Alnus glutinosa Hedge Plant Description
There are numerous attractive benefits to planting Alnus glutinosa in your garden or landscape area. Firstly, Alder boasts long narrow male catkins in spring and tiny female woody cones that release seeds in autumn. The seeds can stay on the plant longer and sometimes for more than one season, giving Alder some interest in mid-winter. If you're looking for a wildlife-friendly hedge, we recommend considering Alder. Alnus glutinosa attracts caterpillars, butterflies and moths, as well as 90 other insect species and small birds.
While being wildlife-friendly is a fantastic benefit, Alder hedging's greatest asset is its use near water and on impoverished soil. It grows best in moist or even wet soil and will tolerate prolonged periods of standing in water up to 30cm deep. If you're looking for an excellent hedging plant for wet soils, we recommend Willow (Salix), as this species has a dense, leafy canopy and the autumn leaf fall builds up the humus content of poor soil. You can view our full range of hedging that thrives in wet soils, by visiting our Choosing The Right Species page. On this page, it will guide you into choosing the right hedge for your garden and has suggestions and alternative for every wish list or requirement.
Alnus glutinosa is excellent at repairing atmospheric nitrogen not only for its own use but also to make nitrogen available to other plants growing nearby. Alder can be planted as a single species hedge, or combined with other native species, allowing them to receive the atmospheric benefits that this plant provides. Alnus glutinosa develops well in all soils except extremely alkaline soil. It prefers sun or semi-shade and is particularly good in coastal positions. Due to its fast growth rate when young, Alder can be used to form an effective windbreak to protect other plants. Although deciduous, Alder maintains its leaves quite late, often into November.

Youll see our recommended planting densities for each size and root type listed in the product grid. We suggest that you use these as a guide, taking into consideration how long youre willing to wait to see your finished hedge. As a rough indication bare roots can be planted at anything from 3 to 7 per metre and cell grown between 4 and 6 - the higher densities here would need to be planted in a double staggered row or zig-zag.
For more information on planting distances please see our planting density advice section.
General hedge trimming of Alder should be done in late autumn. It is important to prune Alder at the right time, so as not to remove new growing shoots. Unusually, although deciduous, Alder is actually starting to develop new growth through the latter part of the winter months (even though you can't visibly see it) when other deciduous plants are still dormant and so unlike other deciduous species for which pruning is ideal at this time, Alder needs trimming a little earlier in the year.
Pruning in late autumn when the plant has stopped growing will also prevent sap bleeding which can happen if the plant is still in a growth phase. This has a tendency to attract bugs which may bring disease so should be avoided to ensure you keep plants healthy.
