Do you guys have recommendations for the go to fertilizer ratios that nurseries use? I'm talking about seedlings from 2 months to let's say 18 months for example, mangoes or similar...
For some reason, most seedlings I purchase come with very wild and very strong roots. I have seen bags of 13-40-13 at some nurseries before, but I'm not sure if all that P is good.
What is your experience please?
