Elena ,, it is strange when you get big plant that does nothing ,
Rick that tall bok choy was looking okay the last time I looked , it has taken upper 20's several times , The tall choy likes a better earth soil than my ground , The ones that were being eaten were growing new leaves that looked pretty good after the couple of frosts It was 24 degrees last night , I will look tomorrow and see what is ,
I have that white stuff on my cars also ,, Permafrost ! ..
