No. 32: Prune rambler roses
A rambler rose trained up a wall is subject to a simple enough pruning regime. Have a good look over the whole thing and you’ll see that there are distinct old and new shoots. Untie the shoots and lay the complete structure on the ground. Cut out entirely a third or so of the oldest, thickest, woodiest and therefore least productive shoots. You may need loppers in order for your will to prevail. Then, shove the framework back up onto the wall and tie in each shoot to the wires, spacing them out elegantly while you have the opportunity.
