Philodendron Sharoniae (Sharoniae) care

Light

Bright but filtered. Philodendron Sharoniae burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Thrives in bright indirect light, which drives large, well-textured leaves; medium indirect is tolerated with slower growth. Shield it from direct sun, which burns the long, soft leaf blades. 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 philodendron sharoniae: when the top 2-3 cm of soil is dry, roughly every 7 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. Keep the mix evenly moist but never soggy, letting the surface dry slightly between waterings. The large leaves transpire freely, so it appreciates consistent moisture in the growing season.

Soil and pot

Philodendron Sharoniae grows best in rich, chunky aroid mix. Use an airy blend of orchid bark, perlite, coco coir and some compost for moisture retention with strong drainage. Slightly acidic, well-aerated soil supports its vigorous climbing roots. 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

Philodendron Sharoniae sits happiest at around 60-80% humidity and 18-29°C (65-84°F). A true high-humidity tropical that performs best at 60% and above; elevated humidity produces fewer leaf deformities and cleaner edges. Below 50% growth slows and new leaves may emerge malformed. 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 philodendron sharoniae sparingly. Feed every two to four weeks during spring and summer with a balanced liquid fertiliser at half strength to fuel its large foliage. Reduce in autumn and stop in winter when growth slows. 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 philodendron sharoniae in the Growli community. Each is annotated with the most common cause so you know where to start.

• Malformed new leaves — Low humidity and inconsistent watering cause crinkled or stuck new growth. Stabilise humidity above 60% and keep moisture even for clean, elongated leaves.
• Small juvenile leaves persisting — Without a support and adequate light the plant stays in juvenile form. Provide a moss pole and bright indirect light to trigger mature strap leaves.
• Yellowing leaves — Typically overwatering or poor drainage. Use a chunky aroid mix and let the surface dry between waterings.
• Brown leaf edges — Dry air or salt buildup scorches the long blades. Raise humidity and flush the soil periodically to remove excess fertiliser salts.

Propagation

Propagate from stem cuttings containing at least one node and an aerial root, rooting in moist sphagnum moss or water. High humidity and warmth speed rooting; spring and summer are the best times to take cuttings. 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

Philodendron Sharoniae is toxic to pets. ASPCA lists Philodendron as toxic to cats and dogs. All parts contain insoluble calcium oxalate crystals; chewing causes oral irritation, drooling, vomiting and difficulty swallowing. Keep this plant out of reach of 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.
