Get ya Galls out for the boys

[David Humphries]

The ones i've seen are all over the leaf, are smaller than the ones pictured and more often than not red in colour

 

 

 

Beyond my Ken, better call for the Bugman.

AHHHHHHHHH

 

Aye! Ken!

[Amelanchier]

None of my cartoon dusty oversized books have any nail galls occuring on Ash...

Nothing of great significance

Doesn't it depend on the tree and where it is situated?

 

If all the leaves were infested with the galls, this would reduce photosynthetic space, possibly leading to early leaf drop then to a stressed tree more susceptable to attack by fungi?

 

Rhytisma acerinum ? Guidnardia aesculi? reduction of photosynthetic space in both cases as well as early leaf drop leading to a stressed tree? There are many others - leaf miners etc nearly always referred to as 'nothing of great significance'. Both Tar Spot of Maple and Chestnut Leaf Blotch infestations can be reduced by removing the fallen leaves from the site.

Interesting..... the Ash I have seen this on do suffer from and always have suffered from early leaf drop, and are in a hedgerow very close together..... and very often the leaves have black spots on them (tar leaf spot?!) but I did not think that Ash were susceptible to tar leaf spot????

Possibly to a degree Tim.

 

Although I suspect, after watching 5 years of Cameraria seemingly not having an annual effect on the photosynthetic/energy balance on HC, that the Trees appear to be biomechanically productive.

 

Glynn Percival from Barchams/Reading Uni, would lean and advise toward the other side of the coin, as he is currently carrying out limited studies on the productive qaulities of Conkers affected by Cam. Showing a dramatic loss/drop in seed weight mass and germination success.

 

So maybe a future Treescape sans HC.

 

But as for the Cut Leafed lime shown earlier, this tree has had the galls pretty much every year for the last decade at least, and still thrives.

And the galls proliferate across the entire canopy.

 

I've not read any specific reference, but I would imagine Trees have a dynamic % of productive leaf surface that can be loss tolerated, by indigenous affliction.

Twas quite funny yesterday, client rang me up in a bit of a state, "My lime tree is smothered in red spider mites, what can you do?" it was lime nail gall s, at least it put their minds at rest when I explained that it isnt too detimental to the trees health.

Bad case of Oak Gall on Quercus palustris 'round here...........and shouldn't we be getting our galls out for the girls?
