Tree Sizes

Trees are grown in the ground then dug with a specially designed machine in winter, the whole root ball of the tree is thus preserved. The root ball is then potted into either a rigid plastic container or grow bag until it is fully consolidated.

Our policy is to sell only stock that has a fully developed root system. Trees from 25mm calliper up are treated this way.

Present height is not such a good judge as to the eventual height and shape of the tree as is the calliper, or thickness of the trunk, which is measured 300mm above ground level.

Generally speaking:

LITRE
CALLIPER
HEIGHT
SPREAD
45
15 - 25mm
1.5-2m
.6-1m
75
25 - 35mm
2-2.5m
1m
100
40 - 50mm
2.5-3.5m
1-2 m
200
60 - 80mm
3.5-4.5m
1.5-3m
300
80 - 90mm
4.5m
3-4m
400
90 - 120mm
4.5-6m
3-4m
600
110 - 140mm
5.5-7m
4-5m

These measurements are a rough guide only and are dependant on the variety of the tree.

Pot sizes & planting advice

The general rule of thumb for planting is at least twice the width of the rootball and to the same depth. Here are the dimensions of the pots, therefore just multiply the diameter by two to obtain the planting hole width.

Pot size

300mm
250mm
45L

We also recommend that a light root prune be given to the rootball prior to planting to encourage new growth.
