What is pine tree needle drop? Is it normal for pine trees to drop needles? 

Needle drop is the natural process whereby trees shed their needles. However, it can be caused by one of two things. On the one hand, it can be a completely normal cycle for the tree to experience, however, it can also be indicative of a disease or drought. If the case for your tree is the latter, you will want to be in touch with our team ASAP for a consultation.

Evidence of needle drop does not have to be a bad thing. This process can be a natural occurrence for interior needles that are between two to four years old. In this case, it is a natural phenomenon and nothing of concern. However, if it is more noticeable than in other years, it could be the result of something more significant like disease or drought.
