How to Grow and Care for Philodendron Gloriosum Variegated

The Philodendron Gloriosum Variegated is a collector’s plant known for its striking appearance. Its large, heart-shaped leaves have a velvety texture and display patterns of white, cream, or yellow variegation, making it a sought-after specimen among plant enthusiasts.

Unique Characteristics of Variegated Gloriosum

Unlike many philodendrons that climb, this variety is a terrestrial creeper. Its stem, or rhizome, grows horizontally along the surface of the soil, sending up leaves as it progresses. This growth habit is a defining characteristic and influences how it should be potted.

The variegation is known for being unstable, which contributes to its rarity and value. The patterns can appear as large patches, known as sectoral variegation, or as smaller splashes across the leaf. Because of reduced chlorophyll in the variegated sections, its growth is often slower than its non-variegated counterpart.

Essential Care Guide

Light

Proper lighting is a significant factor in maintaining the health and appearance of a variegated Gloriosum. It requires bright, indirect light to thrive, and an east-facing window that receives gentle morning sun is ideal.

Too much direct sunlight will scorch the delicate variegated portions of the leaves. Conversely, insufficient light can cause the plant to lose its variegation as it produces more chlorophyll to compensate, a process known as reversion.

Soil

A well-draining and airy soil mix is necessary to prevent water from saturating the roots. Standard potting soil is often too dense and can lead to root rot. An ideal mixture contains ingredients that promote aeration and drainage, such as orchid bark, perlite, and coco coir.

Some growers also add horticultural charcoal to the mix. Charcoal can help to absorb impurities and prevent the soil from becoming sour over time.

Watering

A consistent watering routine is important, but the plant is sensitive to overwatering. Allow the top one to two inches of the soil to dry out completely before watering again. You can check the moisture level by inserting a finger into the soil.

When it is time to water, do so thoroughly until water runs out of the drainage holes at the bottom of the pot. This method ensures the roots receive adequate hydration without sitting in waterlogged soil.

During the winter months, when the plant’s growth slows, you will need to reduce the frequency of watering. Always discard any excess water that collects in the saucer beneath the pot.

Temperature and Humidity

As a tropical plant, the Philodendron Gloriosum Variegated flourishes in warm and humid conditions. The ideal temperature range is between 65°F and 85°F (18°C to 29°C). It should be protected from cold drafts and sudden temperature fluctuations, so avoid placing it near open windows in the winter or directly in the path of an air conditioner.

This plant appreciates high humidity levels, ideally between 60% and 80%. Using a humidifier, grouping it with other plants, or placing it on a pebble tray filled with water are all effective ways to increase the ambient humidity.

Fertilizer

To support its growth during the spring and summer growing season, a regular feeding schedule is beneficial. A balanced, water-soluble fertilizer should be diluted to half-strength to avoid the risk of burning the roots and damaging the sensitive variegated leaves.

Feed the plant every 4-6 weeks while it is actively growing. In the fall and winter, you should reduce or stop fertilizing altogether as the plant enters a period of dormancy.

Propagation Methods

Propagating a Philodendron Gloriosum Variegated is done by taking a cutting from its rhizome. To begin, identify a healthy section of the rhizome that has at least one leaf and one or more nodes. Nodes are the points on the rhizome from which new roots and leaves will emerge.

Using a clean, sharp blade, make a cut on the rhizome between nodes. It is beneficial to allow the cut end of the rhizome cutting to callous over for a few hours to reduce the risk of rot.

Once you have your cutting, you can root it in a variety of mediums such as sphagnum moss, perlite, or water. Keep the medium consistently moist but not waterlogged. Placing the cutting in a warm, bright location with high humidity will encourage root development. Once a healthy root system has formed, the new plant can be potted into an appropriate soil mix.

Repotting a Crawling Philodendron

Repotting a Philodendron Gloriosum requires a different approach than for climbing houseplants to accommodate its crawling growth habit. A standard deep pot is a common mistake, as the rhizome will run out of surface area. The ideal container is long and rectangular, providing ample room for the rhizome to extend horizontally, allowing the plant to mature without frequent repotting.

When placing the plant in its new container, position the rhizome on top of the soil, not buried beneath it, as this can lead to rot. The roots should be settled into the soil, but the rhizome needs access to air and light.

Common Issues and Solutions

A loss of variegation, or reversion to green, is a response to insufficient light. To encourage the return of variegation, move the plant to a location with brighter, indirect light.

The delicate, non-pigmented sections of the leaves are susceptible to developing brown, crispy edges. This is a sign of low humidity, inconsistent watering, or exposure to excessive direct sunlight. Increasing ambient humidity and ensuring a consistent watering schedule can help prevent this issue.

This philodendron can be susceptible to pests such as spider mites, thrips, and mealybugs. Regularly inspecting the leaves, especially the undersides, can help you catch an infestation early. If pests are found, wipe the leaves with a damp cloth or use an insecticidal soap or neem oil solution.

Stunted growth or the production of smaller-than-usual leaves can indicate insufficient light, a lack of nutrients, or a need for repotting.
