Causes and treatments for yellow leaves of gardenia

1. Excessive watering

1. Reason: Gardenia likes a moist growing environment, but cannot grow in soil with stagnant water. If you give it too much water during maintenance, it may cause root rot and yellow leaves.

2. Treatment method: First, dig it out of the original flower soil, and use a knife to cut off the yellow leaves and roots that have been soaked and rotten by water. Then, place it in a well-ventilated place to dry, and then plant it in new soil with good drainage for maintenance.

2. Flower soil is not suitable

1. Reason: It has relatively high requirements for flower soil. If the flower soil used for cultivation is not breathable enough or is too alkaline, it will cause poor growth and yellow leaves.

2. Treatment method: In this case, the soil needs to be changed. First prepare some loose, thick, breathable, well-drained and slightly acidic flower soil as new culture soil. Then take the plant out of the old soil and plant it in new soil.

3. Apply concentrated fertilizer

1. Reason: It likes fertilizer, but is afraid of concentrated fertilizer. If the fertilizer is not diluted before application, the overly concentrated fertilizer will damage the plant and cause yellow leaves.

2. Treatment method: First use plenty of water to water the flower soil to wash away and dilute the fertilizer in it. Then stop fertilizing for 15-20 days and wait for it to recover.
