Certain rhododendrons and deciduous azaleas can survive temperatures as low as -35°F (-37°C). It is normal for some rhododendrons to exhibit leaf droop and curl at around 32°F (0°C).; the lower the temperature the tighter the curl. Leaf movement occurs rapidly and it is reversible as temperature warms.
Although azaleas are hardy plants, able to withstand freezing temperatures, measures still should be taken to protect them from frost. The plants need help adjusting to cold temperatures as autumn turns to winter. Because azaleas have shallow root systems, frozen soil can injure their roots if they have no protection.
how cold is too cold for hanging baskets? If you have plants in hanging baskets or other containers, bring them inside. The following methods can be used to limit frost injury. However, protection for temperatures below 25 degrees Fahrenheit may not be possible.

How do you winterize hydrangeas?
A good way to start winterizing hydrangeas is to lay down a thick layer of mulch over their root area. Straw works well for this.
