Congrats, it´s looking beautiful!
Personally Ive only grown caapi, or better said, i´ve only planted caapi in tropical places, where I didn´t have to do anything except let time pass. Not sure what kind of climate you have there, and if you´re keeping it indoor, if you have good sunlight, etc..
Check the ethnobotanical garden subforum, maybe you find some threads of interest.
Good luck!
