Likely causes
Spider Mites
Most likelyHow to tell: You will see tiny, fine webs between the needles and yellowing foliage. These pests thrive in dry air and cause the needles to fall off.
What to do: Wipe the foliage down with a damp cloth or give the plant a gentle shower. Apply neem oil or insecticidal soap once a week for 3 weeks to clear the infestation.
Sudden Environmental Change
Most likelyHow to tell: The plant drops needles shortly after being moved to a new spot or after a sudden temperature shift. It is reacting to the change in light or draft.
What to do: Leave the plant in one spot with bright indirect light. Avoid moving it again so it can recover from the shock.
