I'm afraid I know next to nothing about growing orange trees, Jomichele, but here in northern Italy, quite a few people grow Kumquats, which are a close relative, delicious to eat (peel and all), beautiful to look at, and easily raised in big containers. I believe they are generally about 5-6 years old before they give a really good crop. In California, they will get enough sunshine to do really well.

I need advice on growing Articokes? I want to grow it in a container. I am in Southern California. PLEASE HELP, Thanks!

Jomichele you would be better asking a separate question re artichokes so that everyone sees it and do you man globe or Jerusalem artichokes?

If you want to follow this question, do it here, Jomichele. I shall copy my answer here as well.
Yes, you will need to feed it with citrus food, but not to start with, I think. It depends how big a plant you start with. I'd go for as big as you can afford to buy. The supplier will be able to tell you better than I can how to look after it. I don't think it grows very big at all. I have seen them here about 9', but I'm sure they grow bigger.

THANKS, Moon growe, I didn't know that.

Ok, I am beginning to understand. THANKS again, Getinna!
