Maybe the UK should plant more....

@Squaredy   far too many non natives in this country as it is. As a UK plan you also have to take into account flooding events - where trees can assist. K

Elm.  

 

Plant those that have some proven genetic resistance to Dutch Elm Disease.  Occasionally I'll see a mature specimen alone in the landscape - and what a magnificent beast it is.

Is there a variety of walnut that is hardy enough for the UK? I have a few walnuts in my woodland, planted by the previous owner, and most springs they get damaged by frost. This year virtually all the fresh leaves have been killed off.

 

Obviously walnuts do grow but can you guarantee a good crop in the uk compared to say France or further south?

some walnuts do crop in the south

What wrong with non natives if they grow well and provide useful timber.

 

I'd like more sweet chesnuts coppice plantations but maybe climate isn't viable for them in north?

I know, but someone I know with a plantation of walnuts grown for the nuts often looses the crop to frost.

 

I had a quick search to see about growing walnut timber trees and it seems frost and poor form are widely accepted as problems and new cultivars have been developed over the last few years to overcome this. Perhaps people are now planting them.

There is a large walnut near me ( several actually that border the old Lavant/Midurst railway line ) . This tree is a biggun and has self seeded , with the help of the rooks , several young trees about 8 foot in height . All these youg trees have very blackened and shriveled leaves . I don't know if its early frost or recent drought but they don't look happy . The biggun however seems fine .

Think provenance choice of species planted is important as so much variation within species prorbably often overlooked?

 

Mentions a late flushing walnut cultivar that reduces frost damage:

 

Quote

Walnut (common walnut, Juglans regia
and black walnut, Juglans nigra)

Both species produce very valuable timber, but are
susceptible to unseasonable frosts in autumn and spring.
Hybrids of the two species are now also available and
these exhibit very good form and vigour combined with
late flushing. Nurse crops are also potentially important for
the successful cultivation of walnuts for timber.
Provenance/progeny trials of J. regiawere established by
Northmoor Trust at Little Wittenham, Oxfordshire, in
1998 (Hemery, 2001). Results after five years demonstrated
the importance of late flushing as annual height growth is
reduced by frost damage. In the trials two French
provenances, of Tadjikistan and Iranian origin, and a
Slovenian provenanceperformed consistently well over the
three sites (Hemery et al.,2005).

Recommendations for walnut

• Use planting material that is known to perform well in
an environment as similar as possible to the planting
site.

•In general seek late flushing provenances, for example
the French variety of J. regia‘Lozeronne’.

• Hybrids between J. nigra xJ.regia,developed in
France, should also be considered.

Also the selection of a  seed source from a cultivar of a species selected for the timber quality plus climate and soils.

LOL thanks for that Nepia.  Still is a beautiful tree for sure.

It used to be a lovely view driving under it with its lights on. Dunno if they still work in the winter
