Now an update to a prior post describing Hoya sp. UT-039 and it’s twisted and deformed leaves. My reaction to this plant, that had much new growth, was to remove and destroy the deformed leaves and only keep the normal leaves in tact. I also rooted a cutting with the same leaves removed and it rooted quickly even on woody growth. New growth started quickly on the woody old stems and it seems like the flat leaves returned to the new vines but not to the old vine nodes. I will again remove the unsightly leaves in hopes of promoting more new healthy growth and report back on my findings.
I do not feel these are diseased in any way but just not so attractive. I continue to be confused about why this is happening on 50% of the new growth.
