How Much Light Does a Monstera Need?

Monsteras thrive in bright, indirect light. They naturally grow in tropical rainforests under the canopy, where they receive filtered sunlight. Direct sunlight can scorch their leaves, while insufficient light can stunt growth and lead to fewer fenestrations.

Optimal Light: Bright, indirect light for 8–12 hours per day.
Low Light Tolerance: Monsteras can survive in low-light conditions but may grow slower and develop smaller, less fenestrated leaves.

Best Lighting Conditions for Monstera

1. Bright, Indirect Light

Place your Monstera near an east- or south-facing window with sheer curtains to filter the sunlight.
Keep it 3–5 feet away from a west-facing window to avoid the harsh afternoon sun.

2. Artificial Light

If natural light is insufficient, use grow lights to provide the necessary brightness.
Choose full-spectrum LED grow lights for optimal results, keeping the light 12–18 inches away from the plant.

3. Avoid Direct Sunlight

Prolonged exposure to direct sunlight can cause leaf burn, characterized by brown, crispy edges.

Signs Your Monstera Is Getting the Wrong Light

Too Little Light

Small Leaves: New leaves may grow smaller and lack fenestrations.
Leggy Growth: The plant stretches towards the light, creating long, sparse stems.
Yellowing Leaves: A lack of light can cause leaves to turn yellow.

Too Much Light

Leaf Burn: Brown, crispy patches on the leaves are a sign of excessive direct sunlight.
Fading Colors: Overexposure can bleach the leaves, causing them to lose their vibrant green hue.

How to Adjust Light for Your Monstera

Move Closer to a Window: If your Monstera isn’t receiving enough light, move it closer to a bright, indirect light source.
Add a Sheer Curtain: For plants in direct sunlight, use a sheer curtain to filter the light.
Use Grow Lights: Supplement natural light with artificial lighting in darker spaces.
Rotate the Plant: Rotate your Monstera weekly to ensure even light exposure and balanced growth.

Tips for Maintaining Ideal Lighting for Monstera

Monitor Light Levels: Use a light meter to ensure your Monstera receives 200–400 foot-candles of light.
Clean the Leaves: Dusty leaves can block light absorption, so wipe them regularly with a damp cloth.
Combine Natural and Artificial Light: Use grow lights in addition to natural light in darker rooms.
Avoid Frequent Relocation: Keep your Monstera in a stable light environment to prevent stress.
