Care

Light

Monstera deliciosa thrives in bright, indirect light, which helps promote large leaves with fenestrations. While it can adapt to lower light conditions, this may result in slower growth and fewer splits. Direct sunlight should be avoided, as it can scorch the leaves. Ideally, place it near a window with filtered light or use sheer curtains to diffuse sunlight.

Watering

Water when the top 2-3 inches of soil feel dry. Adjust watering frequency based on seasonal changes—more frequently during the growing season (spring and summer) and less during fall and winter. Overwatering is a common issue, so always check the soil before watering. Use a pot with drainage holes and empty the saucer to prevent water buildup.

Humidity & Temperature

Monsteras thrive in moderate to high humidity and temperatures between 65-85°F (18-29°C). While they can tolerate average household humidity, higher levels help prevent browning leaf tips. Increase humidity by misting the plant, using a humidifier, or placing it on a pebble tray. Avoid placing the plant near drafts, radiators, or air conditioners.

Soil

Use a well-draining, aerated soil mix to prevent compaction and allow for proper drainage. A mix of potting soil, orchid bark, perlite, and peat moss works well. This combination retains moisture while keeping the roots oxygenated and healthy.

Fertilization

Feed with a balanced, water-soluble fertilizer, diluted to half strength, every 4-6 weeks during the active growing season (spring and summer). Reduce or stop fertilization in fall and winter when growth naturally slows. Be cautious of over-fertilizing, as it can cause salt buildup and leaf damage.

Maintenance

Pruning

Regularly remove yellow, dead, or damaged leaves to maintain plant health and improve its appearance. Prune leggy stems to encourage bushier growth and redirect the plant’s energy. Use sharp, sterilized pruning shears to minimize the risk of infection. Pruning also helps control the plant’s size and shape.

Repotting

Repot every 1-2 years or when roots begin to outgrow the pot. Check the roots annually—if they are circling the bottom or emerging from drainage holes, it’s time to repot. Choose a container 1-2 inches larger in diameter and refresh the soil with a well-draining mix. Spring is the best time to repot, as the plant is actively growing.

Support

Monstera deliciosa is a natural climber and benefits from a moss pole, trellis, or stake to support its aerial roots. Secure the stems with plant ties to encourage vertical growth and the development of larger, more fenestrated leaves. Keeping the support structure moist helps the aerial roots attach more readily.

Propagation

Monsteras propagate easily through stem cuttings:

1. Select a cutting – Choose a healthy stem with at least one node and, if possible, an aerial root.
2. Make a clean cut – Use sterilized pruning shears or scissors to cut below a node.
3. Root in water or soil – For water propagation, place the cutting in a jar of water and change the water weekly. For soil propagation, plant the cutting in moist, well-draining soil.
4. Transplant – Once roots are 2-4 inches long (typically in 2-4 weeks), transfer the cutting to a pot with a well-draining soil mix.

Air Layering

Air layering is another effective method of propagating Monstera deliciosa, particularly for larger plants:

1. Select a healthy stem – Identify a section of the stem with a node and, if possible, an aerial root.
2. Make an incision – Use a clean knife to carefully make a small, upward cut about halfway through the stem just below the node.
3. Wrap with moist sphagnum moss – Pack damp sphagnum moss around the incision and cover it with plastic wrap. Secure it with string or twist ties to hold the moss in place.
4. Maintain moisture – Check the moss regularly to ensure it stays moist. If needed, carefully unwrap and mist the moss before re-securing it.
5. Wait for roots to develop – Roots typically form within 4-6 weeks. Once you see healthy roots through the moss, cut below the rooted section.
6. Transplant – Remove the plastic wrap and moss, then plant the rooted cutting in a pot with a well-draining soil mix.

Common Issues

Yellow Leaves

Cause: Overwatering, underwatering, or nutrient deficiencies.

• Solution: Check the soil moisture and adjust watering accordingly. Ensure the pot has drainage holes to prevent waterlogging. If the issue persists, apply a balanced liquid fertilizer every 4-6 weeks during the growing season.

Brown Leaf Edges or Tips

Cause: Low humidity, underwatering, or excess fertilizer.

• Solution: Increase humidity by misting the plant or using a humidifier. Ensure consistent watering and flush the soil if you suspect fertilizer buildup.

Drooping Leaves

Cause: Underwatering, overwatering, or temperature stress.

• Solution: Check soil moisture and water accordingly. If the plant is overwatered, allow the soil to dry out partially before watering again. Maintain consistent room temperatures between 65-85°F.

Lack of Fenestrations (Holes in Leaves)

Cause: Insufficient light, young age, or poor nutrition.

• Solution: Move the plant to a brighter location with indirect light. Fenestrations develop as the plant matures, so patience may be required for younger plants. Ensure regular feeding during the growing season.

Pests (Spider Mites, Mealybugs, Scale)

Symptoms: Discolored or damaged leaves, webbing, or sticky residue.

• Solution: Wipe leaves with a damp cloth and apply insecticidal soap or neem oil weekly until the infestation clears. Isolate affected plants to prevent spreading.

Root Rot

Cause: Overwatering, poor drainage, or compacted soil.

• Solution: Remove the plant from the pot, trim off affected roots, and repot in fresh, well-draining soil. Ensure the pot has drainage holes and avoid overwatering.

Stunted Growth

Cause: Poor lighting, nutrient deficiencies, or root-bound conditions.

• Solution: Move the plant to a location with adequate indirect light. Check for root crowding and repot if necessary. Apply a balanced fertilizer during the growing season.

By following these care guidelines, your Monstera deliciosa will reward you with lush, fenestrated leaves, creating a beautiful, tropical ambiance in your space.
