Citrus Winter Care on indoor citrus
What's Happening
Citrus trees enter semi-dormancy in winter, slowing growth and reducing water and nutrient needs. Indoor conditions during winter present unique challenges: heating systems reduce humidity to 20-30%, cold drafts from windows cause temperature shock, and reduced light intensity limits photosynthesis. These stressors compound to cause leaf drop, pest outbreaks, and root problems if care routines aren't adjusted seasonally.
How to Fix It
- 1
Reduce watering: Allow soil to dry 2-3 inches deep between waterings; dormant roots absorb less water
- 2
Increase humidity: Use humidifier or pebble trays to maintain 50%+ humidity despite heating
- 3
Maximize light: Position in sunniest south-facing window or add grow lights 12-14 hours daily
- 4
Avoid temperature swings: Keep away from cold windows at night and heating vents during day
- 5
Reduce fertilizer: Apply at 1/4 strength monthly or pause entirely November-February
- 6
Monitor for pests: Dry winter air favors spider mites and scale; inspect weekly
How to Prevent It
Gradually reduce water and fertilizer in fall as light decreases; maintain stable temperatures between 55-70°F; increase humidity proactively before heating season begins.
