Hey guys I’m super excited to be here I have a delonix regia which has been growing relatively well for about 5months however I haven’t been able to fight it’s shedding of lower leaves I see in other threads this is particularly normal but in other they seem to have so much more foliage under but mine doesn’t seem to be so. I live in the Uk, London specifically and I understand this is super hard with my conditions. Its currently in a mini indoor greenhouse next to the window with a little fan to circulate air enough but not move the tree too much and humidity it’s controlled between 60-70% however this does dip sometimes before 55. I supply the tree with fertilizer once every 12 days and as I’ve mentioned it’s growing really fast and well but the foliage on the bottom is falling. If this is just a natural process then that’s fine but I’m just looking any reassurance or tips to help it thrive better than it. Also any ideas on when i should top the tree would be great as im not sure if I’m supposed to let it grow more or trim for wider growth
