2nd, 3rd & 4th September for the UK 'training for the trainers' workshop Check the calendar on the VETree website for updates/changes etc...... .

Guess that depends on whether the authors intend to update their own work or whether they have access to experience/evidence of examples of things like I dryadeus at height which challenges the existing texts. Perhaps there are new works in the wings ? .
-
Seen it fruiting high on trunks up to 5/6 meters Experience shows us that text books are part of the ongoing knowledge of a subject, not the definitive answer. .
-
One to be extremely careful of I would say. It 'looks' like a Morel but it could be the false morel - Gyromitra esculenta pretty poinsonous .

If your interested in the work that the scientists at Kew are involved in then perhaps give a couple of minutes of your time to look at this...... BBC News - Kew Gardens jobs to be axed in £5m shortfall https://www.change.org/en-GB/petitions/globally-important-conservation-and-science-under-threat-at-royal-botanic-gardens-kew-due-to-uk-government-cuts-5m-deficit-will-lead-to-loss-of-over-120-posts?recruiter=88977540&utm_campaign=mailto_link&utm_medium=email&utm_source=share_petition .

Sold it last night to a Russian Oligarch in Highgate for 250K .

Think its Chondrostereum purpureum - silver leaf fungi The purple jelly disc - Ascocoryne sarcoides, is not really flat like the ones in Kevin's poplar picture. They are more like jelly babies. .
-
makes you wonder if sections like this gave sculptors like Henry Moore & Barbara Hepworth inspiration .
-
The core is full of the brown rot of Laetiporus sulphureus, the failure showed how durable the outer skin of the monolith is as this peeled section shows .
-
During the winter winds we lost an old oak monolith when a younger oak uprooted and fell across it. a fairly hefty whack, but looking at what was left of the root crown it shows how little footplate is needed to keep these things upright for decades. .

Auxins are responsible for cell stretching which increases the capacity of the cells to transport nutrients from tip to root, and can be found in leaves, buds & branches. Cytokinins are primarily responsible for the division of cells in the root and shoot tips and in the formation of branches If you prune branches (removing the branch tips) the cytokinins move down to and concentrate predominantly on root development instead of both root and branch development. Eventually if the tree is healthy it will look to grow/put on new shoot/branch tissue (meristematic tissue) which will be full of cytokinins hormones. that doesn't really answer your question though, does it read ok and make sense ? It's pretty much what I can recall from assignments. What course are you doing? .

What's the battery backpack like on your one Mark? Did you not think about the neck brace accessory then. .

Hello Owen Thanks for updating Have you got access to the tomograph to show us? Had John in to carry out some tomography for us 7/8 years ago How is he? . -

Managing Trees with Decay & Dysfunction
David Humphries replied to David Humphries's topic in Tree health care
Never seen Laetiporus fruit on this particular tree so hadn't considered it as a significant hazard to the adjacent property. Having now seen the extent of decay in the failed section, the remaining canopy will be reduced to lessen the sail. .

Managing Trees with Decay & Dysfunction
David Humphries replied to David Humphries's topic in Tree health care
Old oak on our boundary overhanging a neighbouring garden. It lost a significant portion of its canopy (in part due to the brown rot of Laetiporus) during last years st judes storm Only just got around to dismantling the hung up section today. We rigged it down between an impact block up on the tree and the Landy winch. .

Ta muchly .

Does anyone know what percentage of the strength is in the core of Blue tongue? .
-
Think it's not far off 6 years now .
-
Would be interesting to see (over time) how/if wood changed on a tree that had lost its neighbour due to being loaded (or not) by additional wind force, eh Jules .
-
a tad Oompaloomperish, no? .
-
This springs flowering and bud swell at the internodal prunning points appear to show the old girl doing well .
-
the reddish clolour is possibly Anthocyanin pigmentation in the sap I think Anthocyanin provides defence against environmental stresses like UV and cold .

Hello Jennifer Do you mean landscape planting in general or newly planted trees within the landscape? Not really sure about improving existing systems, but have you considered slow release irrigation systems like Treegator? Treegator® - The Original Watering Bag for Trees | Home Oddly enough I was only looking at a couple of these earlier this morning down in the heart of the City of London .
