How to Care for Monstera Deliciosa Indoors

Monstera Deliciosa — the Swiss Cheese Plant — is one of the most recognisable houseplants in the world. With its dramatic fenestrated leaves and easy-going nature, it's become a staple in homes and cafes alike. But "easy" doesn't mean "indestructible." Here's everything you need to know to keep yours thriving.

Light Requirements

Monstera thrives in bright, indirect light. A spot 1–3 metres from a south or east-facing window is ideal. Direct afternoon sun will scorch the leaves; too little light and the plant stops producing its signature splits.

If your space lacks natural light, a full-spectrum grow light on a 12-hour timer works well. Signs your Monstera needs more light: small leaves with no fenestration, slow growth, and stems reaching toward the window.

Watering Schedule

Water when the top 5 cm of soil are dry — typically every 7–10 days in summer and every 14–21 days in winter. Stick your finger into the soil; if it's still moist, wait.

Common watering mistakes:

• Watering on a fixed schedule regardless of soil moisture
• Letting the plant sit in water (causes root rot fast)
• Using cold tap water — let it stand overnight or use filtered water at room temperature

Humidity and Temperature

Monstera originates from the tropical forests of Central America. It prefers:

• Humidity: 60–80% (though it tolerates household humidity down to 40%)
• Temperature: 18–27°C (64–80°F)
• Avoid cold drafts, air conditioning vents, and temperatures below 10°C

To raise humidity: group plants together, place a tray of pebbles and water beneath the pot, or use a humidifier nearby.

Soil and Potting

Use a well-draining aroid mix: combine standard potting soil with perlite (30%) and orchid bark (20%). Good drainage is non-negotiable — waterlogged roots are the number one killer.

Repot every 1–2 years in spring when roots circle the pot or start pushing through the drainage holes. Go up one pot size only; oversized pots hold too much moisture.

Fertilising

Feed monthly during the growing season (spring and summer) with a balanced liquid fertiliser (20-20-20 NPK) diluted to half strength. Stop fertilising in autumn and winter when growth slows.

Common Problems

Yellow leaves: Usually overwatering. Let the soil dry out completely, check for root rot, and adjust your watering cadence.

Brown leaf tips: Low humidity or fluoride in tap water. Switch to filtered water and increase humidity.

No fenestration (holes): Insufficient light or the plant is too young. Monsteras typically develop splits after producing 5–6 leaves.

Leggy growth: Not enough light. Move closer to a window or add a grow light.

Pests: Mealybugs and spider mites love Monstera. Check the undersides of leaves weekly; treat with neem oil solution or insecticidal soap at the first sign.

Propagation

Monstera is one of the easiest plants to propagate. Take a stem cutting with at least one node (the brown bump the root grows from) and one leaf. Place in water or moist sphagnum moss and keep in a warm, bright spot. Roots typically appear in 3–6 weeks.

Quick Reference

Factor	Ideal
Light	Bright indirect, 1–3m from window
Water	Every 7–14 days, let top 5cm dry
Humidity	60–80%
Temperature	18–27°C
Fertiliser	Monthly, spring–summer
Repot	Every 1–2 years in spring

Monstera is forgiving enough for beginners but rewarding enough for experienced plant parents. With the right light and a consistent (not excessive) watering routine, yours will produce those iconic split leaves season after season.
