- Examine the tree for signs of recent drought.
Likely causes
Natural Shedding
Most likelyHow to tell: The needles turning yellow or brown are located deep inside the tree near the trunk. This happens in the fall and is a normal part of the tree's life cycle.
What to do: No action is needed. You can rake them up if you prefer, but they also make a great natural mulch for the tree.
Needle Cast Disease
PossibleHow to tell: Needles are dropping prematurely while still partially green or showing distinct spots. This often happens after a very rainy or humid season.
What to do: Clean up all fallen needles from the ground to prevent the fungus from spreading. Prune away branches with poor airflow to help the canopy dry out faster.

When to worry
Worry if you see green needles dropping in large numbers or if the tree is losing needles from the outer tips. This indicates a health issue rather than natural aging.
Stopping it coming back
Keep the area beneath the tree clean and avoid overhead watering, which can encourage fungal growth. Ensure the tree is planted in a spot with full sun and good drainage.

Questions people ask
- Will my tree go bald?
- A healthy Lodgepole pine will always have a full canopy. If it looks thin, it is likely reacting to environmental stress or a fungal issue.
- Can I compost the fallen needles?
- If the needles are healthy, they can be composted. If they show signs of fungus or disease, it is better to bag and dispose of them to prevent spread.
