Q.Frozen Oleanders
We live in southern New Mexico and we had a very cold spell several weeks ago (-8 at night and 7 above in the day for 3-4 days). We have oleanders that really look bad. Do we cut them back? The leaves are cripsy with no new growth that we can see. We lost several cactus and one butterfly bush looks pretty bad, but it is getting new green leaves.

Check if the stems are still alive. If the stems are still alive, the leaves will regrow. This article will help you with that: https://www.gardeningknowhow.com/plant-problems/environmental/how-to-tell-if-a-plant-is-dead-and-how-to-recover-an-almost-dead-plant.htm Anything that is dead, trim away. Anything that is alive, leave it be so it can regrow leaves.
