H. calycina - black spot? overwatering? too cold?
Hi all - I am just not having any luck keeping some of my hoyas alive!!
This time its my calycina... my favourite furry leaved critter :(
Last week I noticed that one of the stems had dried right through - now the leaves at the bottom of the cutting have their stems drying out. The whole cutting also looks like its drying out.
What could be causing this? I had some black spot on a few of my other hoyas (it has been very humid this winter) which I have treated successfully. A few of my warm hoyas had some leaves drop off which stopped after I took them inside - I have never seen this though!
I dont think I am overwatering them - I let the soil completely dry out between waterings and I dont mist them in winter (as I said, its been humid enough!!)
Any ideas? Thank you!!
