Stove - wood or pellet?

Rare to see seed on an Elm. Most regrowth is from surviving roots hence their genetic vulnerability.

Did you? How interesting. You were wrong, again, so alli s well with the world.

[John Williamson]

And it's now been found in Carmarthenshire:-

suspect that it's come in on imported nursery stock.

[Alan Braggins]

Though from the same page: "Local spread may be via wind, rain splash or even transmission by insects."

But there's no definite link to specific insects the way there was with elm bark beetles.

There's been no evidence of insect vectors from the reports from Denmark, I suspect that any transmission by insects is about the same as transmission by mammals including biped;. accidental contact with spores later rubbed off against trees.

[The Natural Philosopher]

Indeed.

90% of all birch trees die from birch fungus attack in the end. Or at least infected with it.

bit of damage and its in.

I too am planning to install woodburners, in a couple of disused fireplaces I'm going to bring back into use. I'll probably need to fit stainless steel flues. Do all flues & burners have a standard gauge or do I have to worry about matching them up? I'll probably be going for quite small burners, about 3-4kW at most. Recommendations welcome.

[Sorry I posted this to a new thread too before seeing this one.]

Not in Brighton or Edinburgh.

They tend not to get old enough here or don't like the cold.

Both need 150mm flues venting above the eaves so no difference from that point of view.

Well I suspect the elms you remember were the clone Ulmus Procera, which didn't set viable seed in this country, and where it did I suspect it's progeny would be classified differently.

The reason it doesn't grow large (rather than old) is probably to do with the young trees inability to host beetle breeding galleries in the phloem.

My wife has grown seed gathered from a roadside in Brighton and I cannot distinguish one tree from english elm now it has grown to 5 metres tall.

I have recently assisted in felling a large healthy wych or smooth leaved elm at Brighton football ground and even though it was a resistant species I could plainly see the typical tylose (blackened bodies that block the vessels in reaction to the DED) in several earlier annual rings, suggesting it had overcome infection. It was english elm's tylose production in reaction to the fungus and its dependence on the vessels in the current annual ring that caused it to kill its own crown but the rootstock could live on.

Yes. They are still here. The surviving roots send up fresh shoots which grow for about 15 years and then die.

Did they ever find a truly resistant variant?

The only Wych here is in hedgerows and subject to annual flailing.

All the more reason to plash the hedge every 12 years ;-)

I don't think so, leastways not one that looked like english elm
