Common Alder - Alnus glutinosa

Discounts

The Common Alder – Alnus glutinosa – is a hardy, fast-growing native tree often found along riversides and damp ground. It is recognisable by its rounded, serrated leaves and small cone-like catkins that persist through winter. Alder is valued for stabilising riverbanks, enriching soil with nitrogen, and providing excellent shelter and food for wildlife, especially insects and birds.

All our trees are grown using organic inputs and are peat free.

Growing Instructions:

• Soil: Prefers moist to wet soils and tolerates waterlogging well. Thrives in neutral to slightly acidic conditions but will grow in most soil types, including clay and loam.

• Sunlight: Grows best in full sun but will tolerate light shade.

• Watering: Keep well-watered when young, especially in dry weather. Mature trees are tolerant of periodic flooding.

• Planting: Remove competing plants within a 2ft radius. Plant in a hole just larger than the plug and at the same level as the surrounding soil. Firm gently around the roots and water well. Apply a 3-inch layer of weed-free mulch (ideally bark chip). Keep the base free of weeds for the first few seasons and protect from pests (e.g., voles, deer).

• Growth Rate: Fast-growing; can reach up to 20–25m in height. Average lifespan is 60–100 years, though some may live longer.
