yellow leaves on Citrus Mitis
Quick answer
If your Citrus Mitis has yellow leaves, the most likely cause is: Container-grown calamondin (Citrus mitis) leaves yellow during the cool winter months when root uptake of iron slows in cold soil, a recurring iron chlorosis that the Edible Houseplants authors flag for every citrus in their collection, including the calamondin chapter that sits alongside the note 'leaves may yellow due to iron chlorosis'.
Start here:
- 1. Hold fertilizer and let nighttime temperatures stay above 60 degrees F (15 degrees C) through the cool months so the root system keeps taking up iron instead of locking it out in cold, wet soil.
- 2. Once active growth resumes, flush the pot with pH-balanced water and apply a chelated iron drench or acidifying citrus fertilizer; the new flush that emerges in late winter will come in green as soil temperatures climb.
