Bronzing of foliage on Yew

[bikerdave16]

I would appreciate any observations you have on the Yew shown in the photos.

 

I suspect Phytophthora, I checked for staining in the bark cambium but appears inconclusive

 

This year’s extension growth has reasonable vigour and bronzing occurs on older, wood, growth.

 

Lower foliage around the bole is lush/good, top half is affected.

 

the surface around the tree is not unduly wet, not checked the water table.

 

There is a fowl water pipe within a few metres of the trunk but I do not think this is significant.

 

Any thoughts welcome

 

Cheers

I witnessed an ancient Yew go brown (like your subject) and then recover after being mulched, watered and fertilised.

 

I would think the soil around the yew needs improving.

I don't like the sound of the foul water pipe - it would be worth investigating further

Thanks Paul, I think I will.

Thanks David, sound advice, like the pic's of the Yew, great recovery.
