Grey Alder Sapling Trees

Grey Alder Sapling Trees - Delivered by Mail Order from the Nursery with a 1 Year Guarantee

Grey Alder, Alnus incana, is a very hardy tree that loves wet sites and will thrive on poor soil if it is in full sun. It can be used in a rough country hedge, but we really recommend Italian Alder or Common Alder instead for use as hedging. Grey Alder tends to produce suckering stems from the base of the tree that are good for supporting wildlife. Grey Alder trees can reach 30 metres tall in ideal conditions, but 20-22 metres is more normal. The plants on this page are young saplings, ideal for woodland planting projects. You can also buy larger Grey Alder trees and the ornamental variety, Alnus incana 'Aurea', either of which will give you more of an instant impact in a garden. You can also look at the rest of our hedging plants and bareroot shrubs

Grey Alder plants are only delivered bareroot, during winter (Nov-March).

Choosing a size:
When you are ordering Grey Alder, we generally recommend that you use plants that are graded at 40/60cms or 60/80cms, especially if you are using them for a hedge. They are cheaper than large plants, easier to handle and they will establish well in poor conditions. Use larger plants if you want a tall tree quickly.
All our sapling trees are measured by their height in centimetres above the ground (the roots aren't measured).

General description of Grey Alder plants:

Grey Alder is a very vigorous tree that will grow in any soil apart from chalk or very acidic peat. It needs plenty of sun and although it will grow on dry soil, it really prefers wet sites that are prone to waterlogging. It has silver-grey young leaves and shoots and the bark is also grey. It bears decorative, 10cm long, yellow-pink male catkins in early spring, alongside the green female cones, which mature by the autumn. The seed is windborne, but some small birds will still snack on a few of them. This tree is very hardy and will grow in the coldest Scottish frost pockets or exposed hillsides. The alders are pioneer species: they are quick to take advantage of open soil, quick to reach maturity and quick to die, by tree standards. After 90-100 years, Grey Alder's main trunk will begin to die back. If its lower stems are in the shade, the whole tree will die. This process is an essential part of woodland ecosystems and alders are often planted as companion trees for other, slower growing plants (like Oak) in forestry projects.
Note on Alder roots: Alder has invasive roots that can break old water pipes and damage the foundations of old buildings or walls. 30 metres away from vulnerable structures is a safe distance to plant Alder. New build, concrete foundations are not at risk.

History & uses of Alnus incana

Grey Alder is a European and Russian tree that was introduced to Britain in the 1700's. Grey alder wood isn't very strong or good to burn, but it is rot resistant and easy to carve. It is a traditional material for making clogs.
