Monstera plants (Monstera deliciosa) naturally grow in tropical rainforests, where they receive dappled sunlight through the canopy. If your Monstera is producing small leaves, it may not be getting enough light. Plants rely on light for photosynthesis, which fuels growth. Without adequate light, the plant conserves energy by producing smaller leaves. Place your Monstera near a bright, indirect light source (e.g., an east- or north-facing window) to encourage larger leaf development.
Monstera leaves start small and increase in size as the plant matures. Juvenile Monsteras often produce smaller, heart-shaped leaves without fenestrations (holes). As the plant ages and develops a stronger root system and taller stems, the leaves grow larger and develop their characteristic splits. Patience is key—ensure proper care, and the plant will eventually produce bigger leaves.
Plants require essential nutrients like nitrogen, phosphorus, and potassium for healthy growth. A lack of nutrients, especially nitrogen, can stunt leaf development. Monsteras are heavy feeders and benefit from regular fertilization during the growing season (spring and summer). Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks to promote larger, healthier leaves.
Monsteras grow vigorously and can quickly outgrow their pots. When roots become cramped (root-bound), the plant struggles to absorb water and nutrients efficiently, leading to smaller leaves. Check the roots—if they’re circling the pot or poking out of drainage holes, repot the plant into a container 2–3 inches larger in diameter with fresh, well-draining soil.
Both overwatering and underwatering stress the plant, affecting leaf size. Overwatering can cause root rot, limiting nutrient uptake, while underwatering dehydrates the plant, hindering growth. Monsteras prefer consistently moist but not soggy soil. Water when the top 1–2 inches of soil feel dry, and ensure the pot has drainage holes to prevent waterlogging.
Native to humid rainforests, Monsteras thrive in high humidity (60% or higher). Dry air can cause the plant to produce smaller leaves or develop brown edges. Increase humidity by misting the leaves regularly, using a pebble tray, or placing a humidifier nearby. Grouping plants together also helps create a more humid microclimate.
Monsteras are natural climbers, using aerial roots to attach to trees in the wild. Without support, the plant may focus energy on stabilizing itself rather than growing large leaves. Provide a moss pole, trellis, or stake to encourage vertical growth. As the plant climbs, the leaves typically increase in size and develop more fenestrations.
Monsteras prefer temperatures between 65–85°F (18–29°C). Exposure to cold drafts or sudden temperature fluctuations can slow growth and reduce leaf size. Keep the plant away from air conditioners, heaters, or drafty windows to maintain a stable environment.
Pests like spider mites, thrips, or scale insects can weaken the plant by sucking sap from the leaves, leading to stunted growth. Inspect the leaves regularly, especially the undersides, and treat infestations promptly with insecticidal soap or neem oil.
Some Monstera varieties naturally produce smaller leaves (e.g., Monstera adansonii compared to Monstera deliciosa). If you’re unsure of your plant’s species or cultivar, research its typical growth habits to set realistic expectations for leaf size.
