We need to know if the white pine trees in the twin cities are going pollinate (pop) soon. I want to understand how to identify when the tree is ready to pop. I have to keep the windows closed or the entire house or the inside will be dusted. We guess the big tree in our front yard is over a 100 years old. And don’t know how to tell it’s ready. Do you have any pictures showing me what it looks like before popping? Thank you for a referral or any information you can provide. Sent from my iPad Thanks, Deb Carroll
