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
