Q. It looks like it was cold enough at the end of October that it caused some cold damage on our porter weed. When should we move the bougainvillea, hibiscus and other cold sensitive plants into shelter?
A. As the damage on your Porter weed showed tropical plants can be damaged if temps fall below 40 degrees F. That last cold spell snuck up on us. Watch for another prediction for temperatures to fall below 40 degrees and move the plants to shelter. Another route might be conservative and just to move the cold sensitive plants to shelter beginning in mid-November.
