What is the best fertilizer for white pine trees?

Answer 1

A slow release organic fertilizer is the preferred fertilizer for white pine trees (Pinus strobus).

Specifically, white pines are trees that prefer acidic soils. The casting of their own needles builds up a natural mulch for the release of nutrients back into the soil and therefore into the roots. Otherwise, they favor applications of timed release organic fertilizers and of regular chelated iron treatments.
