Lawson cypress from seed
JSN replied to Paul in the woods's topic in Forestry and Woodland management
The seeds need a period of cold temperature before it’ll germinate - vernalisation. You could sow now and let nature take care of this, or follow the instructions here: Chamaecyparis lawsoniana - Forest Research WWW.FORESTRESEARCH.GOV.UK -
Hi John - if you haven’t got them already, the AA technical guides are a good resource which include pre climbing tree checks. Arboricultural Association - Book Shop TREES.ORG.UK A source of publications, guidance notes... Otherwise this is, (was?), the bible for hazard trees.

I quite like a plucky amateur but you appear to lack a fundamental understanding of tree biology and bio-mechanics. To bring you up to speed, can I suggest that you read, Trees: Their natural history - Thomas, and Stupsi introduces the tree - Mattheck. Also, If you have the academic chops for it, The body language of trees - Mattheck & Breoler, and Applied tree biology - Hirons & Thomas. “The notion that Ivy kills the tree it grows on can be traced back to Theophrastus in the fourth century BC, without anyone stopping to think whether it can be true!” O. Rackham. Maybe try his book, Trees and woodlands of the British landscape, time your on.

Wtaf - this is some scene of patronising condescending weapons grade bull shit. 10 pages ago you didn’t know about juvenile and mature leaves and now this nonsense. I also find it highly duplicitous that you require references / qualifications / experience for everyone else’s comments but provide non yourself. Wow indeed.
-
As I understand it Ash are susceptible due to their open branching structure allowing more light to reach the inner crown / trunk. They are also late into leaf and often early to drop, in comparison with other trees, which favours Ivy’s main growth periods of early spring and early autumn.
-
The notion that Ivy kills trees is a common logical fallacy that mistakes correlation with causation. The conventional thinking is that only stressed trees - and Ash - succumb. Is the high incidence of Ivy covered trees you have noticed due to Ivy being an invasive tree killer, or is it due to an increase in the incidence of stressed / declining trees in the landscape? http://www.arborecology.com/articles/pdfs/ivy_friend_or_foe.pdf

Not for much longer - Metaldehyde is banned from March 2022.

I would condemn this tree from the pics. The hard landscaping probably damaged the roots way back when. Although you have just noticed the defects - I imagine it’s been in decline for a growing season or three. Pics of the other side of stem and whole crown would be helpful.

Just putting this out there….. If it were mine, or if I was advising a client, I think I’d be inclined to take the hedge out altogether and replant with a different species. You could try and eradicate the caterpillars, but they’re obviously in your area - so they will come back, you won’t get them all - so your hedge will always be declining and scabby, and it will be a constant battle to maintain a poor hedge. Plus applying noxious chemicals into the wider environment isn’t good. Alternatively, you could plant a new hedge this autumn and spend the next few years watching it come into fruition and maturity. The first option is negative, time consuming and involves nasty chemicals. The second, whilst initially drastic, is positive and ultimately rewarding.

The types of qualifications to look out for are ND, level 4, HND, level 6, BSc, MSc, or, Lantra PTI, in arboriculture. Could also check for professional membership of Arboriculture Association or Chartered Institute of Foresters. More important to check that chosen expert has professional indemnity insurance to cover giving the advice you require. Both AA and ICF list members by area.

Could it be excess nitrogen? leaves look very nitrogeny - (if that’s a phrase). Possibly from fertiliser runoff / muck heap / sewage treatment works?

This is a good match from Collins.

Can you claim off your insurance for the cost of clearing the tree and reinstating the fence? Unfortunately the timber has little value in offsetting this cost.

Is it a graft line? Is the top bit fancy? - cut leaved or purple. Above the line looks thicker in girth.

JFL gets a bit of a kicking there. Not sure I’d be comfortable signing any tree off as ‘safe and healthy’, doubly so one in the central reservation - with crown symptoms - from 50 mph! Also thought , ‘to be put on enquiry’, was a lovely turn of phrase. Good stuff.
