What to do if the leaves of kumquat tree turn yellow

1. Physiological leaf fall

If no wrong maintenance measures are taken during the maintenance process, but its leaves still turn yellow, it means that this is most likely a natural phenomenon of leaf fall. The fallen leaves at this time are all in the middle and lower parts of the branches. It is a natural phenomenon for the old leaves to turn yellow. New leaves will grow next, so there is no need to worry too much.

Solution: You should use loose, breathable soil with good drainage properties. There should be no water accumulation in the pot on rainy days. If the surface of the soil turns a little white, you can water it. Each time you water it, you must water it thoroughly, not just sprinkle a little water. If the weather is very dry, water it more.
