If it is watered, the old leaves will not change obviously, but the young leaves will turn yellowish, and in severe cases, the roots will rot and the plants will die.

Solution: watering the carnation flower must be appropriate, too little watering can appropriately increase the watering times, and if the watering is too much, the water should be discharged in time, and the flowerpot can be placed on the newspaper or peat, so that the excess water can be absorbed, or it can be replanted directly.
