    Is this SBD?

    In brief, the overall risk from SBD is mind-boggling low. What that means is there’s no need to fret about putting up signs, or fencing, or pruning, unless you have a tree that’s a repeat offender.

    Most of the research into ‘Tree Architecture’ (Arboritecture) is from France and Canada.  That means it’s published in French, which many of us can’t read. This piece by Tom Joye, in the UK’s Arboricultural Association’s Arb Magazine, is a great introduction to the world of Tree Architecture, and what it can reveal about the ‘development stage’ of a tree.  It’ll have you look at growth and epicormic growth in a different way.
