Anyone know what causes it?

 

Helical growth of wood fibres are formed by a torsional twisting force. (wind load for example)

 

Ok if the force stays the same but can unravel like a braided rope if the force becomes opposing which can occur if neighbouring trees are removed and the twisted tree becomes wind loaded from a different direction it's not used to.

Cracking leaf size on this tree in a customers garden today. Don't think I've ever seen/noticed one before and didn't know what it was until told.

Indian bean tree which may be regularly pollarded so the leafs oversized?

Paulownia int it?

Cheers David, I've heard different reasons over the years, such as spin of the earth and even continuous following sun through the day.

 

Nice to hear your reasons David. 👍

what would cause one twist to be dead?

Its hard to see in my crap pics, but theres a dead half twist, with a live tissue twist too, like its intertwined, but it's not, its still the same singular stem, twisted, with half the stem dead (from base to tip)

One and the same, just wear different outfits at different times of the year.

 

I'd be willing to wager that no one has seen Herr Mattheck in the same room as Santa Claus ?

The twisted section that's dead may simply just have it's specific root connection gone/dysfunctional.

 

Which may be associated with the torsional force at the base of the tree putting too much compressive force on that root or it could be an abiotic/mechanical reason for the root failure .

 

Either way I'd imagine that there's a dead root at the base of the section that's dead.

 

 

 

Ps, do you mind, I'm trying to watch the Chelsea game
