Care

Everything it needs

9 essentials at a glance

Watering

Monstera acuminata prefers to be watered when the top inch of soil feels dry.

In general, water every 1-2 weeks, allowing excess water to drain. During the growing season (spring and summer), increase frequency if the plant is in a warm environment, while in fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf curling and browning edges.

Light

This plant thrives in bright, indirect light but can tolerate lower light conditions.

Ideally, place it near a window with filtered sunlight for 6-8 hours a day. Avoid direct sunlight, which can scorch the leaves, and note that too little light can slow growth and reduce leaf size.

Soil

Monstera acuminata prefers a well-draining potting mix, ideally a blend of peat, perlite, and orchid bark.

The ideal pH range is between 5.5 and 7.0. Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Humidity

This plant enjoys high humidity levels, ideally between 60-80%.

To increase humidity, consider using a humidifier or placing a tray of water with pebbles beneath the pot. Signs of low humidity stress include browning leaf tips and edges, while excessive humidity can lead to mold growth.

Temperature

Monstera acuminata thrives in temperatures between 65-85°F (18-29°C).

It is suitable for USDA hardiness zones 10-12. Protect it from temperatures below 50°F (10°C) as it can suffer from cold damage, and avoid placing it near drafts or heating vents.

Fertilizing

Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or similar during the growing season, applying every 4-6 weeks.

In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and stunted growth.

Pruning

Prune Monstera acuminata in spring to maintain its shape and remove any dead or damaged leaves.

Use clean, sharp scissors or pruning shears. You can also pinch back stems to encourage bushier growth. Deadheading is not necessary for this plant.

Repotting

Repot every 1-2 years or when the plant becomes root-bound, indicated by roots growing out of the drainage holes.

Choose a pot that is 1-2 inches larger in diameter. To repot, gently remove the plant from its current pot, loosen any tightly bound roots, and place it in fresh potting mix.

Propagation

Propagation can be done through stem cuttings or division.

For stem cuttings, take a cutting with at least one node and place it in water or moist soil. Change the water every few days if using water propagation. Best timing is during the growing season (spring or summer) for optimal growth.

Troubleshoot

When it's unhappy

Yellow leaves

Why it happens

Over-watering or insufficient light can lead to yellowing leaves.

How to fix it

Adjust watering frequency and ensure the plant receives adequate light.

Browning leaf tips

Why it happens

Low humidity or under-watering can cause leaf tips to brown.

How to fix it

Increase humidity levels and ensure consistent watering.

Root rot

Why it happens

Excess moisture in the soil can lead to root rot.

How to fix it

Allow the soil to dry out between waterings and ensure proper drainage.

Pests (e.g., spider mites, mealybugs)

Why it happens

Pests can infest the plant, especially in dry conditions.

How to fix it

Regularly inspect the plant and treat infestations with insecticidal soap or neem oil.

Stunted growth

Why it happens

Nutrient deficiency or inadequate light can hinder growth.

How to fix it

Fertilize regularly during the growing season and ensure the plant receives sufficient light.

Seasonal

Care through the year

Spring

In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth.

Summer

During summer, ensure the plant receives adequate light and humidity. Water more frequently as the heat increases.

Fall

In fall, gradually reduce watering as the plant's growth slows. Continue to fertilize until late fall.

Winter

In winter, water less frequently, allowing the soil to dry out more between waterings. Reduce fertilizing to once every 2-3 months.

Toxicity & Safety

Monstera acuminata is toxic to pets, particularly cats and dogs, as well as children. The leaves contain calcium oxalate crystals, which can cause oral irritation, swelling, and difficulty swallowing if ingested.
