I ’m experimenting with timing , growing the right varieties , and using an unwarmed greenhouse .
So how cold does it get here for our unheated winter greenhouse ?
The coldest it get here is -20C/-4F however it often goes above 0C/32F during the winter creating chance to harvest winter veggies . You always want to ensure you harvest veggies after they ’ve thawed out otherwise they ’ll finish up mushy .
Our winter veggies go through freezing and thawing for a lot of the wintertime .
After thawing winter vegetables will perk back up ! See the nose candy in the background ?
I ’m also find out a destiny by notice , some crop I ’ve been pass on in the ground to see their cold tolerance threshold .
For example our baby bok choi was happy until the death of December when it reached -10C/14F.
