Japanese Pepper (Zanthoxylum piperitum) prefers a bright position, ideally by a south-facing window. Keep the potting medium slightly moist, allowing it to dry out moderately between watering. Apply fertilizer during the summer months.
The crown can be shaped by pruning in spring and summer; this will make the crown more bushy and full. The sap of the plant has a lovely minty fragrance. Try rubbing a couple of leaves between your fingers, and enjoy the fresh fragrance.
Tolerate temperatures between 12 and 30°C.
Japanese Pepper is an excellent candidate for bonsai cultivation.
