A few of my plants are getting quite large and my question is......if I have a tall plant, like a foot and a half, should I try and focus the light on the top of the plant with the newer growth or more towards the bottom with the soil, roots, etc? I have a philodendron that has a REALLY long kind of.....skinny tree bark part that's like a third of the plant. It has no leaves, it's just curvy and like hard and rigid. Then at the top is the new growth and it's what I know a philodendron to to typically be. Will that newer area area eventually harden up like the lower area? Also will most definitely be getting her situated onto a moss pole now that she's not.....being a tree or whatever and is actually showing some aerial roots
