Citrus (Clementine Orange) Leaf Drop After Moving Indoors: Acclimation Strategy

Moving citrus from outdoor sun to indoor light causes massive leaf drop—it's normal acclimation, not death. The tree sheds high-light leaves to grow low-light foliage.

Survival Protocol

1. Maximum sun: South/west window, no obstructions. Supplement with grow light if <6 hrs direct sun.
2. Reduce watering: Water thoroughly when top ¼ of soil is dry. Indoor = less water use.
3. Prune leggy stems: Cut back bare branches to stimulate bushy regrowth.
4. No repot/fertilizer until spring.
5. Misting: Optional, minimal benefit. Focus on light + water.

Expectations

• Leaf drop continues 4–8 weeks.
• New growth appears in 6–12 weeks.
• No fruit this winter; flowers may drop.
• Spring move outdoors = rapid recovery.

Long-Term

Citrus needs 8+ hrs direct sun daily to fruit. Indoors, it's a foliage plant. Consider a dwarf variety (e.g., 'Improved Meyer Lemon') for better indoor performance.
