This article will analyze the yellowing phenomenon of Gardenia potted plants and provide corresponding maintenance guides.
Gardenia potted plant yellowing phenomenon analysis1. Soil problems

2. Improper watering
Gardenia is not tolerant of waterlogging. Too much watering can lead to root rot, which can affect the leaf color. Insufficient watering can also cause Gardenia leaves to turn yellow.
3. Insufficient light
Gardenia prefers a semi-shaded environment. Insufficient light can cause leaves to turn yellow, but being in a dark environment for too long can also make Gardenia leaves yellow.
4. Improper fertilization
Too much or too little fertilization can cause Gardenia leaves to turn yellow. Excessive fertilization can damage the Gardenia roots, while insufficient fertilization cannot meet the growth needs of Gardenia.
5. Diseases and pests
