Dwarf Meyer Lemon Losing Leaves After Moving Indoors

A North Alabama gardener moved a potted Meyer lemon indoors when night temperatures hit the 40s–50s°F. Since then, leaves develop yellow spots and drop, though the tree has started flowering.

Why the Leaf Drop?

Citrus trees naturally shed leaves when transitioning to lower light and humidity indoors. The tree is reallocating energy to flower and fruit production—it can't support a full canopy and reproductive growth simultaneously.

Key Mistakes to Avoid

• Bringing it in too early: Meyer lemons tolerate temperatures down to freezing (32°F). Only hard freezes (below 28°F) cause damage.
• Indoor pests: Extended indoor stays increase risk of spider mites, scale, and aphids.

Better Strategy

1. Keep the tree outdoors as long as possible; protect only during hard freezes.
2. If indoors, place in the brightest window, use a humidifier, and monitor for pests.
3. For organic pest control, try Atomic Grow or insecticidal soap.

Leaf drop is usually temporary; new growth will emerge when conditions improve.
