Does cutting the flower spike after a Phalaenopsis finishes blooming affect reblooming?
"The flowers on my Phalaenopsis at home have all faded - should I cut that flower spike or not?" This seemingly simple choice actually hides the secret of whether a Phalaenopsis can bloom beautifully again!
After blooming, the Phalaenopsis flower spike can be cut or left alone, but whether you cut it really does affect reblooming. The key is your plant's condition and how you want to grow it. - it's that stalk growing out from between the leaves and topped with flower buds. After the flowers fade it becomes an "empty stalk," but this stalk is not a useless "piece of scrap."

If your Phalaenopsis has especially strong roots and glossy green leaves with no yellowing or softening, then the flower spike can be left for now. That's because some Phalaenopsis have

If your Phalaenopsis has slightly yellowing leaves after blooming, roots that don't look so plump, or a flower spike that has already shriveled or turned black, then it's best to cut it off promptly. There's a trick to cutting too: don't cut flush with the base, just leave a3-5 cm stub - first, to avoid wound infection, and second, in case you later want a new shoot to emerge from the stub, there's still a chance. After cutting, it's best to apply a little carbendazim to the wound, let it dry, and then water as usual. The benefits of cutting the spike are obvious: it lets the plant concentrate nutrients on growing new roots and leaves, building up strength for the next bloom. Usually grown this way, the next rebloom is more punctual and the flowers are more abundant.

There are also pitfalls that beginners easily fall into, and I must especially remind you of them. For example, some people think"keeping the spike will always lead to more blooms," so they stubbornly keep it no matter how poor the plant's condition is, resulting in the Phalaenopsis being "worn out," with no new leaves growing and the roots gradually shrinking. Others cut too aggressively and cut all the way to the base, making too large a wound that is prone to infection by pathogens. In addition, whether or not you cut the spike, after blooming you must give the Phalaenopsis some nutrients - you can buy a special fertilizer for Phalaenopsis, dilute it, and water with it once every half month. Don't use strong fertilizer, or it will easily burn the roots.
Whether to cut the flower spike after Phalaenopsis blooms depends on the plant's condition, so you must"act according to the situation" and not apply a one-size-fits-all rule. As long as care is proper, whether or not you cut it, next time it will still bloom beautiful little butterflies for you!
