Thats one of the few things I feel awckward assesing! I think you have a good one there but these grafts can be a bit iffy to say the least!

Marcus has elluded to it in the past, it would be kinda interesting to carry out a bit of thermography on some beech grafts.

 

 

 

I really like this one....

I believe there is an example in Lonsdales book showing a failure at these grafts due to incompatability, poor fusion in tissues.

 

There is a good one down the st here that has a poor root space and nver seems to grow, it goes a little dies back goes a little dies back, but certain thats the limited exploration capability of the roots as apposed to the graft, maybe a combination?

The strangest ones I have seen to date are where the rootstock has been so poor it has decayed away and the roots have been repleced by the scion. Make you wonder why they grafted it in the first place, also leaves a huge cavity at the base. Luckily it also seems to coincide with stunted canopy development.

Hello Marcus,

 

Imagine that that scenario is potentialy serious.

As you state, fortunate that the canopies are stunted.

 

Any shots of an example?

The fabled boabab Plane.

 

Came across this when I was driving down to Justins with a load of saws this morning.

 

It's on the A20 - Eltham road in S E London.

 

It reminded me of the tree Mick posted a while back.

So bottle butt is wide of the mark then........

Just looks burred to me? would hazard a guess that as a timber butt that would be worth a small fortune!
