Thank you, i have heard they like to be pot bound but when is pot bound good and when is it to pot bound.I have a Hoya compacta variagata, it is in a small pot & is definitely pot bound the roots are visible on the top of the pot.Every bone in my body wants to re-pot it,i don't know what size to go up to.I have never re-potted any of my Hoya's they are all in the original pots and soil, i haven't had any problems.They are outside but i will only let them stay out in rain storms if it's been dry.We have had a few days of rain after a month of dry 90 degree temps,i left them out.They are calling for rain again tonight my Hoya's will spend the night in their winter home in the bay window out of the rain.
I use a chunky orchid mix with either a good rich soil or peat added.Depending on what i'm potting i add more bark for drainage in my succulents,peat if the plant like to be moist but not soggy and a good soil for other plants then some i don't add anything.
I'm not sure what this hoya prefer's??
Sorry this one is really out of focus
Have a wonderful day
