Q.Blueberry plants in winter
I live in an apartment and have a blueberry bush in a pot. Does it need to come into the apartment in the winter or can it stay out on the balcony? We face west and it is windy up on the 22nd floor. We live in Toronto, Ontario.

Toronto is considered gardening zone 6b. A rule of thumb is that container plants are exposed to a similar level of cold as in-ground plants two gardening zones lower, so you could keep plants hardy to zone 4b outside and bring others inside. Blueberries actually fall into different hardiness zones based on variety, so if you don't know the variety the best option is to bring it inside. Winter protection is another option:
