In its initial juvenile stage, a newly propagated or young Monstera deliciosa plant focuses its energy below the soil. This phase is characterized by the development of a robust root system rather than dramatic upward growth or leaf fenestration. You can expect a new plant to spend several months establishing itself. During this time, it may produce a few new leaves, but they will likely be small, heart-shaped, and solid—lacking the iconic splits and holes. The growth rate is relatively slow, often with a new leaf emerging every month or two, depending on conditions. Patience is key, as this foundational work is critical for supporting the spectacular growth to come.
Once a Monstera plant matures beyond its juvenile stage and is provided with a support structure like a moss pole or trellis, its growth rate significantly accelerates. This is because, in their natural habitat, Monsteras are hemiepiphytes that climb trees to reach the brighter sunlight of the forest canopy. When given a structure to climb, the plant will produce larger leaves at a faster pace. You can typically expect a well-established, supported Monstera to generate a new leaf every 4-6 weeks during its active growing season (spring and summer). Each new leaf will often be larger than the last, and the development of fenestrations (splits and holes) will become more pronounced.
The actual speed of growth is highly dependent on the care provided, which mimics its preferred tropical conditions. The four most critical factors are light, water, nutrients, and humidity. Bright, indirect light is the single greatest contributor to vigorous growth; insufficient light will result in slow growth and a lack of fenestrations. Consistent watering (allowing the top few inches of soil to dry out between waterings) prevents stress that can halt growth. Regular feeding with a balanced fertilizer during the growing season provides essential nutrients for producing new stems and leaves. Finally, higher humidity levels (above 50%) are preferred and help the plant operate efficiently, leading to steadier growth.
A Monstera's growth is not constant throughout the year. Its most rapid growth occurs during the longer, warmer days of spring and summer. This is when you will observe the frequent emergence of new leaves and aerial roots. Conversely, growth slows considerably during the shorter, cooler days of fall and winter. This is a period of dormancy where the plant's metabolic processes slow down. It is crucial to reduce watering and cease fertilization during this time, as the plant will not be actively using resources. It is normal for no new growth to appear for months during this dormant period before resuming again the following spring.
