Carcinoma? Do you maybe mean "carnosa"?

I would think an east facing window would be getting morning sun and if so, that should be ok. Mine get that outdoors and are fine. Let your plant dry out between waterings, meaning that you should check it every other day or so by sticking your finger into the soil and if it feels dry about an inch or so down below the surface, then it is probably time to water. I have the Hoya carnosa Krimson Princess (variegated) and the Hoya carnosa Krimson Queen (tri-color)and they both can get pink leaves at first so thats ok. There are quite a few carnosa cultivars so I am not sure which one you have, but the care for them is all pretty much the same!

Don't cut off the leafless vines, they will get leaves and eventually will bloom from them when your plant matures.

Carnosa is a tough plant and can be grown just about anywhere, but east sun is really ideal. A new leaf won't grow back where a leaf was cut off, but it's ok to remove damaged leaves - it won't hurt anything. You can fertilize your Hoya during the growing season, which is typically early spring (March or so) until around October. If you want to encourage flowers, a bloom boosting fertilizer is best (high middle number...), but just plain old Miracle Grow would be ok to encourage new growth. Most Hoyas will bloom in their own time if given the right conditions whether you use bloom fertilizer or not.

Denise, I had to cut back and remove alot of old leaves and growth from some sun and frost damaged hoyas_carnosa, compacta, and pubicalyx- and their ARE leaves growing back from those nodes - sometimes just one, sometimes both leaves. I was surprised to see this myself - this is happening on the older vines, not new ones.

I am finding the same thing with some of my hoyas - although I haven't seen that occur on any of my carnosas. I have seen several of my plants develop leaves on old woody vines that have been "bald" for years - I think they must be exceptionally happy this year!

As for the advice everyone has given to bbgirl81, I think it is excellent! Your carnosa should really enjoy that early morning sun.
