could you please tell me how to prepare this rose tree for winter ?

In early July just after bloom finishes, completely cut allcanes that have had blooms down to the ground. Tie up the new shoots that have sprung from the ground. They will grow enormously and bear next years flowers. Do every year. You'll have to wait till next year now. Wear very long gloves and get help

don't do a thing. it grows wild around town here, it was the rose that was planted on railroad banks to keep folks off the tracks. it grows and grows when it stops, nobody knows. no one does anything for it. i suspect there are times when zealous people try to kill it by pruning it and it comes back anyway. no one winterizes or automatically prunes it and it is always smiling back the next year.

This rose is very susceptible to Mildew! It's a disaster!

I just dug-up a plant of 'Super Excelsa' and gave it to a neighbour, I found it rather too boring. I planted 'Cerise Bouquet' in its place.

How is Cerise?

It is still quite small but growing well. I grew it from a cutting I stole from a garden in a nearby town. I remember I saw it flowering in the summer, this strange half rambler half shrub, full of double pink flowers. Individual flowers not a mass of blooms smothering the whole plant like 'Dorothy Perkins'. I returned in the autumn to commit the crime. I don't think there will be flowers this year but it is making good growths for next season.

Andrew: Thank you for the info. on nutrient deficiencies you sent to me. How do you root cuttings in your cool climate? What type of soil medium? How do you root in high-rain weather? Thanks for any info. I tried rooting indoor this past zone 5a winter, and only 3 rootings made it . perhaps my house is too cold (57 F or 14 C at night).

You are most welcome.
Ideally in October I take lengths of stem about 30cm long and bury them about two thirds their depth, Using a spade I make a V shaped hole that I refill with sharp grit. Generally they will have rooted by the spring but I leave them in situ until the following autumn when I pot them up and grow them on. If I had a green house then I could do the same in a deep pot. I get a reasonable success rate except Gallica which won't root this way at all. This is standard proceedure for any type of shrub or tree.
In general I get a zone 7 winter, In parts of Europe with colder winters I have seen people using my technique but they place a coffee jar over each cutting

Thank you & much appreciated. Sharp grit is the same as our coarse sand/or paver's sand. I tried that one year but we had so much rain which eroded the sand ... will try putting a glass jar over to block out the rain.

It is courser than builders' sand, the sand you would use to make cement, but not so course as balast that you would use for concrete.
