Thanks, Zuzu!
>> Gardeners with limited space may need to prune their roses to keep them within reasonable bounds,
I was wallowing in how big and covered with blooms my monster KO Rose was getting when we thought about moving it to my SO's place (partly to free up my only really good raised bed). I started pruning it so that it would fit into a van, and also so that losing some roots wouldn't make it unbalanced.
That's when I learned that they "should" only grow to 3-4 feet in all directions.
And I noticed that it WAS getting very dense on the inside of the bush, and only bloomed on the outer surface.
Then I saw YouTube videos where gardeners cut THEIR KO Roses down to 18" - 24" skeletons each year! I felt like a Bad Parent. Your article reassures me that I wasn't abusing the rose.
I think I will still push myself to do some thinning-out pruning every year or two, and maybe keep it's height within reach.
Eventually, the desire to grow something in my sunniest spot besides a rose bush may motivate me to prune severely, and root prune, then dig it up and move it. Are they like trees where you might prune 1/3 to 1/2 the roots one year, then move the tree the second year?
