I have question, since my Calamondin trees' leaves are pointing downwards, I went for help also in the GardenWeb forums where I was tried to be convinced that citruses can't be grown as indoor containerized plants, and they can only be succesfuly grown only outside in full sun. Is this true? (I hope not)
I have a southern windowsill, where in summer months I get about 6 hours of direct sunlight a day. I live in an apartment, so I don't have the ability to move my plants outside, plus with Lithuania's climate, when summer night temperatures often fall below 15C (a minimum necessary temperature for the growing season of citruses) I can't imagine any vegetative growth happening.
Should I say goodbye to citruses and give up?

My calamondin stayed on the balcony of my flat last winter. There was no problem with overwintering! The temperature was in range +10 +18 C with high humidity. The window has the eastern-southern orientation.

Citrus are grown as indoor plants by the 1000's all over the world, day in and day out. Our friend at GW should know better. - Millet (901-)
