What nutrient balance should I aim for in my bonsai fertilizer?
I'm currently working on my collection of bonsai trees, which includes a mix of Ficus, Juniper, and Chinese Elm. I've been researching nutrient ratios and understand that N-P-K values are crucial, but I'm unsure how to adjust these based on the specific needs of each species. My garden setup is well-drained, with a good mix of soil types, but I want to ensure that the fertilizer I choose provides the right amounts of nitrogen, phosphorus, and potassium for optimal growth. I've tried several general-purpose fertilizers in the past but haven't seen the desired results in leaf color or growth rate. Can anyone help me determine what nutrient balance I should aim for to enhance the health of my bonsai trees?
