I didn’t actually think the Hoya retusa I bought was going to survive. When I bought it, the leaves were shriveling up and the vines looked like they were going to dry out. I repotted it, changed the soil and gave it light from my south facing window and it sprung to life! Now the vines are attaching themselves to everything they can grab, including the sting I used to hang it up.
I keep forgetting to water this Hoya, so the soil is bone dry for maybe a week or two before I water again. I guess this one can handle that. It’s thriving on neglect.
