Karen, my multiflora does something similar - yellowing leaves and dropping them while the whole plant looks good and flowers! And var. kerrii did the same too, it is gone now. With kerrii I can at least think that I repotted it at the end of summer and it dried for some reason? Multiflora stays in water all the time. But the house is pretty dry now, with 30% humidity at best, usually less. Can it be your problem too? Did you figure out what was going on with the previous yellowing rpoblem? Have you checked the roots? (I hate it and usually do it as last reserve).

Hi Vera,

I don't think it's dryness, they're all on pebble trays, & among those that are doing well, there's even new growth (& you being in Jersey, know it got kind of cold lately). I'd guess that dryness would affect more than a few.

No, I never did figure out what happened to my other one with severe yellowing (alleged Coronaria), but that one's gone.

Well I got kinda crazy abt the Shephardii & did turn it out to look. The mix was weird, so I replaced it. I started using Coir last yr., most of the Hoyas all loved it. Maybe I had too much coir in the Shepardhii, the mix was sort of very dry & dusty crumbly, reminiscent of sawdust, strange. So it's had all new mix, a good watering & now I've just got to give it time.

The Pubicalyx that's having a bit of this, was a troublesome one abt a yr. ago. I think I had replaced its mix then & it stabilized for the yr., now it just has that one yellowing leaf, which interestingly, had been holding on tight, 'til I just pulled it off.

As to the Kerrii, my original is fine, my rooted cuttings, so, so, still one yellowing leaf, otherwise its other growth & the mix look OK, it's my mix & was only potted up in summer, so I think that's OK. Perplexing ... & thanks for asking.
