When is the most suitable time to fertilize and repot Phalaenopsis orchids?

Many flower lovers choose to give Phalaenopsis orchids when visiting relatives or at a friend's birthday, mainly because they have an auspicious meaning, are highly attractive, and have an exceptionally long blooming period, so the recipient is sure to love them. However, how the friend who receives the flowers should care for the Phalaenopsis orchid becomes a problem. Is there anything beginners should pay attention to when caring for them?

Generally speaking, with normal care of Phalaenopsis orchids, as long as temperature and watering are handled well, it is like solving 70% of orchid disease problems. But for beginners, the hardest part to master is the fertilization step. With the weather now getting hotter day by day, can you still apply foliar fertilizer to the flowers in this situation? And do you have to fertilize the flowers all year round?

Another flower lover also asked: he found that on plants whose growing medium had not been changed, the newly grown leaves were obviously smaller than before, while plants whose growing medium had been changed grew more robustly than before. So can fertilization be used to make those weak-growing plants better?

Regarding the fertilization matters mentioned above, they must be analyzed according to the specific situation. If the flower you are growing is sick, then it is recommended that you do not fertilize for now, because fertilizing at this time may not be absorbed by the flower and may even worsen the condition. But if your flower is completely normal and now happens to be in a vigorous growth period, then you can fertilize normally, because during vigorous growth the flowers have a high demand for nutrients, and normal fertilization can provide them with enough nutrition to make them grow more robustly.

Now let's talk about repotting and changing the growing medium. On plants whose growing medium had not been changed, the new leaves became smaller, while those that had been changed grew more robustly. From this actual situation, it really is time to change the growing medium for the plants whose medium has not been changed. However, changing the growing medium also has its requirements; it is best to do it when the plant's condition is stable. So how is that assessed?

That is, the plant's current growth rhythm is steady, and there are no pests or diseases on the flowers or leaves. At this time, changing the growing medium has the least impact on the plant. If you change the growing medium for those weak plants at the right time, you will surely be surprised to find that they will change a great deal. Plants that originally did not grow very well will seem to be injected with vitality all at once, growing especially fast, and may even suddenly surge and bloom with beautiful flowers.
