Question From: S. Marcus - Vacaville, California, United States
Q: Why would a huge pine tree start dropping large clumps of pitch? The tree is approximately 30 years old
It's probably the larvae of a moth making holes in the tree. The tree is at risk and also under stress making it vulnerable to deadly diseases that are attacking pine. If it were my tree and I hoped to save it I would get an onsite inspection from a professional. To find a certified arborist in your area go to www.tcia.org and enter your zip code. Good Luck, Nancy
