Need advice for my new climbing roses

Hello!
This spring I planted 2 climbing roses in large pots to grow on an arch. I need advice now how to care for them in autumn. Should I prune them? They are about 80-90cm tall. Thank you.

 

Hopefully my valued friend Wise Owl will agree.

Roses although much loved, can at time be a bit of a pain in the neck.

Some. Depending upon what rootstock they have been grafted/budded. Will produce new shoots low to the ground. Others tend to race away, resulting in perhaps having a rose some 3,4,5feet tall with bare main stems and then then the leaves and flowers. I can fully understand folk, not wishing to cut down their beloved rose. Sadly. This is a must. If left. You end up with the roots and your neighbour five doors away have the flowers.

So you have to start and go on at times sacrificing much. There are so many illustrations available.
Perhaps it is a good idea to adopt a special frame of mind. Rose growing is a kind of lifelong ordeal. So however, wherever planted. A climbing rose must have some support.

So the basic program is. To provide suitable support. This usually is wires fixed to a wall and at intervals of say 24" the next wire fixed horizontally. Now comes the crunch. Lets say your plant has kept its basic three main stems. Take the left stem and gently bend it so as to run along the first wire. Secure it and at a suitable bud/joint sever it. Now take the center stem and temporarily tie it to the highest wire it reaches. Now take the outer stem and tie it to the wire halfway between the lower and top wire. Tie it in and give a bud or two and cut. Now return to the centre stem. Try and triangulate the outline. Tie in and cut. Hopefully at each level the stems will produce new shoots that can be trained in. Hope this helps.

 

Thank you very much. I'll try to do my best.

 

Mike, I wish you lived nearby to show me how to do it properly.

 

Thank you all for your recommendations.
