Perfectly adapted to wetter or poor quality soils, the native Alder gets the 'glutinosa' in its latin name from the stickyness of its buds and young leaves. Featuring long catkins in spring and small, woody cones in autumn, Alder is also a wildlife magnet, supporting many native species of birds and insects throughout the year.Click here for more information.More Information

Alder Hedge Plant Description

Alnus glutinosa (Alder) has many attractive aspects. It boasts long narrow male catkins in spring, tiny female woody cones that release seed in autumn, but can stay on the plant longer and sometimes for more than one season (giving it some interest in mid-winter). Alder is wildlife-friendly, particularly for caterpillars, butterflies and moths, as well as 90 insect species and small birds. However, Alder'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.

Another great hedging plant for wet soils is Willow (Salix). It has a dense, leafy canopy and the autumn leaf fall builds up the humus content of poor soil. To see our full range of hedging that is good in wet soils, take a look at our Choosing The Right Species page.This page is also designed to help you choose the right hedge for your garden and has suggestions and alternatives for every wish list or requirement.

Alnus glutinosa is good at fixing atmospheric nitrogen not only ofr its use but it also makes nitrogen available to other plants growing nearby. You can plant Alder as a single species hedge, or combine with other native species and allow them to receive the atmospheric benefits which Alnus glutinosa provides. It is good in all soils other than very alkaline, and in sun or semi-shade and particularly good in coastal positions. Due to its fast growth rate when young, it can be used to form an effective windbreak to protect other plants. Although deciduous, Alder keeps its leaves quite late, often into November.

If you still need help to decide which hedge is right for you, we'd recommend that you visit our Choosing the Right Species page which has suggestions and alternatives for every wish list or requirement.

Further Information
Further Information

You’ll 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 you’re 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.

Pruning Advice
Pruning Advice

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.
