Why do some trees shed their leaves?
Trees like birch, maple and oak and shrubs like hydrangea that shed their leaves each wintry weather are known as deciduous timber. Their leaves are too vulnerable to live to tell the tale severe cold. But different timber live inexperienced all year. Evergreen timber like pines and firs and shrubs like yew do now no longer shed their leaves in iciness. This is due to the fact the leaves of evergreen timber are lined in a wax-like substance that prevents them from freezing.
