Hooked on Hoya: Valuable Growing Information

This comes to us courtesy of Carol Noel (Aloha Hoya). Many thanks Carol for giving me permission to re-print this valuable information.

The following is from notes I took while talking with David Liddle about growth habits of some hoyas. This is not meant to be a "how you should grow your hoyas" but how the hoyas grow in the wild. Remember that hoyas basically grow where and how they can grab a foothold in nature: from crotches of trees where leaf litter accumulates, in a clump of moss on a branch etc. These growing condition are how David has found the hoyas he has collected.
