Italian Alder - Alnus cordata

Discounts

The Italian Alder – Alnus cordata – is a fast-growing, hardy tree with a neat, conical shape and glossy, heart-shaped leaves. Originating from southern Italy and Corsica, it thrives in a wide range of conditions, including urban and coastal sites. Like other alders, it fixes nitrogen in the soil, improving fertility, and provides excellent shelter and food for wildlife. It is especially valued for establishing quickly in challenging locations.

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

Growing Instructions:

• Soil: Adapts to a wide range of soils, from poor and dry to heavy clay, but prefers moist, well-drained conditions. Tolerates chalk and coastal exposure.

• Sunlight: Prefers full sun but will tolerate light shade.

• Watering: Keep well-watered when young, especially in dry spells. Mature trees are tolerant of drought once established.

• Planting: Remove competing plants within a 2ft radius. Plant in a hole just larger than the plug and at the same depth as the surrounding soil. Firm in around the roots and water thoroughly. 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 browsing animals (e.g., voles, deer).

• Growth Rate: Very fast-growing; can reach 20–25m. Typically lives 50–70 years.
