Ceylon Cinnamon
 

My brother got a couple of small trees, but neither of are able to find out what sort of soil that these particular trees prefer. His soil PH is around 7.0 - 7.5, so we're working on making it neutral, but maybe this would be a mistake, as this particular tree may prefer it? Anyone know? Cinnamomum Zeylanicum, is the botanical name. It's the variety from Sri Lanka. Thanks
