The soil should have beneficial mucronation, which can lead to radical decay. To ensure sufficient improvement, Japanese pine necessitates recurring fertilization. A proportionate gradual-exhaust fertilizer with an NPK proportion of 10-10-10 or 14-14-14 is endorsed. The fertilizer should be employed in early vernal, just before new augmentation commences, and once more in early autumnal. The quantify of fertilizer to be employed depends on the age and enormity of the organism. For juvenile Japanese pines, employ 1/4 to 1/2 cup of fertilizer per organism. Developed arbors may require 1 to 2 cups of fertilizer. It is crucial to evenly channel the fertilizer environing the drip borderline of the arbor, avoiding pilot junction with the caudex. Subsequently exertion, humidify the soil thoroughly to aid the nutrients infiltrate the radical zone.

Plant the pieces in their own pots or right in the ground, giving enough water and sunlight. To multiply through cuttings from stems, take 4-6 inch long stem cuttings from healthy plants. Take off the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a potting mix that drains well and keep them in a warm, humid place. Cuttings from leaves can also be used to multiply. Take healthy leaves and put them halfway into a potting mix that drains well. Keep the soil damp and give indirect light.
