Needles are turning yellow
We just moved in a new house (Long Grove, IL - Northwest suburb of Chicago) this June. The previous owner had planted a quite few pine trees around the house.
Just recently we noticed the needles of these pine trees are turning yellow. Please see the pictures.
My questions are:
1) What kind of pine trees are they?
2) Are they normal at this time of the year with yellow needles? or they have some diseases?
Your answers will be greatly appreciated.
