Hoya with leprosy?

banannasAugust 19, 2011

Hi all,

It has been a wild summer of family reunions, white water rafting, presenting my research at conferences, falling for a new guy and travel here there and everywhere. So sorry for being out of contact. Now that I have been home for a few days and have started to unpack, buy groceries and tend to my plants I have noticed some funky leaves on my unidentified but suspected carnosa. I did find some mealies on it and took them to task with some physan 20 and a q-tip. They look so different than the others and this abnormality isn't limited to just one vine. Is there something wrong with it? and if so what should I do?



Here are some side by side comparisons of the normal leaves

This is what happens to a new leaf if mealies are present while it is developing. The fact that they (mealies) are sucking fluids from the leaf means that the resulting scar tissue, however minute will result in leaf deformity.

Hm, that IS odd. Could be mealy damage, but I'd think if they did that much damage, it would be so obviously infested, you'd be tossing it out. It almost looks like something like a chemical got "oversprayed" onto it. Is that possible? Personally, I would cut off all the vines with the gnarly growth and see if the new ones that are generated by the pruning are ok.

Yeah I only found six on the whole plant. I just went over it again and can't find any more (mealies). I'll try to keep a better eye on it. In a way I think that they look kind of cool I just was worried that it was disease that could spread to the rest of the plant or my others but now I may just leave it :) Thanks for the advice Denis and Mike!!!

I find it's not so much the adult mealies that cause this damage it's the tiny crawlers that attack the leaves while they are just starting to develop. I have a big Hoya carnosa that periodically gets mealy outbreaks and if I don't catch it on time the new leaves end up just like the ones in your photos.
