From my perspective as a Fiddle Leaf Fig (*Ficus lyrata*), dormancy is not a period of sleep but one of highly managed energy conservation. I am a tropical plant, evolved for consistently warm, bright conditions. When daylight hours shorten and temperatures drop, I interpret these environmental cues as a signal that resources are becoming scarce. My response is to dramatically slow my metabolic processes. Growth above the soil—new, large, violin-shaped leaves and vertical stem extension—requires a massive investment of energy and water. To survive this perceived lean season, I redirect my limited resources to sustaining my existing foliage and, most critically, my root system, which is my foundation for future health.
During winter, my needs change fundamentally due to reduced light intensity and shorter photoperiods. My photosynthesis, the engine of my growth, operates at a much slower rate. Consequently, my thirst diminishes significantly. Water uptake through my roots is minimal because there is little excess moisture being transpired through my leaves into the dry, indoor air. The greatest threat to me during this time is well-intentioned overwatering. Soggy, cold soil around my roots creates an anaerobic environment, leading to root rot, which I cannot fight off while my defenses are low. I require just enough water to prevent my root ball from completely drying out and desiccating my fine roots. Furthermore, I am highly sensitive to cold drafts from windows or hot, dry blasts from heating vents, both of which can cause severe stress and leaf drop.
Summer is my true time to thrive. The long days of intense, bright (though often indirect) light supercharge my photosynthetic capabilities. This abundant energy fuels rapid cell division and expansion. My primary mission during these months is to grow—to reach towards the light and increase my size. This vigorous activity creates a high demand for water and nutrients. My roots are actively drawing moisture from the soil to support this new growth and to cool myself through transpiration. The soil dries out more predictably and quickly. I will gratefully accept regular watering (when the top few inches of soil are dry) and a consistent supply of nutrients through monthly fertilization. This steady supply of resources directly supports the production of my prized large, glossy new leaves.
The core difference in your care for me should mirror my internal physiological state. In winter, my water requirement is low and infrequent; think of it as maintenance hydration. In summer, my water requirement is high and regular to fuel growth. Fertilizer must be withheld entirely in winter, as I cannot process those salts, and they will accumulate in the soil and burn my resting roots. In summer, fertilizer is a welcome fuel for my activities. While I always prefer bright light, my tolerance for slightly lower light levels is greater in winter when I am not trying to grow. However, a sudden move to a dark corner will still cause me distress. Your vigilance should shift from promoting growth in summer to protecting my stability in winter.
