1. Natural declineWhen we see our white calla lilies withering, we become very nervous, wondering if they are dead. In fact, if other breeding conditions are normal, there is no need to worry too much. This is a very natural phenomenon. After it blooms, it will slowly turn green, and finally it will be the same color as the stems and leaves. The yellow inflorescence inside will gradually turn black. This does not mean that it is mutating, but is just the normal metabolism of the flower blooming and falling. Solution: If you are very worried, then we can use some methods to deal with it. Generally, we can cut off the entire inflorescence from its base to prevent them from consuming too many nutrients of the plant, thus affecting the next flowering. 2. Encounter with pests and diseasesNo matter what plants you grow, you must pay attention to diseases and pests. Just like if the white calla lily dies, it may be caused by damage from pests and diseases, because when it is attacked by such diseases, the plant will be seriously affected, and the flowers that have just begun to bloom may fall directly. From this point of view, the problem of pests and diseases cannot be underestimated. Solution: When there are no diseases or pests, we must always pay attention to them and prevent them in advance. As long as we find them, we need to catch the insects in time, or spray them with some pesticides. 3. Improper fertilizationIf you fertilize it excessively or insufficiently during its growth, especially during its flowering period, it will also cause its flowers to wither, because either the nutrients provided are too abundant and the flowers are burned to death, or the nutrients are insufficient and flowering is restricted. Solution: Generally, you should apply some fertilizer in advance before flowering, preferably something that is conducive to flowering, but not too much. If there is too little fertilizer, you can add a little bit appropriately, so that it can provide it with sufficient nutrients and facilitate flowering. |
