I am happy to report my old and slow hoya pubicalyx is about to bring forth its second bloom ever. I am a little frustrated with myself after reading the many forums posts as its seems that my hoya should be huge and well growing after the twenty years that I have had it but it has been slow to perform. What do I need to do? I have repotted it with potting mix suggested. I have given it as much light as my house can give it. ( I think this may ultimately be the problem).Sad in hoya land.
