How deep should hoya stem be?
My mother-in-law recently gave me a hoya, and I don't believe it needs to be repotted now, but I want to be prepared for when it does. (It is in a 5.5" wide by 5" tall round pot and from the top appears to have between .5" and .75" around the main rootball, although I can see a few roots through the drainage holes in the bottom.)
Right now there are 4" of the main stem showing before the plant starts branching out with vines and leaves (i.e. from soil to vine). Is that about how it should be or should more of the stem be in the soil?
I would like to put the plant in a hanging pot, but all of the vines are on one side rather than evenly spread around like the other pictures I have seen. As it is now, I believe the pot would tip if it were hanging, plus with all the vines hanging to one side it feels like there is a lot of weight pulling against the roots.
Please let me know what you think.
