Hi everyone this is my first post on gardenweb, hoping to get some advice on caladiums. I have never grown them before.

Shade vs Part shade

For the white caladiums (I have Moonlight) does more sun cause the leaves to be more pure white thus less green or is it the other way around? I want to have pure white or as close as possible. Also same question about fannie munson which is solid pink sometimes and other times there is a large dark green border. Will more sun produce mostly pink?

Soil Acidity

I have also read that acidic soil produces darker colors. Will acidic soil make the green more pronounced on the white varieties?

Any advice would be appreciated.
