Philodendron gloriosum, a mesmerizing plant native to Colombia, is a stunning addition to any houseplant collection. With its heart-shaped, velvety leaves, this plant is sure to catch your eye.

Unfortunately, it has been classified as a vulnerable species in its natural habitat. However, by adding it to our home collections, we can both enjoy its beauty and contribute to its conservation.

In this comprehensive care guide, we will explore 5 essential care tips for Philodendron gloriosum, as well as provide insights into propagation and answer frequently asked questions.

Section 1: Lighting

Philodendron gloriosum is a versatile plant when it comes to lighting requirements. To encourage larger leaves, provide plenty of bright indirect light. Placing the plant in front of a window without direct sunlight is ideal.

If your window receives excessive sunlight, you can filter or diffuse it with sheer curtains or partially closed blinds. Insufficient light will hinder growth, so consider supplementing with a grow light if your conditions are particularly dim.

Remember, this plant already has slow growth, so providing optimal lighting conditions is crucial for best results.

Section 2: Watering

Proper watering is essential for the health of Philodendron gloriosum. Always water thoroughly and allow excess water to drain away. To avoid overwatering, ensure the top 1-2 inches of soil have dried out before watering again.

Checking the moisture level with your finger is a practical way to determine when to water. Using a well-draining potting mix and a pot with drainage holes will help prevent waterlogged soil and root rot.

Section 3: Temperature & Humidity

Philodendron gloriosum thrives in warm temperatures, so avoid exposing it to temperatures below 55F (13C). Ideally, maintain a temperature range of 65-85F (18-29C).

This plant appreciates high humidity, especially during the winter months when forced air heat can dry out the air. Aim for a relative humidity of 50-60% in your home by using a humidifier.

Avoid using misters as they only wet the leaves without increasing humidity. Additionally, ensure good air circulation to prevent stagnant, humid air, which can lead to fungal issues.

Section 4: Potting Mix & Pot Type

Choosing the right potting mix and pot type is crucial for the health of Philodendron gloriosum. This plant prefers a loose, well-draining potting mix.

A traditional aroid potting mix, consisting of equal parts all-purpose potting mix, orchid bark, and perlite, is suitable. However, depending on your conditions, this mix may dry out quickly.

If this is the case, you can experiment with using miracle gro moisture control mix or adjusting the ratios of your preferred all-purpose mix, orchid bark, and perlite.

When selecting a pot, opt for a wider pot rather than a deep one to accommodate the plant’s horizontal growth. Always ensure the pot has drainage holes to prevent water accumulation and root rot.

Section 5: Fertilizer

Fertilizing Philodendron gloriosum is essential for its overall health and growth. A recommended liquid fertilizer is Dyna-Gro Grow, which is urea-free and contains all the necessary micro and macro nutrients.

Dilute the fertilizer and apply it with every watering during the growing season. A ratio of 1/4 to 1/2 teaspoon of Dyna-Gro Grow per gallon of water is sufficient. Regular fertilization will promote healthy foliage and vibrant growth.

Section 6: Propagation

Propagation of Philodendron gloriosum differs from vining plants. This species grows from a rhizome, an underground stem, which produces new growth.

To propagate, use sterilized pruners to cut the rhizome into sections, ensuring each section has one or two leaves. Pot the individual sections in a suitable potting mix and provide higher humidity during the establishment phase.

Using a clear plastic bag or a humidifier can help create the necessary humidity levels. Check out the selection of Philodendron gloriosum on Etsy if you’re looking to purchase this stunning plant.
