Part of my complete Philodendron Care Guide: light, water, problems, every variety, and propagation in one place.
Philodendron Gloriosum Care at a Glance
| Care | What it needs |
|---|---|
| Light | Bright, indirect light; no direct sun |
| Water | When the top inch of soil is dry; never soggy |
| Soil | Chunky, well-draining aroid mix |
| Planter | Wide and shallow, because the rhizome crawls along the surface |
| Humidity | High, 60 percent or more |
| Temperature | 18 to 27 C (65 to 80 F) |
| Toxicity | Toxic to cats, dogs and people |
Is your Gloriosum crawling right out of her pot, or pushing out small leaves? Well, you’re not alone, this plant does things her own way. Mine tripled in size in nine months, and I had to repot her twice as she outgrew her pots! Below I share my Philodendron Gloriosum care routine: light, watering, humidity, the right planter, feeding, propagation and pests.

Understanding Philodendron Gloriosum in the Wild
Philodendron Gloriosum is native to Colombia, where it creeps across the humid forest floor in dappled light. Unlike climbing philodendrons, it crawls horizontally, so at home giving it room to spread is just as important as light and moisture.
How Much Light Does Gloriosum Need?
Philodendron Gloriosum thrives in bright, indirect light. In my northern‑hemisphere home, I started mine by a northeast window, where it received gentle morning sun. Later, I moved it to a south‑facing spot with UV‑filtered glass, which accelerated leaf size and production. Too little light results in smaller leaves and slower growth; too much direct midday sun can scorch the foliage. Aim for a balance: morning or late‑afternoon direct rays filtered through a sheer curtain are ideal. Rotate your plant every 10 days to ensure even growth and prevent it leaning toward the light source. See my short video below:
How to Water Philodendron Gloriosum
She likes consistent moisture, but never waterlogged soil. I water when the top inch or two of soil feels dry, delivering a thorough soak until water drains freely. In brighter, warmer months, this might mean more frequent watering; in cooler seasons, reduce to prevent soggy conditions that invite root rot. When in doubt, err on the side of underwatering. Gloriosum tolerates slight dryness far better than standing water.
Temperature and Humidity
Mirroring its rainforest home, Philodendron Gloriosum prefers temperatures between 65 °F and 80 °F (18 to 27 °C) and humidity above 60 percent. Keep it away from cold drafts, air conditioners, or radiators. When indoor air dries out in winter, boost humidity by grouping plants on a pebble tray or running a humidifier nearby. Avoid misting foliage, as trapped moisture can encourage fungal issues. High humidity encourages larger, healthier leaves and more vigorous crawling growth.
The Right Planter and Soil Mix
Because Gloriosum is a crawler, it favors wide, shallow pots over deep containers. I repotted mine twice in nine months, each time choosing a pot that accommodated its spreading stems. Always select a pot with drainage holes to prevent waterlogging and gently loosen old soil only as needed to protect delicate roots. For soil, I use a custom aroid mix of coco coir, perlite, and orchid bark: light, airy and well‑draining. To see exactly how I prepare this blend step by step, check out my DIY guide on Soil-Free Aroid Potting Mix recipe. A ready‑made aroid or tropical mix also works well so long as it’s not overly compact.
Do the Leaves Need Support?
The rhizome itself should stay on the soil surface, never climbing a pole. But as the large leaves mature, their weight can make the petioles flop onto the soil. A discreet stake or clip gives a heavy leaf a gentle lift, keeps it off the wet mix and lowers the risk of pests and fungal spots.
How to Fertilize Philodendron Gloriosum
Feed your Gloriosum monthly from spring through autumn with a balanced 20‑20‑20 liquid fertilizer at half strength. Always water before fertilizing to prevent root burn. During winter dormancy, pause feeding or reduce to once every two to three months, because overfeeding in low‑growth periods can lead to salt buildup and burned roots.
If your plants need a mild nutrient boost without risking overfertilizing, rice water can be a great option. Learn how to use it safely here.
How to Propagate Philodendron Gloriosum
When your Gloriosum’s crawling stem produces aerial roots and visible nodes, propagation is simple. Cut a section containing at least one node and either place it in water or plant directly into moist aroid mix. Roots usually form within two to four weeks; then, you can transplant water‑rooted cuttings into soil. This technique helps manage size and expand your collection.
Pests and Diseases to Watch For
Although generally robust, your Philodendron Gloriosum can attract spider mites, mealybugs, or scale. Inspect stems and leaf undersides regularly, wiping foliage with a damp cloth and treating infestations promptly with neem oil or insecticidal soap. Prevent root rot by avoiding overwatering and ensuring good drainage; maintain air circulation to deter fungal diseases. Normal yellowing of older leaves is part of the plant’s lifecycle, so simply trim these off to promote fresh growth.

Frequently Asked Questions
How do you care for Philodendron Gloriosum?
Give it bright indirect light, water when the top inch of soil is dry, a chunky aroid mix and high humidity. Because it crawls, use a wide, shallow planter and keep it warm.
Does Philodendron Gloriosum climb or crawl?
It crawls. The rhizome grows along the soil surface, so a long, wide, shallow planter suits it far better than a tall pot.
Why are my Gloriosum leaves small?
Usually low light or humidity, or a cramped pot. Give bright indirect light, 60 percent or more humidity, and room for the rhizome to crawl.
How often should I water Philodendron Gloriosum?
When the top inch of soil is dry. It likes lightly moist but never soggy soil, which causes root rot.
Is Philodendron Gloriosum toxic to pets?
Yes, it is toxic to cats and dogs, so keep it out of reach of pets and children.
