WebSep 10, 2024 · Stick with the higher ratio nitrogen fertilizers unless your tree is determined to be deficient in potassium or phosphorus (soil test). N-P-K rates of 18-5-9, 27-3-3, or 16-4-8 are good bets. Not all trees are alike and conifers rarely need high rates of fertilizer so you might want to skip applications or stop feeding after a year. WebSep 2, 2024 · We motivate this with findings that while stem to crown biomass ratio changes over the course of a tree’s life span, crown shape is relatively stable and crown size remains strongly correlated to stem girth (Harja et al. 2012, Antin et al. 2013), and that Mäkelä and Sievänen (1992) found a power law relation as a result from an optimization study of …
