After being involved in a few threads dealing with Citrus being grown indoors I think it is time for someone to ask some open questions and let all of you join in and discuss the following.. How many Citrus and what types of Citrus are true grown from seed? Why is it that Citrus grown indoors have a propensity to not produce fruit? Why is high humidity a rather serious, potentially harmful consequence to growing Citrus indoors? What is the difference between a wholesale nursery and a retail nursery for buying Citrus? Why is it that Citrus from US East Coast nurseries or nurseries East of the Rocky Mountains cannot ship Citrus into California? What are some nursery sources for Citrus in Canada? Why are California nurseries hesitant to ship Citrus into Canada? Which Citrus can be grown outdoors in the ground or grown outdoors in a container in Canada? Which Citrus can be grown indoors and still produce fruit in Canada? What prerequisites must apply in order for the tree to set fruit? The above questions can be expanded upon as I do not plan to be the moderator for this thread. I may come back in and post some of my own views at a later date. For now, I think a general and perhaps inclusive thread dealing with Citrus, being grown principally in Canada and elsewhere also, may be something worthwhile for us to openly discuss.
