Why Phalaenopsis Orchid Flower Stalks Grow Slowly and How to Clean Dust Off the Leaves
If you were to pick out one flower with truly outstanding elegance, the Phalaenopsis orchid would certainly earn a place, looking like a work of art when placed at home, which is why its sales have ranked among the top this year. However, as more people buy them, everyone has encountered their own different problems in caring for them.
On the journey of caring for Phalaenopsis orchids, you will always run into questions that books cannot answer. This flower enthusiast said that she had just started growing Phalaenopsis orchids, having bought one during last year's Spring Festival, and to her surprise it bloomed several times this summer; but now, although it has sent up another flower bud, the flower stalk has started growing very slowly, growing only 2 cm in about a month. Is this situation normal?
Also, I am in Wuhan, and my home has radiator heating installed. As soon as the weather turned cold, I quickly moved the Phalaenopsis orchid indoors, and I water it about once a week. I always feel that my method of caring for it is not quite right, but I cannot put my finger on what the problem is. Could you help me take a look and tell me what I should do to make this flower bud grow quickly and bloom smoothly?
After reading your question, the editor cannot help but give your methods a thumbs-up. Being able to master the tricks of growing in sphagnum moss and controlling water so well, your Phalaenopsis orchid is in pretty good condition. Judging from your situation, the plant is not only growing new roots now but has also sent up a new flower stalk; the only issue is that the flower stalk is growing slowly.
In fact, how fast or slow the flower stalk grows depends on temperature. If the overall temperature is too cold, the flower stalk will indeed grow slowly, but it cannot be ruled out that the flower stalk lacks stamina for growth, making it grow somewhat weakly. Let me offer you a few tips. First, dust and water stains on the leaves should be wiped clean, so the leaves can breathe better. Then, the lighting also needs to be improved. In your location, if indoors, you can let it get sun through the glass; this way you can ensure lighting without sunburn.
Finally, there is one more thing to remind you of, which many flower enthusiasts overlook: when growing Phalaenopsis orchids into the second year, it is recommended to change the potting medium, because after a year of growth, the medium has already somewhat decomposed. If you want this Phalaenopsis orchid to grow more robustly and bloom more, after the flowers fade next year, be sure to cut off the bad branches and replace the medium with new material.
