ID and advice please

You can use sbk brushwood killer, drill a few holes with as wide a drill bit as you can, about 1/2"- 1" deep, fill with sbk, cover with some plastic and wait.
I have used some petrol mixed with a small amount of engine oil just brushed on, and found this to be quite effective, the picture could be some sort of blue spruce, Derek.

Yup agree...

That is a beautiful tree, Steve. I want one too! Have you any idea how old this one is?

No idea Gattina. I would like something similar for my garden and I scouted this one in our village! Derek and MoonG, thanks for your replies

Yep, Steve, it's a Colorado Blue Spruce (Picea pungens), probably a named variety, judging by the regular growth habit.
Gattina, If your summer temps get much over 38º C for much of the summer, it will likely give you troubles. Blue Mt. Atlas Cedar (Cedrus atlantica 'Glauca') is an adequate substitute, but will need creative pruning to match the form of Steve's specimen.

Gosh, Tugbrethil, don't you know a lot? Thank you for that.

After I commented on this, I read where you said that you were in a cherry growing region. Anywhere cherries will grow, so will a Colorado Blue Spruce, so no worries! : )

That's quite strange and really interesting - they are such different trees. I shall have to start looking for tree nurseries (there are quite a few for the grand gardens of the rich people) over the border in Tuscany, and see if they can supply one. They tend to concentrate on columnar cypresses, olives, oleanders and umbrella pines, but fingers crossed! First the dictionary.........

Well, Colorado Blue Spruces tend to suffer in summers above 37º C, though nights below 30º will help, and cherries tend to form double fruit, and/or crack, in hot very hot summers, too. Usually commercial cherry growers avoid places where spruces would suffer.

Most of the commercial cherry growers are down in the river valleys - slightly cooler in summer, and warmer in winter, but much damper all round.
