We grow our trees to conform to British standard BS 3936 – Nursery stock specification for trees and shrubs. This outlines a specification on form and size for the trees we supply.
The following table shows the tree specification with it’s corresponding girth size.

| Light Standard (LS) | 6-8cm |
| Standard (S) | 8-10cm |
| Select Standard (SS) | 10-12cm |
| Heavy Standard (HS) | 12-14cm |
| Extra Heavy Standard (EHS) | 14-16cm |
| Advanced Heavy Standard (AHS) | 16-18cm |
| Semi mature | 18-20cm + |
The heights deciduous trees attain with age varies greatly between species and varieties which is why we prefer trees specified by girth but if you have a particular height in mind we will do our best to oblige. The following table gives typical tree heights by girth size.
