Kretzschmaria deusta

Hi,

 

I've been asked to give my advice on a Lime tree with Kretzschmaria deusta in the Crown and I'd like to know if any of you could give me any advice as to what to expect over the next few years if we leave it as is.

 

There is no sign of any problems around the root collar but at about 3m where the crown starts the tree has lost one of 4 limbs. Where this limb broke out there is now an open cavity with Kretzschmaria deusta activity.

 

Good reaction from the tree.

 

I am little reluctant to put the Risi through it and am not sure how much an arborsonic will help me here.

 

Any tips, tricks or advice would be very welcome. :-)

 

Simon

When did the tree lose its limb?

 

Quanitifying the progression of dysfunction/decay is the key with Kretzschmaria, in our experience.

 

Using VTA, tapping with a sounding hammer and tomography are possibly not realiable enough to inform your management decisions.

 

Are you reluctant to use a Resistograph due to breaching barrier zones?

 

What's the context and targets like in terms of losing individual branches/whole canopy?

 

Any scope for reduction?
