Meyer Lemon Leaf Drop in Seattle: Cold, Light, or Pot‑Bound?

The Situation

Two Meyer lemons in a shed lost many leaves after a cold snap. The owner wonders if a halide light would help, given Seattle’s short winter days.

Normal Citrus Behavior

Citrus naturally shed inner leaves in late winter to make room for spring flush. However, excessive drop signals stress.

Check These Factors

• Cold injury: If stems are green, recovery is likely.
• Watering: Keep soil evenly moist—never bone dry or soggy.
• Pot size: If roots circle the pot, repot into a 2‑inch larger container.
• Fertilizer: Use a slow‑release citrus formula; avoid high‑salt products.
• Light: A halide or LED grow light (12–14 hrs/day) helps maintain foliage in low‑light winters.

Action Plan

Scratch bark—green underneath means life. Address water, pot size, and nutrition first; add supplemental light if drop continues.
