What to Do When Bonsai Ficus Leaves Turn Yellow? Causes and Solutions
A ficus bonsai is a sculpted landscape that symbolizes vitality, so maintaining the continuation of its living growth becomes the inevitable purpose of its care and management. However, yellowing leaves often occur during actual cultivation, and there are many causes of yellowing leaves in ficus bonsai. Let us take a look together below at what to do when ficus bonsai leaves turn yellow!
Water yellowing
When ficus bonsai young leaves turn dull yellow and lose their luster, the old leaves show no obvious change, the branches are thin and yellow-green, and the new shoots shrink and stop growing, it indicates overwatering. Remove the plant from its pot, place it in a ventilated, cool spot to let the soil ball dry out on its own, then put it back in the pot.
Drought yellowing
The yellowing of a ficus bonsai from lack of water differs from the yellowing from too much water. The yellowing from lack of water shows as leaf tips or edges becoming withered and dry, with old leaves turning yellow and falling from the bottom up, but new leaves growing relatively normally. Just pay attention to watering thoroughly and deeply.
Scorch yellowing
Strong direct sunlight hitting a ficus bonsai easily causes leaf tips and leaf edges to wither, and yellow spots appear on the sun-facing part of the leaves. Simply move it to a shaded spot.
Lack of light
If ficus bonsai leaves are kept in a shaded environment for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, so the whole plant's leaves turn yellow and then drop. Adding light can prevent this problem.
Fertilizer yellowing
Yellowing of ficus bonsai leaves caused by too much fertilizer or excessive concentration shows as dry brown tips on new leaves; generally the leaf surface is thick and lacks luster, and is uneven and not smooth, while old leaves turn scorched yellow and drop. Stop fertilizing immediately, and in severe cases flush out some of the fertilizer with a large amount of clean water.
⟦NL>Lack of fertilizer
Lack of fertilizer in a ficus bonsai shows as young leaves becoming lighter in color, appearing yellow or pale green, while old leaves remain relatively normal or gradually turn from green to yellow. Check the potting soil; if there is caking, replace the soil, usually apply light fertilizer frequently and water with some alum water at the appropriate time.
