Can You Fertilize Phalaenopsis Orchids During Blooming? The Correct Way to Fertilize with Diluted Fertilizer

Phalaenopsis orchids have a unique flower posture, blooming like dancing butterflies. Placed anywhere in the home, they instantly become a focal point. Whether your decor style is modern minimalist or classic and elegant, they blend in perfectly, which is why they have become a must-buy flower for Chinese New Year over the past 5 or 6 years. However, this festive and upscale flower is not as easy to grow well as one might imagine, and many flower enthusiasts have run into various problems.

On the journey of caring for Phalaenopsis orchids, one flower enthusiast asked: can you fertilize as usual when the plant is in bloom? I bought a Phalaenopsis orchid not long ago during the Spring Festival, and it is blooming now. Yesterday I was pleasantly surprised to find that it had produced another flower spike. Although this is a happy thing, I am also a bit worried that the nutrients may not be enough. I cannot bear to pinch off this newly grown flower spike, so I am really torn. What should I do?

There is a saying in Phalaenopsis orchid care that it is best not to fertilize when the plant is in bloom, so that the flowers can last longer. But in fact, because I grow all kinds of flowers at home, different varieties do not bloom at fixed times, and I use a water pump to fertilize, spraying fertilizer over a large group of flowers all at once. There is no way to avoid only the blooming Phalaenopsis orchids, so in practice they do get sprayed with fertilizer during their blooming period. That said, in reality, doing so does not have any obvious negative effect on Phalaenopsis orchids.

However, one thing to note is that when fertilizing, you must be very careful and keep the concentration as low as possible, diluting it to about 10000 to 20000 times, just to provide the plant with some basic nutrients needed for growth. Through my long-term practical observation, the flowers still bloom just fine, the blooming period has not been seen to shorten, and the plant also looks very healthy.

So, I think you can also follow my method and not deliberately avoid fertilizing during the blooming period. As long as the fertilizer is diluted properly and you apply light fertilizer frequently, the effect on Phalaenopsis orchids will not be significant. Especially for the orchid you mentioned that has produced a new flower spike, if you are worried that the nutrients will not be enough, just apply light fertilizer to it.
