Ash Tree Die Back .

[Henarar]

they cleared about 5 acres of wood down the road from here last year, half of it was ash and it was infected
the chap that manages it said there are different strains of ash and they are hoping some will be resistant.
he also said that infected trees can become prone to falling as it affects the roots

Only young saplings are actually dead round here. I would say that 2/3 to 3/4 of the population are showing various levels of infection. There are 3 mature ashes growing beside the folds. The 2 outside ones are badly affected and the centre one is showing no signs at all, no matter how carefully I look.

Would I be right to worry if trees take a while to come into full leaf?

The majority of Ash here are stems from steeped hedges. The roots are much older. I have noticed some have a tendency to be late, but they have been even later the last three years.

All the slow ones are on the tops of hills, and are in with a jumble of species (sycamore, hazel, thorns, Devon elm, willow, the odd crab apple). Wondering if the long spells of dry weather has affected them, or whether it's the lurgy.

save some seed from that centre one then...

We lost a big ash tree in the storms earlier this year. The whole trunk was completely hollow inside. 2 more died this winter (no leaves but still standing yet) and a lot of the others aren't looking healthy at all. Lots of dead leaves next to the green ones. Even the healthy looking trees are slow at coming into leaf

Around me in Hampshire nearly every Ash seems to be affected to some extent. It may not be immediately obvious if you are not sure what you are looking for. The canopy will not look as full as it should, a proportion of small branches will be dead with no leaf and some trees may have an excess of seed which often occurs in trees suffering stress. The tree in my photo is suffering but it may not show at a glance.

The disease makes the timber brittle so once trees are badly affected it is not safe to climb them to take them down. Not a problem if they can just be dropped but an expensive one if they are close to buildings or roads.

Its a bit depressing, all the Elms are gone, even my resistant one is on its way out, my Walnut tree is on its way out with some fungal infection. The public get very excited about tree planting but I don't think enough attention is given to tree diseases, why have we so many around killing large healthy trees?

Not sure if this is Ivy or Die Back

Looks like both?

Losing a lot of big trees around here now as drove down a local main road a couple days back for the first time in several weeks and it winds along by the river and is simply beautiful but to my horror there are no semi mature ash trees left as vast areas are now totally without leaf.

In hedges the die back seams to start with the wood browning from the outer tips and a blue looking mildew below that And only affecting parts of a clump to start with but Large trees the dieback is far more rapid as the outer edges of the branches begin to lose leafs and it’s not long before they are bare. Really think this weather isn’t helping as trees are already very stressed

Typical the trees appear rather dark to look at because the light grey bark is dead.

why have we so many fungal diseases killing trees? It is simple, look at the garden centre and forest nursery trade, it is Virtually all imported Stock. Even where the nursery is growing it themselves most are using imported plugs.
ash die back was bought in by a woodland trust, who were using imported Whips for planting although there were 3 small nurseries growing stock with in 5 miles of them.
when Inwas in the trade, I was supplying stock to a large british nursery who advertised all there plants were grown by themselves!

Good reason Australia border force are so hard about keeping just about anything out.

Down to global trade and the halfwits at the forestry commission and DEFRA allowing it in.

We were all told to plant trees of native providence in our planting projects then they found out that die back jumped from eastern Europe where it was making slow progress west.

Why should we be surprised when British seeds were sent out and grown to whips cheaply and sent back !!

I know that a publicity stunt intending to give children acorns to grow wasn't checked for provenance of the acorns until the last minute. A local supplier is one thing, but locally sourced seed is another.

Aye. The Larch die back affects the Asian Larch - our native European Larch is much less affected. And if I'm right in saying the Larch and Ash die backs are linked (neighbour spent 30yr in the forestry, the last 10-12 years was combating die back). Its too late to do anything about what's here, but this country needs to take a hard look at itself and just importing everything.

Rhododendron is the bugger... it can contract/spread the disease but does not show any signs. Most estates up here are wiping rhododendron out to combat the situation.




There shouldn't be any surprise of the damage which can be done - seen it all before with Dutch Elm. Funnily enough, we've had a bit of forestry done here over the last 6 weeks. The tree cutter felled a massive Elm which although is as dead as a dead thing is showing no signs of rot... its now on my firewood heap

apologies for a slight hijack of the thread, but as mentioned earlier , I’ve noticed a worryingly numerous amount of walnut trees with shrivelled, black leaves, recently. Is this fungal and terminal? Sorry, no photos.
As an aside, we did a lot of work with the forestry commission, a number of years back, when chalara first reared its ugly head. They planted thousands of ash plugs, grown from seed, collected from around the uk. The idea was to find a resistant strain and use as breeding stock for repopulation. I haven’t ever heard any results, but I guess the trials are ongoing.

Good luck splitting that elm?

Screw splitter will handle it no problem. Cut and split hundreds of dead elm in the 70’s sold for furewood

My friends walnut tree suffered the same signs after a hard frost we had 10 days ago, maybe you had the same frost -3 or -4.

Don't worry about me... I'm used to tackling seasoned Beech.


I have my ways

That’s a possibility
