How to care for Phalaenopsis orchids after they finish blooming, and in what situations should you not fertilize?

As everyone knows, growing flowers requires patience to do well, and Phalaenopsis orchids in particular need careful attention. However, when growing Phalaenopsis orchids day to day, a question often arises: do they still need extra fertilizer while in bloom?

Generally speaking, once a Phalaenopsis orchid has successfully entered its blooming state, it no longer needs extra fertilizer, because the very principle of its ability to bloom is that it already has enough fertilizer to flower. If you fertilize it as usual at this time, it may instead have a negative effect on the plant's growth and blooming. Although orchids need a moderate amount of fertilizer during their growth period to promote growth, this does not mean that fertilizing is a cure-all.

If we analyze the reasons in detail, first, during the blooming period of a Phalaenopsis orchid, nutrients have already been supplied to the flowers, so it is no longer in a state where it needs more nutrients in order to bloom. Therefore, even if a flower lover fertilizes at this time, the plant itself will not absorb the nutrients; the leftover nutrients will be absorbed by the soil and accumulate at the bottom, which in the end can easily develop into root diseases, such as the common root rot.

Second, even if after fertilizing the flowers are willing to take it up, the flowers will ultimately become abnormally large and plump, making the viewer feel that the form of the whole plant is abrupt. If it were really allowed to develop to the point of losing its original form and beauty, that would truly be a pity for its elegant flower posture and unique flower color. Therefore, it is recommended that during the blooming period of a Phalaenopsis orchid, do not apply excessive fertilizer, so as to maintain its original flower posture and beauty.

Finally, it should be noted that, apart from it being unwise to fertilize after a Phalaenopsis orchid blooms, even during non-blooming periods you should fertilize cautiously according to the situation. This is because excessive use of fertilizer will cause the plant to lose its ecological balance, making it prone to root loss and other problems. Therefore, when caring for a Phalaenopsis orchid, it is recommended to learn to alternate between tension and relaxation and to control the amount of fertilizer reasonably, so as to ensure the plant's healthy growth and blooming. In short, when a Phalaenopsis orchid is in bloom, you must absolutely not fertilize it; excessive fertilizing may lead to bacterial infection of the roots.
