From time to time, the leaves of the plant shed, followed by new leaves. Do not panic when the leaves fall, if the leaves of the plant start getting damaged they should be removed. If weeds are growing in the plant, then remove it, otherwise the growth of the plant stops. And if insects are found in the plant, they should be treated with neem oil or insecticide at the appropriate time.
Yellowing of the leaves of the plant is sometimes caused by over watering. If you are adding water daily, then water should be less, otherwise, the roots of the plant get fungus and the plant starts getting spoiled.
