T R A D E P A G E S General Public Click HereWholesale NurseryThe largest Tree Growing Nursery in the UKFacts and Figures Production Area Over 550acres (220ha) Trees in Production Over 750,000 Number of Tree Varieties Over 150 Field Stock Locations Hampshire/West Container Stock Location Romsey, Hampshire (click here for map) Specifying Trees All trees are specified as girth size with their ‘girth’ being measured in centimetres one metre above ground level 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 When conifers are specified by girth size, this indicates a clear stem is required. The following pictures indicate the size of tree to expect for your specification.

* sizes shown in above set of pictures § Check availability Not all species are commercially available in all sizes. We have shown by ticking the relevant boxes our usual availability of stock and in broad terms this is a sensible guide to what is generally available on the commercial market. § Root specification Bare-root (BR), Root-balled (RB) or Container Grown (CG) Throughout the tree section we recommend how trees should be specified and this is reflected in the availability guide that is – 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 Hillier Nurseries 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. The benefits are:- § Value for money § Light to handle § Quick to establish with correct after-care Points to remember:- § Only trees under 18-20cm girth should be specified bare-root, and not Fagus, Betula, Quercus, Liriodendron, Liquidambar, Ginkgo, Parrotia and all conifers, these must be RB or CG. § Trees must be sealed in double thickness, co-extruded polythene bags after lifting · Root-balled trees – November to AprilHere 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-galvanised wire. The root-ball should be planted intact with the hessian and wire left on. Once planted the non-galvanised 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. The benefits are:- § Root system once lifted will not be disturbed § Packaging bio-degrades § Root-balled trees are protected from the rigours of commercial planting Points to remember:-§ All field grown trees 18-20cm and over must be root-balled § Certain species that are field grown must be root-balled e.g. Fagus, Betula, Quercus, Liriodendron, Liquidambar, Cercidiphyllum, Eucalyptus, Ginkgo, Parrotia and all conifers § Root-balled trees should be planted with hessian and wire left on to maintain the integrity of the root system · 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. The benefits are:- § No root loss during lifting § Planting can take place 12 months of the year § Hillier-handles make handling on site easier Points to remember:- § Quercus ilex should always be specified as container grown § Trees will be accustomed to irrigation on demand and after-care is crucial § Hillier trees are peat-free Table showing Approximate Weights and Measurements of Root-balls and Containers
