Alnus glutinosa Hedge Plant Description
Alder hedging is a fast-growing deciduous hedge plant that boasts long catkins in the springtime and small, woody cones throughout the autumn. Alder has a dense, leafy screen that means it makes a wonderful habitat for wildlife such as butterflies and birds, as well as caterpillars, moths and more than 90 other insect and small bird species.
As well as being wildlife-friendly, Alder hedging is a fantastically adaptable plant that can thrive in wet and poor-quality soils - it can even tolerate prolonged periods standing in water of up to 30cm deep. This means it is a good choice for coastal positions and other waterside locations, such as around lakes and rivers. If your garden has a tendency to become waterlogged, Alder is a perfect choice of hedge.
Alder prefers sun or semi-shaded conditions for optimum growth and makes an effective screen to shield other plants from harsh weather conditions. Due to its dense foliage, Alder makes a highly effective windbreak.
Alder hedging can be planted as a single-species hedge or can be combined with other native species. Alder converts nitrogen from the air into soil-based nitrates, that can fertilise both the Alder hedging itself and the plants around it, which is why it thrives even in poor soils.

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.
