Muricata is a very touchy vine , put it outside in shade as soon as possible . All of my caapi do great with fast growth no issues or complaints .
I have to baby my muricata , put it this way , it doesn't take clones well , I had to air layer it for a year and a half to get a clone and baby that one as well , large pots do help , but being outdoors with the wind blowing it and natural light , filtered , part sun part shade , I actually never let a lot of direct light on it , it's in the semi shady area of outdoors all day , in the winter it need s a part sun light direct light window for about min 4 hours a day
I feed it a flowering fert about twice a year nothing crazy , I leave it alone , I don't take cuttings , leaves , nada .
I harvest the leaves it drops or branches that die and try to air layer the vine for clones , it is not my bulk vine to be sure .
I mainly grow it now for novelty because it grows so sensitively . I'm ok with that , those silver leaves and the addition of its minimal vine in my novelty home brews . It's enough but it's not my bulk vine as I said .
Just nurture it with as much 'leaving it alone ' as possible in a spot you won't move much were it won't get sunburned an it does ok with watering. I don't over water I really don't underwater or let it dry out either , but never ever over over water in my case . I've almost lost it a couple time s. Now I leave it be
