During the fall, conifer trees shed older needles to make room for new needle growth. Some conifers shed more needles than others, and some varieties shed all of their needles annually. A conifer shedding its needles in the fall is nothing to worry about, the tree is perfectly healthy. If the conifer sheds needles throughout other parts of the year, however, diseases and insects may be causing the needle drop.
Key Takeaways:
- Just as deciduous trees shed leaves in the fall, conifers shed their needles.
- Some conifers shed dramatically, essentially losing all their needles, while others may retain several years worth of needles, only losing a few at a time.
- Conifers that shed at times other than September and October, could be experiencing a parasitical invasion.
