Alnus rubra: Bareroot Red Alder Saplings

Red or Oregon Alder, Alnus rubra, makes a neat screening tree with a fairly narrow, tapering canopy and slightly pendulous branches. Unlike other Alders, it does not make a lot of suckers around the base. They have ruddy-brown catkins in spring, before the crinkled leaves appear.
Young plants are very vigorous, and will reach 20 metres.

The plants on this page are young saplings, ideal for planting as rough country hedging, or in woodland projects.
You can also buy larger Red Alder trees, which will give you more of an instant impact as a garden specimen.

Growing Red Alder

Red Alder will grow in very wet sites and poor soils, although it prefers sandier soils to heavy clay. It needs full sun.

Spacing a Red Alder hedge: Plant Red Alder hedging at 3 plants per metre, 33cms apart.
Alders in general are not well suited to formal, tidy hedges because of their vigour, but because Red Alder doesn't sucker much either, it won't form as dense of a wildlife friendly thicket as other varieties, so we think that Italian Alder or Common Alder are better for that purpose.

Note: Alders have invasive roots that can break old water pipes and damage the foundations of old buildings or walls. 15 metres away from vulnerable structures is a safe distance. New build, concrete foundations are not at risk.

Did You Know?

It hails from the West coast of North America, where it is a classic pioneer tree that quickly colonises bare ground after storms, fires, logging or shifts in a river's banks after a flood.
Alders fix nitrogen into the soil, making it available over time for nearby plants to use. They are commonly used to reclaim sites with very poorly fertile soil, or to help prevent erosion.
