Thank you Abdul Haque hi, but few days back only I applied cow dung and unused tealeaves in the plant.

Excessive watering can cause the soil to turn yellow all the time if the soil is always wet and stagnant or if the soil is always dry due to lack of water. Now there is no need to apply any more fertilizer Parwani Family

Thanks Abdul Haque . I will take care. May be it is because of less watering. I water it once a week or so.

Parwani Family apply some micronutrients along with good farm yard manure
