Horticultural aide memoire Prune rambler roses
To get the most from a rambler rose, particularly one trained against a wall, it should be pruned now. The regime is simple enough. Look at the shoots tied to the wall and the new ones rising from the base. The object is to cut out the oldest third of shoots right down to the ground and then to tie in the new shoots, thus exchanging the old for the new. The older shoots will be thick and require loppers to cut them. Then, chop the rest of each shoot into handy lengths for removal. Tie in the new growths.
