Normally there is no big Need for defoilating an outdoor Plant, because the Sunlight has more power to penetrate than Indoors. What you can do is to give her some "light tunnels". that means take only some large leaves away and try to make tunnels into the Plant. But i think your Girl has no Need for it. She Looks Wonderful. and if some buds are not mature, just let those unmature ones hang longer on your " tree". You can softly bind some strings at the Ends of the branches and pull the branches , to open the plant. Well that my 50 Cents to your Plant. Iam growing every year some " bigass" Plants and i mostly do only some tunnels. or if she grows very desne try to spread her with the strings.
I have more the Problem to Keep her stable to the Wind and rain... and i give her in later autumn a " Cage" to lean on and some strips to fix her agains heavy wind. And she gets atransparent Roof to, against the heavy rain in late autums.
