The Philodendron giganteum ‘Blizzard’ is a popular cultivar of the Philodendron giganteum species, native to the tropical rainforests of Central and South America. This plant is known for its large, paddle-shaped leaves. Adorned with striking, unpredictable patterns of creamy white, light green, and medium green variegation, each leaf resembles a snow blizzard. Its distinct variegation makes it a favorite among plant collectors and an eye-catching addition to any indoor space.
Caring for Philodendron Giganteum ‘Blizzard’
Light Requirements
The Philodendron giganteum ‘Blizzard’ thrives in bright, indirect light. An east or north-facing window provides suitable light. Direct sunlight can scorch its large, variegated leaves, leading to yellowing or brown spots. Insufficient light can cause variegation to fade, leading to smaller leaves and slower growth. If natural light is limited, a grow light can supplement its needs.
Watering Techniques
Consistent, balanced watering is important. Keep soil moist but not waterlogged to prevent root rot. Water the plant when the top 1-2 inches of soil feel dry to the touch. Wilting leaves can indicate underwatering, while yellowing leaves with soggy soil often signal overwatering. During fall and winter, reduce watering frequency.
Soil Mix Preferences
An ideal soil mix is well-draining, airy, and rich in organic matter, retaining moisture without saturation. A suitable aroid mix often includes peat, perlite, and orchid bark for aeration and drainage. Coco coir or sphagnum moss can also be added for porosity. This prevents waterlogging and promotes healthy root development.
Temperature and Humidity Needs
This tropical plant prefers warm temperatures, ideally 65-80°F (18-27°C). Avoid temperatures below 55°F (13°C) to prevent slowed growth and foliage damage. High humidity, 60% or above, is also important. Low humidity can cause brown leaf edges and hinder larger leaf production. Increase humidity with a humidifier, pebble trays, or by grouping plants.
Fertilization Schedule
Fertilize during the active growing season (spring and summer) to support vigorous growth. Use a balanced, water-soluble fertilizer, such as a 20-20-20 formula, once a month. Dilute the fertilizer to half-strength to prevent root burn or affected variegation. During fall and winter, when growth slows, reduce fertilization to once every 6-8 weeks or stop.
Providing Support
This climbing philodendron benefits from vertical support as it matures. A moss pole or trellis allows aerial roots to attach, mimicking its natural growth habit. Climbing encourages larger, more magnificent leaves. Moss poles retain moisture, aiding aerial roots in gripping. This support promotes healthier growth and manages plant size indoors.
Repotting Your Philodendron Giganteum ‘Blizzard’
Repot when the plant shows signs of being root-bound, like roots growing from drainage holes or circling the pot. Stunted growth despite proper care also indicates a need. The best time to repot is during the growing season (spring or early summer) when the plant is active and recovers quickly.
Choose a new pot only 1-2 inches larger in diameter to avoid overwhelming the plant with too much soil. Ensure it has adequate drainage holes. Gently remove the plant, loosen circling roots, and place it in the new pot with fresh, well-draining soil. Water thoroughly after repotting to settle the soil.
Propagating Philodendron Giganteum ‘Blizzard’
Propagate through stem cuttings, a common method. The ideal time is during the active growing season (spring through early summer) for faster root development. Select a healthy stem with at least two nodes (where leaves and roots emerge).
Using clean, sharp shears, cut about 4-6 inches long just below a node. Remove leaves from the bottom node, as this part will be submerged. Cuttings can be rooted in water or moist, well-draining soil.
For water propagation, submerge the node in a jar of water, changing it every few days. If rooting in soil, bury the bottom node. Roots typically develop within weeks; once several inches long, move the new plant to a larger pot.
Troubleshooting Common Issues
Common issues relate to environmental conditions or pests. Yellowing leaves can signal overwatering (soggy soil), too much direct light, or nutrient deficiency. Crispy yellow leaves may indicate underwatering. Adjusting watering and light often resolves these.
Browning leaf tips or edges often indicate low humidity, which this tropical plant prefers. Increase humidity with misting, humidifiers, or pebble trays. Stunted growth or variegation loss suggests insufficient light; move the plant to a brighter, indirect location.
The plant can be affected by common houseplant pests like spider mites, aphids, or mealybugs. Signs include webbing (spider mites), tiny green/black bugs (aphids), or cottony white masses (mealybugs). Treat promptly with insecticidal soap or neem oil, or by physically wiping off pests. Good air circulation also prevents fungal diseases.
