Recently a White Pine lost 5 branches, ranging from 1 1/2" to 3" in diameter. We just had a heavy wet snow.  The branches all look as if they have been sawed halfway through, and the rest is broken/split. My landscaper thinks that White Pines naturally break that way and the weight of the snow brought them down. 5 branches, and all looking as if they are sawed halfway through? They didn't hang over a property line, but are in the backyard.  I have attached a few pictures.  Please let me know what you think.
