Growing
Primula japonica prefers a shady to partially shaded location with moist, humus-rich, neutral to slightly acidic soil. The plant requires consistently moist to wet conditions and does not tolerate dryness. Regular watering is important, especially during dry periods. Propagation is done by division in early spring or by sowing. Old flower stalks should be removed to direct energy towards growth.
