Swiss cheese plants in low light: the ultimate guide to light exposure

The Swiss cheese plant, also known as Monstera deliciosa, is a popular indoor plant prized for its unique, perforated leaves. While it’s often assumed that these plants require ample sunlight, many plant enthusiasts wonder: can Swiss cheese plant grow in low light?

Understanding Light Requirements

To determine whether Swiss cheese plants can tolerate low light, it’s crucial to understand their light requirements. These plants are native to tropical rainforests, where they thrive in dappled shade under the canopy of larger trees. This suggests that they have adapted to grow in conditions with varying levels of light.

Adaptability to Low Light

While Swiss cheese plants prefer bright, indirect light, they can surprisingly tolerate low light conditions. However, it’s important to note that their growth and appearance may be affected.

Growth Rate

In low light, Swiss cheese plants may experience slower growth compared to their counterparts in brighter environments. The production of new leaves may be reduced, and existing leaves may grow smaller or less perforated.

Leaf Color and Size

Low light can also affect the leaf color and size of Swiss cheese plants. Leaves may become darker green and lose their vibrant variegation. Additionally, the leaves may remain smaller and fail to develop the characteristic holes or perforations.

Plant Health

Prolonged exposure to extremely low light can weaken Swiss cheese plants and make them more susceptible to pests and diseases. The plant may become leggy, with thin stems and sparse foliage.

Ideal Light Conditions

For optimal growth and appearance, Swiss cheese plants prefer bright, indirect light. Place them near an east- or west-facing window where they can receive several hours of sunlight each day. Avoid direct sunlight, as this can scorch the leaves.

Tips for Growing in Low Light

If you must grow Swiss cheese plants in low light, here are some tips to optimize their growth:

Choose the Right Variety

Some varieties of Swiss cheese plants are more tolerant of low light than others. Monstera deliciosa var. ‘Borsigiana’ and Monstera adansonii are known for their ability to tolerate lower light levels.

Provide Supplemental Light

If natural light is insufficient, consider using artificial grow lights to supplement the light available to the plant. Choose LED grow lights that emit a full spectrum of light.

Rotate the Plant

To ensure even growth, rotate the plant regularly so that all sides receive equal amounts of light. This will prevent the plant from becoming lopsided.

Prune Regularly

Pruning can help maintain the plant’s health and shape in low light conditions. Remove any yellowing or damaged leaves, and trim back any leggy stems to encourage new growth.

Fertilize Sparingly

Over-fertilizing can weaken Swiss cheese plants in low light. Fertilize only once a month during the growing season with a balanced liquid fertilizer diluted to half strength.

Wrap-Up: Embracing the Shadow

While Swiss cheese plants prefer bright, indirect light, they can surprisingly tolerate low light conditions with some adaptations. By choosing the right variety, providing supplemental light, and following proper care tips, you can successfully grow and enjoy these unique plants even in low-light environments.

What You Need to Know

Q: Can Swiss cheese plants survive in complete darkness?
A: No, Swiss cheese plants require some light to survive. However, they can tolerate very low light levels.

Q: How often should I water a Swiss cheese plant in low light?
A: Water the plant sparingly in low light, allowing the soil to dry out completely between waterings.

Q: Why are the leaves on my Swiss cheese plant turning yellow in low light?
A: Yellowing leaves in low light can indicate overwatering or nutrient deficiency. Reduce watering frequency and consider fertilizing the plant with a balanced fertilizer.
