Genetically Driven Bad Crotches

Recommended Posts

Went to Duncan Slater's Fork workshop in Edinburgh a couple of days ago. His research shows that 93% of unions with included bark are associated with strain being removed from the branch by mechanical bracing further up the branch, such as by crossing or rubbing branches, at some point in time.

So trees with a naturally dense and tangled crown, such as whitebeams or hornbeams for example, or fastigiate cultivars of many sp. have a genetic predisposition to 'bad crotches'.

This bloke's notion that trees communicate with each other in myriad ways, particularly below ground, may seem far fetched?

But the underlying science supporting tree intelligence is indeed fascinating IMO.


Even though it may mean I roast in hell for eternity for my vile sap soaked transgressions!

I had heard there was a bad batch of London Plane - platanus X hispanica which originated from a nursery that grew its stock from cutting so all the trees were genetic clones.

Not sure if this is true or not




This is true. I believe Russel Horsey (ex Bristol TO) was investigating this and removing a lot of 30 ish year old planes for that reason. They were just randomly dropping large sections. All around public spaces.
