Leaf disorders

[David Humphries]

..........I assume you never got to the bottom of the H.C problem? I thought at the time that due to the localisation the cause was climatic - but again it's only a guess.

 

 

Didn't get any further.

 

A few tatty leaves in north London don't amount to a hill of beans when it comes to priority at Forest Research, they are somewhat otherwise engaged surfing the tidal wave of iggly wigglies coming at them.

At least they reply to you! I sent in a Chalara report, as I think did a local authority and as far as I know neither of us got an answer. That was, IIRC, two years ago.

 

Shouldn't complain because their backs are against the wall with the influx of p&d's and they're doing the best they can.

[David Humphries]

Were the reports sent in by using the tree alert app Gary ?

[Gary Prentice]

Mine went by email with photo's. I don't think the app had been released at the time. I may be wrong.

[David Humphries]

Ok, just interested as I was talking with them a few weeks ago regarding the reporting interface.

 

I believe the app isn't supported anymore (since 2013) due to funding issues, they now want people to use the online form.

 

Bit of a shame really, cause I would of thought the easier it is to report tree disease the more likely people would be to interact with it.

Spotted this on a holly the other day

[David Humphries]

Variegation looks like.

[Gary Prentice]

Not that unusual in holly IME.

 

This is where my lack knowledge fails me! My assumption is that a branch produces energy to grow, with the surplus being deposited towards the root system. Therefore, in the absence of chlorophyll ( or other photosynthetic 'elements') how do these shoots continue to grow?

 

I understand that variegated trees have slower growth rates ( less energy production = less growth) but how does a 'sport' branch with no chlorophyll at all grow, unless it it deriving energy from the tree as a whole?

 

 

Sorry for the derail David.

Midi-chlorians obviously

 

intelligent microscopic life forms that lived symbiotically inside the cells of all living things. When present in sufficient numbers, they could allow their host to detect the pervasive energy field known as the Force.

So you don't know?/ can't answer the question?
