Hi Wayne, the tree that prompted my query also has minor dieback from tips,
prompting my first suspicion of damage from adjacent development - I was
merely speculating that delayed bud burst was a further symptom of the same
problem. Development of close adjacent land was completed last year.

So I guess I can refer to the symptom as being 'possibly' associated with
root damage...or possibly a quite normal result of other complex factors!!
Or I can avoid all speculation about it in the report (safer perhaps).

I am so delighted to see true intellectual discipline in action! Real
*thinking*, real *questioning* rather than presuming. Advancing an
hypothesis. Advancing of alternative hypotheses.

I look forward to more, and their testing with disciplined analysis and
observation/experimentation. And I am particularly delighted to hear that
most intelligent of statements--"I don't know." (See
https://newrepublic.com/article/100368/i-dont-know )

Wouldn't it be wonderful if all listserv participants everwhere subscribed
to this concept? No more defending of opinions, traditions, sacred cows,
etc.?

Now, I don't *know*, but I suspect that delayed bud-break just might (in
some cases) be a reflection of a compromised vascular system, and that
continued periodic, but regular observations and comparisons with other
trees of similar size and age (and even other sizes and ages) might be
revealing. While dieback should be cause for similar study, a general lack
of overall leaf quantity, quality, and number also may signal trouble. It
other cases I suspect that trees simply outgrow places to collect nutrients
and conduct respiration.

I hope others will dig deeper (perhaps literally?) into this issue as well
as other symptomology that has predictive value with respect to tree
condition, which would advance both science and practice.

Don't know. Go here https://www.metoffice.gov.uk/
climate/uk/about/state-of-climate and click on the 'Phenology
supplement'
link and you will see regional correlation data for bud burst,
temperature,
rainfall atc. for various species. Not conclusive, so much so that it
suggests that the inter-relationships are so complex and the lags so
inevitable that they'd be hard to pin down for normal trees. Just looking
at the graphs I can see that rain means cloud means less sun and lower
temperatures, so it might be that the rain is interfering with normal
temperature or daylighting triggers.

Good luck with it. I have a vague recollection of reading once that
traumatised trees take a couple of extra days to get vascular pressures
up
to normal and deal with partial cavitation in spring, but I might just as
well have dreamt it after too much cheese.

Well, in the absence of takers for my query, i have learned that trials
with Spruce showed bud burst being brought forward by nutrient
applications. Might this mean that nutrient deprivation (or water
shortage
for that matter) - perhaps as a result of root damage - could delay bud
burst? It makes sense to me that the tree might prioritise allocation
of
resources to root regeneration after damage, prior to flushing, but it
would be nice to see it writ as fact somewhere.

Dear all, I realise there is some variety in timing of bud burst
between
individuals, but I suspect a late leafer (in comparison with all
around it)
is at least partly due to root damage during development. I can't
find
reference to the symptom/cause in my books though. Am I making it up?

Any thoughts appreciated.
