Trees – Overall Height

Most trees are graded to heights appropriate for their age and development.  Beneath the images, the following table indicates the typical grades for each tree size or open in Excel here:

For larger feathered trees (6-8 cm +) the girth grade becomes more significant in specification than the overall height.

The designation of Whip or Feathered form, depends on the characteristics of the species and the method of culture.

Although multi stemmed and bushy trees are specified primarily by OVERALL HEIGHT (qualifying also the ROOT PROTECTION and the SIZE OF CONTAINER, if appropriate) they may also be specified by reference to the number of stems and/or main branches arising from or near ground level and also a measure of the diameter of the head.  For example, Betula pendula is typically specified with 2 stems or with 3 stems.  An indication of the girth of the thinnest or average stem may also be indicated.
