Growing Alnus glutinosa Successfully in NZ

Alnus glutinosa thrives in full sun with well-drained soils typical in many New Zealand gardens. Its drought tolerance makes it an excellent choice for low-maintenance landscaping. Ensure good air circulation and avoid waterlogging to keep plants healthy and vibrant all year round.

Alnus glutinosa Care Tips

To care for Alnus glutinosa, provide regular watering during dry spells but avoid overwatering. Prune lightly after flowering to maintain shape and encourage bushier growth. Mulching helps retain moisture and control weeds, supporting healthy plant development.
