indoor decline on Citrus
Quick answer
If your Citrus has indoor decline, the most likely cause is: Most citrus bonsai die indoors because they were bred for outdoor growing and need a cold dormant period. Without this, they become leggy, drop leaves, and fail to fruit. Even tropical citrus need distinct temperature drops and shortened photoperiods to trigger dormancy.
Start here:
- 1. 1. Move citrus bonsai outside every spring when night temperatures exceed 50°F
- 2. 2. Acclimate gradually: start in shade for 1 week, then expose to morning sun
