I use Woodace and Miracid this year but not much improvement. I haven't tried to combine Woodace and Growbetter chicken manure. Seem like you use alot of Woodace for your trees.Did you try this Woodace ?https://www.lebanonturf.com/products/items/2256323/index.aspx
I have been using it combined with organic fertilizer for few years with good result. My California junipers have been growing like the weeds !
