Anthurium andraeanum 'Midori' (Midori anthurium) care

Light

In the wild anthurium andraeanum 'midori' grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Bright, indirect light keeps the green spathes vivid and encourages repeat flowering. Direct sun fades and scorches the bracts, while low light produces sparse blooms and stretched, weak stems. An east-facing window is ideal. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Aim for when the top 2-3 cm of mix is dry, roughly every 5-7 days in growth for anthurium andraeanum 'midori', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water deeply and let excess drain away; allow the surface to dry before watering again. The fleshy roots are rot-prone, so never leave the pot in standing water. Reduce frequency in the cooler, lower-light months.

Soil and pot

Anthurium andraeanum 'Midori' grows best in chunky, free-draining epiphytic aroid mix. Use orchid bark, perlite, and coco coir with a handful of charcoal. The open, airy structure mirrors its epiphytic roots in nature, holding light moisture while letting water and air move freely through the root zone. 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

Anthurium andraeanum 'Midori' sits happiest at around 50-70% humidity and 18-29°C (65-84°F). Happiest above 50% humidity, where foliage stays unblemished and blooms last longer. In dry rooms leaf and spathe edges brown. A pebble tray, humidifier, or grouping with other plants helps; avoid misting directly onto open spathes. 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 anthurium andraeanum 'midori' sparingly. Apply a balanced houseplant fertiliser at half strength every 4-6 weeks during spring and summer, or a bloom-boosting high-phosphorus feed to keep spathes coming. Cut back in autumn and winter. Periodically flush the mix to prevent salt accumulation that burns root tips. 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 anthurium andraeanum 'midori' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Spathes turning brown or dull — Low humidity, draughts, or hard-water salts. Raise humidity, keep away from heat sources, and water with filtered or rainwater.
• Few flowers — Most often too little light or excess nitrogen feed. Brighten the spot and switch to a higher-phosphorus bloom fertiliser in the growing season.
• Yellowing leaves — Typically overwatering or a dense, soggy mix. Let the surface dry between waterings and repot into a chunkier, faster-draining aroid blend.
• Leaf tip and edge browning — Dry air or fertiliser salt build-up. Increase humidity and flush the pot thoroughly every few months to clear excess salts.

Propagation

Easiest by division at repotting time: lift the plant and separate rooted offsets or side crowns, each with roots and a growth point. Cuttings carrying aerial roots will also root in a humid, airy medium. As a hybrid it will not come true from seed, so division preserves the cultivar. 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

Anthurium andraeanum 'Midori' is toxic to pets. ASPCA classifies Anthurium as toxic to cats and dogs. It contains insoluble calcium oxalate crystals (raphides) that, when chewed, embed in the mouth and cause intense oral irritation, drooling, vomiting, and trouble swallowing. Keep out of reach of pets and children and wash hands after handling. 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.
