I moved mine inside the greenhouse for the winter.

Hi Seawalnut. What are the most tropical plants you're growing in Romania? That is really zone pushing at 45 degrees north!
Do you do a mix of outdoor growing and greenhouse growing?
Tropicals im keeping them in the greenhouse,guavas,somme unknown specie of inga and achacha from Costa Rica,gumuchil,sugar apples,cherimoya.
Outdoor i grow kaki,paw paws ( asimina triloba) ,american persimmons,red love apples pink, fleshed pears,wild almonds,somme walnuts that make giant nuts,cherryes ,plums,apricots,peaches ,figs ,kiwi-small cold hardy ones,paulownia-for wood,fejoa,ugni,strawberry guava and manny otthers.
