Btw, do not feel bad at how your schefflera looks like..it is eons better looking than my plant nowadays
Mine is overdue for a good pruning..since it is already like ready to run away from its container
and this is a plant already being grown outside. A case of too much shade from the shadow of our house and shadow from the trees once they are awake..then getting pan fried in the afternoon when there is intense afternoon sun
So in many ways, your plant is awesome to my eyes.
