1. Yellow leaves short of water: In the early stage of water shortage, the new leaves of the rich tree can't see other problems except some wilting, but the old leaves at the bottom will dry up from the tip of the leaf, and then gradually spread until they fall off. If it is not handled properly, the new leaves will wither gradually and then dry up until the whole plant dies due to lack of water.
2. Yellow leaves after waterlogging: In the early stage of waterlogging, the old leaves of Fugui tree have no obvious change, but the new leaves will become dim and dark yellow, then yellow, and the new buds will be very thin and will not grow. If waterlogging is allowed to continue, the rich trees will rot, the roots will not absorb water, and there will be a phenomenon of yellow leaves lacking water.
3. Fat hurts yellow leaves: rich trees don't like fat. If you fertilize too much, you will get fat. The fat damage of Fugui tree is characterized by dark brown tip at the beginning of new leaves, different thickness and uneven wrinkled leaves. Later, the old leaves will turn yellow and then fall off. If left unchecked, the whole plant will burn its roots and die.
4. Iron deficiency yellow leaves: the growth of plants is inseparable from various trace elements. Besides nitrogen, phosphorus and potassium, iron also plays a very important role in the growth of rich trees. If you find that the leaves of the rich tree are thin and yellow, but the veins are still dark green, and the whole reticular veins are very obvious, it is probably iron deficiency.
The above are the common reasons that lead to the yellowing of the leaves of the rich trees. You can judge according to the actual situation. If you are not sure why, I suggest you consult a professional or a flower planting expert.
