For flower lovers who are new to the gardening circle, Phalaenopsis is an ideal choice, because it doesn't need to be watered frequently, nor does it require strong light. It can thrive with just moderate humidity and ventilation. Many flower lovers say that although Phalaenopsis has a low maintenance cost, there are still some problems in the process of maintenance that they can't figure out.
In terms of maintenance, many flower lovers encounter various strange problems. Among them, some flower lovers mentioned, "There are black spots on the newly grown leaves of my Phalaenopsis. I'm completely confused and don't know what's going on. At present, I use sphagnum moss as the soil medium for maintenance, but I've always been struggling with the state of the sphagnum moss. Is it more beneficial to the growth of Phalaenopsis if I press the sphagnum moss tightly, or is it better to keep it loose?"
Based on the symptoms of your Phalaenopsis, I guess it's most likely infected with a disease. You must be more careful in this kind of situation. It is recommended that you carefully twist off the entire leaf with black spots as soon as possible, and then isolate this Phalaenopsis for a period of time for separate maintenance. The purpose of doing this is to prevent the diseased leaves from spreading further and affecting other healthy plants.
At the same time, whenever the leaves turn black, most of the reasons are excessive moisture and poor ventilation. You should change its placement position and try to put it in a ventilated place. Also, check if it's caused by too frequent watering, because only in this way can the recurrence of diseases be reduced at the root.
When it comes to the problem of sphagnum moss maintenance, in fact, both the methods of pressing the sphagnum moss tightly and keeping it loose have been tried by people, and Phalaenopsis can grow healthily with both methods. However, in comparison, it is more difficult to use loose sphagnum moss for maintenance, because loose sphagnum moss has extremely high requirements for the control of moisture and nutrients.
For most flower lovers, it is still recommended to press the sphagnum moss more tightly, which will be more convenient for controlling the amount of watering. Under various environmental conditions, the compact sphagnum moss can relatively stably maintain the humidity required for the growth of the plant, which is more conducive to the healthy growth of Phalaenopsis.
