Baltimore, like much of the United States, has been experiencing an unusually warm month and a fitting conclusion to what is shaping up to be the Earth’s warmest in over 1,400 years.
The mild temperatures aren’t universally reassuring, however. Many gardeners are concerned about the effect of “Warm December” on their plants.
At the New York Botanical Garden, azaleas and viburnums are opening their buds months early.
For many plants, especially non-native ornamental plants, the long period of abnormal warmth has triggered the process of bud break. This process, in which leaf and flower buds emerge from dormancy, is usually triggered by the climbing sun and longer days of late spring. –(December 2015)by Vincent Vizachero for Blue Water Baltimore.
