The prospect of at least 10 ° frost on Friday (and probably a lot more in our local cold hole) means that there are some of the otherwise winter-hardy crops that need extra protection - especially here where there is bare frost without snow cover. Winter leeks can be damaged by temperatures below 11-12 ° frost, which i.a. appeared last year where the leaves became slimy and the leeks gradually began to rot. Therefore, today the last 15-15 pieces have been harvested in one bed, while the other completely pore-filled bed of lack of leaves to cover it all gets a tarpaulin over instead.
More critical are the overwintering cauliflowers (the otherwise hardy Winter Aalsmeer) which were planted in August and which now have a reasonably tall stem. A few years ago, they all died in 15 ° frost by rotting on the stem at the weakest point just below all the leaves. This fall, I came across the good advice to protect the cane by covering it with leaves - which I do not have. But a duvet of old non-woven fabric must be able to do that - after which the cage also gets a tarpaulin over it. The cage may be a bit large, but is set up to protect the plants from becoming flat-masted in the event of a sudden massive snowfall after it has been covered.
