Q.Oleanders in Freezing Weather
It will get to freezing tonight in NW Houston and in the upper 20’s Tuesday and Wednesday. I have planted a dozen oleanders around my new pool. It is our first winter with oleanders and I need them to survive. Do they need additional covering? Also, could I enhance their growing with any fertilizer? They are composted and mulched, and they have a beautiful maroon red flower when they bloom. Thank you.
