Fertilize: For korean pine, use a balanced N-P-K fertilizer biannually in spring and fall. Follow label instructions to avoid over-fertilization. Feed more frequently in initial years; mature korean pine needs less. Apply when soil is moist, spreading evenly at the drip line, and always water afterward.
