From my perspective as an Orchid Cactus (Epiphyllum), dormancy is not a sickness or a period of death; it is a vital, deep rest. I am a tropical epiphyte, naturally growing on trees in jungles where winter brings cooler temperatures and significantly less rainfall. My growth cycle is dictated by these seasonal changes. The shortening daylight hours and dropping temperatures of autumn signal to my internal systems that it is time to slow down. I am not lazy; I am conserving every ounce of my energy. This period of rest is absolutely crucial for me to gather the strength required to produce my spectacular blooms in the coming spring and summer. Without this proper rest, I will likely become exhausted, leading to weak growth and few, if any, flowers.
To support my natural cycle, you must replicate the conditions of my native habitat. The most critical factor is temperature. I need to be placed in a much cooler location, ideally between 45-55°F (7-13°C). This chill is the key signal that tells my metabolic processes to dramatically slow down. It is not a harsh cold that will damage my cells, but a gentle, consistent coolness. Along with the cool temperatures, I require a significant reduction in water. My soil should be allowed to dry out almost completely between waterings. In the deepest part of winter, this might mean you only need to give me a very small drink once a month, just enough to prevent my succulent stems from shriveling excessively. Overwatering me now is a grave mistake—my roots are not actively drinking and will quickly rot in cold, wet soil.
While I am dormant, my needs for light and food change drastically. I still appreciate bright, indirect light. A spot near a cool windowsill is perfect, as it provides adequate light without the intense heat of summer. However, direct, hot sun is not necessary or beneficial. Most importantly, you must completely cease any fertilization. My system is shut down and I cannot process any nutrients. Feeding me during this time would be like offering a three-course meal to someone in a deep sleep—it would not be used, and the salts would simply build up in my soil, potentially chemically burning my delicate, resting roots and causing significant stress.
Please do not be alarmed by my appearance during this time. I will not look my best, and that is perfectly normal. You will notice that my growth has completely halted. My vibrant green stems may take on a slightly reddish or purple tint, and they may appear a little limp or wrinkled. This is a standard reaction to the cooler temperatures and reduced water, and it is not a sign of distress. I am simply hibernating. My job is to rest, and your job is to provide the stable, cool, and dry conditions that allow me to do so safely. Resist the urge to "help" me by watering more or moving me to a warmer spot; this will only interrupt my vital cycle and weaken me.
