Red Alder Tree (Alnus rubra) 

Originating in North America, Red Alder (Alnus rubra) is a particularly attractive tree, fast-growing tree and as with all alders ideal for planting in wet and damp ground.  Spring heralds the arrival of very large leaves, which are oval-shaped.  Like other alders, slender catkins cloak the branches.  Of interest is the inner layers of bark, which when exposed to air change to an elegant orange-red colour, and so hence the name of this tree.  Expect a final height of 25m (83ft).  Planted along with other alder varieties and Willow (many varieties of willow available) and other varieties of alder, Red Alder forms a worthy addition in the creation of an attractive wetland woodland, ideal for wildlife.  

Woodland Design Principles

Typically, this tree is planted in groups of between 10 and 25 trees.  This number of trees is ideal for creating a wildlife habitat and a meaningful source of food and shelter.  Spacing may vary between 1m (3ft 4in) and 5m (16ft 8in).  The aim is to mimic what nature intended and thus avoid artificial lines.  Blending of one species into another is suggested although bearing in mind different growth rates.  Alder and Willow would be fine as they are both fast-growing species.

Benefits of using our plug plant trees

Our trees are sold as plug plants, in other words the roots are encased in compost. This means that planting can be carried out at any time of the year, provided they are watered in periods of drought, compared to bare-root plants which can only be planted during the plants normal dormant period (November to March).  All of these trees are UK grown, which is important for successful establishment

Site Conditions And Evergreen Tree List
Our tree chart details which site conditions suit which trees and also which are evergreen or semi-evergreen.

Feeding Or Fertilizing Hedges
This is a task that can easily be over done. Any nitrogen based fertilizer will do such as 20:20:10 but the longer lasting ones which take 18/24 months are better as they are regulated by the weather and moisture therefore release slowly.

Woodburning Chart
If you are one of those lucky people that lead an eco lifestyle (VERY jealous if you are) and want to buy trees to burn, then maybe our wood burning chart (excel spread sheet) will help you decide. Ash, Eucalyptus Gunnii and Willow are worth looking at for their growth rates and calorific values.

Planting Tool
If you are looking to plant lots of plug plant or cell grown trees (the 10-40cm-ish) size range then maybe you should consider our tree planting tool. Tree planting rates of over 700 per day achievable.

Adding A Bit Of Colour And Attract Wildlife
Honeysuckle (Lonicera periclymenum) is very attractive, fragrant and attracts more wildlife to your garden. A bit on the vigorous side but worth the effort. A great addition to your project.

Tree Spacing
Broadleaf wood planting would be around 3m between each tree. Christmas tree planting for a commercial crop is around 1m.

Factors Detrimental To Cell Grown Trees
Too much/little water, animal Urine, excessive wind exposure (will slow growth), salt spray, frost on new growth, herbicide drift and over application of fertilizer.

UK Grown Volume Trees
All our volume trees are UK grown and as far as we know because we have never caught one booking a holiday overseas.
