How to handle new roots on Phalaenopsis orchids? Growing them this way in hot weather makes them more likely to survive
In recent years, Phalaenopsis orchids have become an indispensable potted plant for the Lantern Festival, and their floral beauty is deeply loved by many flower enthusiasts. As a result, flower growers have followed the trend and bred a wide variety of orchid cultivars, from common ones to rare ones, each with its own merits. Some potted plants are large, with flowers that arch and droop after blooming, offering a distinctive charm, while some potted plants are small and exquisite, placed on an office desk, making anyone who looks at them feel delighted.

As Jingzhe arrives, the weather gradually heats up, and at this time home-grown Phalaenopsis orchids will slowly develop a few minor issues, such as the problem of new roots and aerial roots that many flower enthusiasts pay attention to. When the newly grown roots reach a certain length, a small black spot appears at the root tip, and then growth stops, and at this time there may also be signs of mold on some roots. In other cases, the crystal tips were originally pointed but now have become round and also no longer continue to grow. So when encountering the same situation, how should it be solved?

First, let's talk about the upcoming summer. In this season, whether in the south or the north, temperatures are high, and if the balcony ventilation is also poor and sphagnum moss is used to grow Phalaenopsis orchids, then the probability of problems will greatly increase. Therefore, 1 must pay attention to ventilation, and you can also keep a fan at home to blow a little air (a gentle breeze), which can improve things quite a bit.

Second, unclean sphagnum moss is also a big problem. Imported sphagnum moss is expensive now, and cheap goods may go bad after only 2 months of use, which leads many flower enthusiasts to reuse it, thinking that scalding it with boiling water solves the problem. In fact, to thoroughly eliminate bacteria, the only option is to replace it with healthy new sphagnum moss.

Another common one is the crystal tip turning into a small black spot. This situation means the medium at the root tip has become diseased, and it is also a distress signal from the plant, indicating that this place is not suitable for growth, so it pauses growth to preserve its life.

Finally, of course, it can also be caused by fertilizer concentration being too high. Whether using special orchid fertilizer or the most commonly bought Huaduoduo on the market, the dosage must be controlled at about 3 parts per thousand.

If the potting medium is bark-based, then it is recommended not to use liquid fertilizer, and instead choose something like Mofei or Osmocote. In short, fertilizer that is too concentrated is the key reason roots do not grow well, and also pay attention when using liquid fertilizer, as many flower enthusiasts do not mix it evenly, which is also a case of using concentrated fertilizer.
