Growing roses from tiny bare-root cuttings into a flowering wall: go heavy on the base fertilizer, and the canes will reach two meters

I got a small courtyard at the beginning of the year, and climbing roses were a must. Since I wasn't going to move in right away, I bought them all as tiny cuttings. I didn't go for many varieties, just Red Dragon, Pink Dragon and Pink Wood. This is how the tiny cuttings looked when they first arrived.
Potting them up, I was a bit heavy-handed and straightened them all out...
Pink Dragon and Pink Wood....
Red Dragon
In April I planted them in the small courtyard. I added a fairly generous amount of base fertilizer..... and then, they exploded..... They made it through the height of summer. Since they started as tiny cuttings, they didn't put out many new shoots, so last week I went over and laid the canes down horizontally, hoping to get a few more side buds in autumn and aim for a small flowering wall next year, haha.
Pink Dragon bloomed little but grew the most canes. They're already 2 m long. Once I move in, I plan to remove the row of holly behind it and turn it into a wall of flowers.
Pink Wood has very soft canes, so I'm planning to put it on a flower pillar. It had autumn blooms, but they looked bad, so I pinched them off.
Here's a spring bloom to headline the post.
Red Dragon had summer blooms, but they looked bad, so I pinched them off to save nutrients for cane growth. I'm planning to train it into a shrub form or just let it be a flowering wall, haven't decided yet, so I'm just letting it grow.
The terrace faces due north, and the climbing roses are all planted in the sunniest spot. In summer I have to put up shade netting. Three varieties are enough; climbing roses are all very vigorous varieties, and I don't want to grow too many. After growing them for over half a year, aside from fertilizing and weeding, I haven't sprayed any chemicals. I probably won't be adding any more roses.
