So I planted my sango kaku 1 year ago in May 2011. There were new shoots at that time. Fast forward to spring and summer 2012 and, not only has it not grown new shoots, it has shrunk (ie. in the form of diebacks, though thankfully not a lot). Though I'll admit there were a few (very minimal) new shoots scattered around the base of the crown. The top of the crown had the most of the diebacks and no new growth. Why is this? Is it because I didn't add fertilizer this year whereas when I bought it there was fertilizer already added? Is it because it takes a while for the roots to establish before new growth can occur? Or is it because there's too much nutrient competition from the companion plants around the base of the tree (mind you, our soil is pretty high in organics and is consistently moist)? Another thing, the leaves at the ends/tips of the tree are pretty burnt and crispy-ish whereas the leaves inside are fine. Is it because water and nutrients aren't able to reach to the ends of the branches or is it because the sun is damaging to the leaves on the outside while the leaves in the inside are sheltered?
