Specifying Trees

All trees are specified as girth size with their ‘girth’ being measured in centimeters one meter above ground level (i.e. 12-14cm girth).

Semi-mature trees start at 20cm girth and progress in increments of 5cm, e.g. 20-25cm, 25-30cm, etc.

Conifers and multi-stemmed trees are generally measured by height in increments of 50cm, e.g. 350-400cm and supplied as a feathered or bush form.

When conifers are specified by girth size, this indicates a clear stem is required.

Root Specification

Bare-root (BR), Root-balled (RB) or Container Grown (CG)

At inquiry stage we recommend how your chosen  trees should be specified – Bare-root (BR), Root-balled (RB) or Container Grown (CG).

 

Bare-root trees – November to end of March

Bare-root plants are lifted from the ground, either by hand or, more usually, by mechanical means. Trees will be undercut and lifted, keeping as much of the root system intact as possible. However, even with a regularly transplanted tree with a relatively compact root system, approximately 25% of the root will be lost on lifting. Soil clinging to the root system will be shaken off; hence the term ‘bare-root’ and the tree should immediately be bagged. Co-extruded polythene should be used: these are bags which are extra thick, black inside and white outside to reflect heat.

At Nangle & Niesen all bare-root trees are placed in co-extruded bags at the time of lifting in the field. If this was not done the delicate fibrous roots would dry out very quickly and the tree would either die or struggle to survive on site because its root system has been severely damaged. Always specify co-extruded bags for bare-rooted trees and check that your trees are being handled correctly.

 

Root-balled trees – November to April

Here the tree is lifted from the ground with the soil intact around the root system. On removal from the ground the root-ball is wrapped in biodegradable hessian and non-galvanized wire. The root-ball should be planted intact with the hessian and wire left on. Once planted the non-galvanized wire soon breaks down and the hessian will rot, allowing the root system to develop. The whole benefit of ‘root-balling’ is that the root system remaining after lifting (you will lose about 35% of the root on a regularly transplanted tree) will not be disturbed during handling, transportation and planting.

Container grown trees – Available all-year-round

Container grown trees have a ‘complete’ root system and should therefore establish well once planted. Trees are lifted either bare-rooted or root-balled and placed in a container (between November and March) and then grown on for at least one growing season, i.e. a tree ‘potted up’ in January would be fully rooted and ready for planting by September.
