Question From: CALIFORNIA
Q: Is it safe to trim a large white pine tree any time of year in warm climates? (I live in Southern California). It's overgrown and branches are laying on my roof.
White pines are usually pruned in late winter or early spring here in Michigan. According to Google there are 6 fires currently burning in Southern California. I suggest you get the advice of a certified arborist as to how to prune your tree. It may well be a fire hazard. Best And Happy Yardening, Nancy.
