Causes and treatments for yellow leaves of bulbous begonia

1. Unsuitable soil

1. Reason: The yellow leaves of the bulbous begonia may be because the soil in which it is grown is not suitable for its growth. If the soil is underfertile or compacted, it may grow poorly and its leaves may turn yellow.

2. Treatment method: At this time, you need to replace the flower soil. First prepare some loose, breathable, thick, weakly acidic new soil, and spray it with disinfectant. Then take the plant out of the old soil, use scissors to cut off the rotten roots and yellow leaves, and then plant it in new soil.

2. Improper light exposure

1. Reason: It is suitable for growing in a semi-shaded position with moderate light intensity. If the light in the place where it is grown is too strong, it may cause it to grow poorly and its leaves may turn yellow.

2. Treatment method: The plant needs to be placed in a semi-shaded location with moderate light duration and intensity for maintenance. It will return to normal after a period of time.

3. Excessive watering

1. Reason: It likes a humid environment, but is not resistant to waterlogging. During cultivation, if you water too much, water will accumulate in the soil. This will cause its roots to become waterlogged and unable to absorb water from the soil normally, resulting in yellow leaves.

2. Treatment method: Remove the plant from the original culture soil and cut off the rotten roots and yellow leaves. Then put it in a ventilated place and wait for the wind to dry the cut ends. Then plant it in a well-drained culture soil and take good care of it.
