperatures measured over the last twenty days to my computer. Only four nights were cold, the minimum temperature was -5.4 ° C. The plants look a bit different than in the previous photos. They didn't grow much, only the drawing on their leaves is more pronounced. I don't know if it's right or missing something them. According to forecasts, the real winter will not start until after the Christmas holidays. All I have to do is wait, watch it and hope it works out.

Yesterday I went to look at the garden after a long time. So far, winter is warm rather than cold in our country. Two or three centimeters of snow fell and most of it was melting. My cauliflower in the tunnel is still in great shape. Meteorologists report that it should soon be colder, temperatures at night up to -15 ° C, which would mean three degrees more in the tunnel. When I downloaded data to a computer yesterday, I accidentally downloaded a temperature graph for a completely different period from the data logger I measure in the tunnel, so the data in the picture is only from the outside.

Wow, that's 5F. I sure hope your caulis hold up. Mine are bigger and they seemed to take back to back nights of 23F (-5C) ok. A bit droopy but no burn that I could see.
