Monstera Adansonii Care: A Complete Guide

Monstera adansonii won’t kill you. Seriously. Keep it in bright indirect light, water it roughly every 7 days, and stop fussing with it. Everything else is just noise. This guide covers the noise, in case you want to get weird with it.

Quick facts

Latin name	Monstera adansonii
Light	Bright indirect
Water	Roughly every 7 days. Smaller leaves dry out faster than deliciosa. Check soil weekly.
Humidity	60-80%
Temperature	18-27 °C
Soil	Chunky aroid mix
Fertilizer	Balanced liquid fertilizer monthly
Pet safe?	Toxic to cats and dogs (same as M. deliciosa)

Light

Bright indirect. Too dark and the plant slows down or stops pushing new growth. Too much direct sun and you get scorched leaves with bleached patches.

An easy test: hold your hand 30 cm above the plant at midday. A sharp shadow means bright light. A soft fuzzy shadow is medium. No shadow at all is too dim for most species.

Watering

Smaller leaves dry out faster than deliciosa. Check soil weekly.

Forget weekly schedules. Monstera adansonii in a warm bright spot in summer might need water every 3 to 11 days, and once every 3 weeks in winter. The finger test always beats the calendar.

Signs of overwatering: yellowing lower leaves, soft mushy base, fungus gnats. Signs of underwatering: drooping, curling, crispy edges. If you’re not sure, err on the dry side.

Humidity and temperature

Monstera adansonii likes 60-80% humidity. Most homes in winter sit closer to 25-35%, which is why crispy leaf tips are a common complaint. Group plants together to raise local humidity, or run a small humidifier in the corner. Misting is theatre. Don’t bother.

Keep room temperature between 18-27 °C and away from cold drafts, AC vents, and radiators.

Soil and repotting

Use chunky aroid mix. Drainage matters more than any specific brand. Repot every 1-2 years in spring, going up one pot size only. A pot that is too big traps water around the roots and kills the plant faster than any pest.

Fertilizing

Balanced liquid fertilizer monthly. Skip fertilizer in winter. Plants are dormant and excess nutrients sit in the soil and burn the roots.

Propagation

Stem cuttings with a node. Most cuttings root within 2-4 weeks in spring. Use a jar of room-temperature water and change it weekly to prevent rot.

Common problems

• Small leaves and long internodes (low light)
• Brown leaf tips (low humidity)

Pet safety

Bringing a new monstera adansonii home

The first two weeks are the hardest. Monstera adansonii adjusts to your home’s light, humidity, and watering pattern, and some leaf drop or stress is normal. Pick a spot and leave it. Resist the urge to move it around looking for the perfect light. Plants acclimate by sending out roots toward water and tilting growth toward light, and every move resets that adaptation. Water sparingly during this period because the root system is doing more reconnecting than absorbing. After two to three weeks, you can settle into a normal routine.

If you see small leaves and long internodes in the first week, do not panic. That is almost always shipping stress or acclimation, not a care problem. Watch for two more weeks before changing anything.

Seasonal care

Monstera adansonii grows on a yearly cycle that most beginners forget:

• Spring (March-May): Active growth restarts. Increase watering frequency, resume fertilizing, and consider repotting if the plant outgrew its container last year. New leaves should appear within 4-6 weeks of the days getting longer.
• Summer (June-August): Peak growing season. Watch for faster soil drying in hot weather. Aim for watering roughly every 3 days. Move away from windows during heatwaves to avoid scorching.
• Autumn (September-November): Growth slows. Cut fertilizer to half. Watering frequency drops as light decreases. This is when most overwatering happens because people keep summer schedules.
• Winter (December-February): Near-dormancy. Water roughly every 14 days. No fertilizer. Move away from cold windows and away from heating vents.

Where to put monstera adansonii in your home

The exact spot matters more than the species. Good candidate locations:

• 1-2 metres from a south or east-facing window (best for most species, monstera adansonii included).
• On a bookshelf at chest height near a window, with the plant facing inward (so trailing growth shows).
• A bathroom with a window if humidity is a priority and the plant is humidity-loving.

Bad candidate locations:

• Directly above a radiator or AC vent. The constant temperature swing scorches leaves and dries soil fast.
• A windowless hallway. Light is the single biggest factor in plant survival, and there is no substitute for some daylight.
• Right against window glass in winter. Cold conducts through glass and burns leaves overnight.

How to tell if your monstera adansonii is healthy

Three weekly checks take 90 seconds:

1. New growth. A healthy plant pushes a new leaf or shoot every 2-4 weeks in spring and summer. If it has not produced anything new in 8 weeks of warm weather, conditions are off.
2. Leaf colour and firmness. Healthy leaves are firm, the colour matches when you bought the plant, and they hold their shape. Soft, faded, or limp leaves are early warning.
3. Soil and roots. Stick a finger 3 cm into the soil. Damp but not soaked is correct most of the time. White roots gently visible through the drainage hole are a good sign. Brown mushy roots showing through the hole need immediate attention.

Choosing a healthy specimen at the nursery

What to inspect before buying monstera adansonii:

• Lift the pot. A plant that has been recently watered and is too light for its size has poor root development. Pass on it.
• Look under the leaves. Sticky residue, webbing, or small moving dots mean pests, and you are buying yourself a quarantine and treatment job.
• Check the soil surface for fungus gnats (tiny flying insects) and the rim of the pot for white crusty buildup (mineral salts, a sign of over-fertilizing).
• Avoid plants displayed under fluorescent overhead lighting in cool corners. They are usually already declining and will struggle to recover at home.

Pay 20-40% more at a specialty nursery if you can. The plants are healthier, the staff knows the species, and the survival rate is much higher than big-box stores.
