Phalaenopsis Winter Home Care Methods and Causes of Black Spots on Leaves

Many people are very fond of Phalaenopsis, yet caring for them stumps quite a few people, especially after winter arrives in December, when many flower lovers run into problems like black spots on the leaves, because the winter wind is biting cold, and every time the plant is blown by the cold wind it leaves scars behind. So in the cold winter, how should Phalaenopsis be cared for correctly? What can be done to reduce the damage caused to the leaves?

In fact, when caring for Phalaenopsis in winter, avoid spraying water on its leaves, because this action easily causes cold spots. The reason is that Phalaenopsis leaves are themselves delicate and sensitive, and especially when the winter temperature is relatively low, water droplets on the leaves freeze very easily. This process not only affects the Phalaenopsis's appearance, but also causes its leaves to wither and drop off.

So, how can this kind of cold spot be avoided? In winter it is best to move the plant back indoors for care, ensuring that the overall ambient temperature for the Phalaenopsis stays above 15 degrees, which can lower the risk of water droplets freezing. At the same time, humidity should also be increased; it is suggested to place some water basins or humidifiers around the plant, or use a humidifier to raise the surrounding air humidity, and after each humidifying the indoor ventilation should be maintained to avoid pathogen growth caused by excessive closeness. Remember here: absolutely do not spray water directly on the leaves.

In terms of care, besides not leaving water on the Phalaenopsis leaves, of course also do not put it outdoors in the wind when it is cold, as this can prevent cold spots from forming. At the same time, control the watering frequency to prevent root rot from overly wet potting soil; in winter follow the rule of watering when the soil is slightly dry, generally watering once about every 7 days. As for light, a moderate amount of light can be given during the warmer part of the day, and at night put a black plastic bag over the plant to protect against cold damage. Finally, regarding fertilizing, as winter temperatures drop the plant enters a semi-dormant state, so at this time absolutely do not fertilize again; wait quietly until the following spring before applying fertilizer. In short, in daily care look at the plant's condition more often, and promptly detect and deal with pests and diseases.
