the helical growth could be unilateral wind twisting and if that "twist" is forced in the other direction by some force then that can cause stem rupture sometimes (if the opposite twist is severe enough)

 

this bending and twisting (helical) can also be caused due to trees having a spiral grain especially where needed for distribution of water when root spheres are dry at one side to enable uniform distribution of supplies to all branches on all sides

Went and had a closer look at the stem wood today and im 99% sure that the dying of the cambium is caused by Bleeding Canker and as you've said the spiral grain would make it clear to me as why the cambium has died in such a spiral way.

Horse chestnut timber is very unstable and prone to splitting as it dries. I read an article I wish u could remember where, saying that horse chestnuts can be more likely to break apart or shed limbs when affected by b c, especially whilst still in full leaf.

yes b.c. seems to hit aesculus hard for some reason, wonder why?

 

i'll go and have a read:thumbup:

is there anymore helical cracks?

No, only spirals of cambium.

do you know what happening with the tree now or is it just being monitered

 

those twists could crack if twisted the other way, not a definate but a possibility

Haven't got a clue at the moment. Im sure i'll know in a few days as all i did was cover the home owners 'Duty of Care'.

don't mean to ask all the questions just interested thats all, really getting to grasp with trees from the aspect of body language and pests and diseases etc and would like to understand more

If no-one asked questions we could all still be using arbor paint.
