Check these first
- Look for browning at the very tips of the branches.
- Check if the spots are spreading to the stems.
- Inspect the plant for signs of high humidity or trapped moisture.
Likely causes
Juniper blight
PossibleHow to tell: You will see small, tan or brown spots on the needles that eventually spread to the stems. The tips of the branches will start to die back and turn brown.
What to do: Prune away all infected branches, making sure to cut back into healthy wood. Disinfect your shears with alcohol between cuts to prevent spreading the fungus.
Fungal leaf spot
PossibleHow to tell: Small, dark spots appear on the needles, often surrounded by a yellow halo. This usually occurs during periods of high humidity or poor air circulation.
What to do: Improve air circulation around the plant by thinning out dense branches. Avoid overhead watering to keep the foliage dry and reduce fungal growth.

When to worry
It is serious if the spots are spreading rapidly and causing entire branches to die back. Minor spotting on a few needles is usually manageable with better care.
Stopping it coming back
Always water at the base of the plant rather than over the foliage to keep it dry. Provide plenty of space between plants to ensure good airflow.

Questions people ask
- Can I spray the spots with water to clean them?
- No, avoid getting the foliage wet, as moisture encourages fungal growth. Use a dry brush to gently clean the needles if needed.
- Should I use a fungicide?
- Fungicides can help, but they are most effective when combined with proper pruning and better airflow. Focus on removing the infected parts first.
