Answer: Oleanders should not be cut down to a foot each year. While they will grow back, they won't get as tall as if you simply shear them or selectively cut the branches back. Everytime you cut a main stem, two new stems will grow. To keep mine renewed and full and bushy I reach into the center of the plant and snip branches off at various heights. As new growth appears it will fill in the center of the plant. The outer branches can be pruned back, as well. I prune mine each time it has finished flowering. Mine is about 8' tall now and 5' wide and it was planted 3 years ago. I think this same pruning method will work for you, too. Good luck with your oleander.
