Do I need to protect my hydrangea from freezing temperatures?
We have been experiencing above-normal temperatures here for the past week-and-a-half. One of my hydrangea bushes (Endless Summer) that I planted last year has just begun to bud, and a few of those buds have even opened up and are starting to form leaves (the other Endless Summer hasn't developed any buds yet). The NWS is forecasting a storm to move through here this weekend, and right now they are saying that the low on Monday will be 30F. Will I need to protect the plant, or can the leaves withstand a light freeze?
