The link between available light and watering need

The delicate balance between light exposure and watering requirements in plants, Monstera included, is intricately tied to the processes of photosynthesis and transpiration.

Photosynthesis and Its Winter Slowdown:

In the realm of Monstera care, light plays a pivotal role in photosynthesis. This process transforms carbon dioxide and water into glucose and oxygen, fueling the plant's growth. However, during winter, with shorter days and less intense sunlight, the overall photosynthetic activity of the Monstera tends to decrease.

Transpiration's Connection to Light Levels:

Parallel to photosynthesis, transpiration is the plant's process of taking up water through its roots and releasing it into the atmosphere through tiny leaf pores, known as stomata. As light diminishes, the rate of photosynthesis drops, affecting the plant's water uptake and transpiration rates.

Effects on Watering Needs:

Reduced Water Uptake: The winter slowdown impacts the metabolic processes of the Monstera, leading to a decrease in water uptake from the soil.

Decreased Transpiration: In response to lower light levels, the Monstera's stomata tend to close to minimize water loss, contributing to an overall decrease in transpiration and, consequently, reduced water requirements.

Tips for Adjusting Watering:

  1. Monitor Soil Moisture: With subdued light and decreased plant activity, adjust your watering frequency. Regularly check soil moisture, and water when the top layer feels dry to prevent overwatering during the winter months.
  2. Avoid Waterlogged Soil: Lower light levels mean the plant is utilizing water at a slower pace. To prevent root rot, especially in cooler temperatures, ensure your Monstera is potted in well-draining soil with container drainage holes to avoid water accumulation.
