It appears that British Ash trees are genetically different to European strains, and are much more resistant to it.
I’m always looking at the trees around North Wiltshire, and I’ve yet to spot any showing signs.
Thing with Ash is it sets seed very easily, it’s like a bloody weed in some places, hundreds of saplings sprouting anywhere they can.
Highly unlikely to be last years, ash tends to shed 99% of its leaves in one go on a cold snap.
Chalara does cause new growth to burn and curl as you have described and young trees are more vulnerable.
As CZ mentions, there is some genetic diversity, most outbreaks are in imported root stock. Incidents are worth recording, but not necessarily the slash and burn there was for elm. Potential loss of resistant genetics.
Hi. I saw some obviously sick ash saplings this week, about ten feet high and with the new leaves twisted and blackened. Assuming it’s that new disease, can I be confident that the landowner would do the right thing, or should I report what I saw? And if so, to whom?
