Why do you want them to grow more roots? They look very healthy!

What fertilizer are you giving them? H. pubicalyx 'Pink Silver' and H. carnosa both 'seem' to like growing in lower light than full smack on sun...and they enjoy growing drier more than wetter. I would feed them a balanced fertilizer with a higher middle number than the other two numbers. BLOOM fertilizers are good. Instead of once a month application, I would give the fertilizer 1/2 strength every second time you water. ALL hoyas enjoy aircirculation!!! not stuffy rooms. Hs. carnosa and pubicalyx are good ones to grow cool (I once saw a HUGE H. carnosa growing in an abandoned house in Taos New Mexico in the dead of winter. I don't think it had been watered in a LONG time.... Not a good way to grow them, but they do take cool/cold temps better than most.

I hope this helps....

Thanks for the advice Carol. I'll try the bloom fertilizer before I try anything else but I have some newbies coming and I might try her bark on a few of them to see if that gives me blooms. I thought one needed a rootbound plant in order for them to bloom. That is why I"m concerned that they haven't produced mass amounts of root at this point in time. I was incorrect on the dates too. I got the biggest plant (pink silver) in 89' so she is only about 23 years old but she has done well for me.

I have an office spot that is next to a window so my plants would get a good amount of sun in the wintertime. Unfortunately I am also right under the heating and airconditioning vent so there are often cold bursts of air summer and winter there. Will hoya (say a tricolor carnosa) do well here?

Thanks again!
Coralee
