What are these bumps all over the new growth?
My cissus discolor has been popping off a crazy amount of growth lately. Was checking in on her new leaves and a handful have these bumps all over them…what is this?
Edit: some more info - I don’t believe there are any pests, its got systemic in the soil and I regularly wipe down the leaves with captain jacks.
After doing some reading it says that this type of plant does this as a stress response to a pest or a disease? #GregGang

@AroidApothecary hi there what a beautiful plant. So your postcard my eye because I haven’t seen that before and it is most curious to me. I did do a Google search to see if there was anything specific for that and I also read it through an AI software that can be helpful sometimes in ascertaining what plant diseases there may be. I was surprised that it said that your plant looked healthy because those bumps don’t look normal. Are they raised or elevated? Look at the most prudent course of action if it were my plan would be to sterilize some shears with rubbing alcohol to prevent the spread of any pathogens and removing those leaves. It would not hurt to go ahead and treat the plant with a copper base fungicide that you spray on the foliage. If you think that the conditions around the plant could use better lip ventilation that might indicate it might be a fungal issue. This would also further justify the application of a fungicide as a matter prudence. Mate fungal pathogens are soil born and they attach the foliage when it’s wet. If you don’t have a top dressing all over the soil to create a physical barrier between any fungus in the foliage that can create an environment that is conducive to an outbreak. Also your watering technique can have an impact on this. It’s best to use a watering can with a long narrow spout that allows you to have some precision when you’re watering and not splash foliage on the leaves. Yeah if you don’t have a physical barrier on the soil and if you have reason to believe that maybe some water splashed onto the leaves or has gotten on the leaves that would have given the fungal spores a place to attach on the leaves try making some adjustments on how you care for the plant and see if that solves the problem if you continue to have problem At least you know that you’ve done what you need to be doing to illuminate fungus as a possible issues. Some plants get spots on them like this like rubber tree plants and those are normal but I don’t think this is it. Additionally when I first looked at it I thought it might be a pest. Begonias can be fussy plants so I like to use the systemic pesticide that’s applied to the soil in last for eight months to keep this from happening. If it is a pest on the plant you can spray them off you know using a high stream of water just make sure you let the foliage dry in front of the fan or ventilation said it doesn’t cause a secondary fungal issue you can apply neem oil to the surface and that should help keep them away but it really depends on the pest. It seems like the planters otherwise OK so if you start with removing the leaves and inspecting the plant for pests other way and other areas and using a fungicide creating a physical bear in the soil etc I think you’ll be good for now just be sure to watch the plan of monitor for any future developments
How do the leaves feel when you touch them? Can the growth be wiped off, or is it part of the leaf itself? Judging by the look, it might be a fungal infection. Neem oil or your preferred fungicide at night to avoid leaf burn should help. Depending on your answers to the questions above, it could also be stress-induced adaptation as you proposed. I'm curious as to what it might be. I've never seen this type of growth on a begonia. Good luck and keep us posted!
It looks like this is a cissus discolor, which is not actually a begonia, though it's called the rex begonia vine usually. I found this post about the bumps, https://homespursuit.com/little-lumps-on-cissus-discolor-causes-and-solutions/. Hopefully this helps. I would take the advice given above for treating for sure.
