Monstera Adansonii Wide Form (Wide form adansonii) care

Light

Bright but filtered. Monstera Adansonii Wide Form burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Thrives in bright, indirect light, which drives larger leaves and more fenestration. It tolerates medium light with slower growth and fewer holes. Keep out of direct sun, which bleaches and scorches the glossy leaves. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering monstera adansonii wide form: when the top 2-3 cm of soil is dry, roughly every 7-10 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Water thoroughly, then let the top few centimetres dry before watering again. It likes evenly moist but never soggy soil during growth; reduce watering in winter. Yellow leaves usually mean too much water.

Soil and pot

Monstera Adansonii Wide Form grows best in chunky, well-draining aroid mix. Use a rich aroid blend of potting soil, orchid bark, perlite and coir for moisture retention with sharp drainage. The climbing roots need aeration; a pot with drainage holes is essential. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Monstera Adansonii Wide Form sits happiest at around 50-70% humidity and 18-29°C (65-85°F). Prefers moderate to high humidity for the lushest, most fenestrated growth. It manages average home humidity but performs best above 50%; a humidifier or grouping plants helps significantly. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed monstera adansonii wide form sparingly. Feed every 2-4 weeks in spring and summer with a balanced liquid fertiliser at half to full strength; this is a hungry, fast climber. Reduce in autumn and stop in winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on monstera adansonii wide form in the Growli community. Each is annotated with the most common cause so you know where to start.

• Few or no fenestrations — Young plants and those in low light produce solid leaves; give bright indirect light and a pole to climb to encourage holes.
• Yellowing leaves — Usually overwatering or poor drainage; let the soil dry more and confirm the pot drains well.
• Brown, crispy leaf edges — Low humidity or underwatering; raise humidity and keep moisture even.
• Leggy growth — Long gaps between leaves indicate too little light; brighten the spot and provide a moss pole.

Propagation

Propagate from stem cuttings with at least one node and ideally an aerial root; root in water, sphagnum or moist soil. Rooting is fast and reliable, usually 2-4 weeks. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Monstera Adansonii Wide Form is toxic to pets. ASPCA lists Monstera (under Swiss cheese plant / Cutleaf philodendron) as toxic to cats and dogs. It contains insoluble calcium oxalate crystals that cause oral irritation, intense burning of the lips, mouth and tongue, excessive drooling, vomiting and difficulty swallowing if chewed. Keep away from pets. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
