Philodendron melanochrysum Care
Light
Philodendron melanochrysum prefers bright, indirect light. Avoid direct sun, as it can burn the delicate leaves. A north or east-facing window is ideal for providing the right amount of light.
Soil
A well-draining, peat potting mix is ideal for this Philodendron. Add perlite, orchid bark, or coco coir to improve drainage and aeration.
Water
Keep the soil consistently moist. Water your Philodendron when the top 1-2 inches of soil are dried out. Reduce watering cadence during the winter months when the plant is in its dormant phase.
Temperature
This plant prefers warm temperatures between 65-85°F (18-29°C). Avoid placing the plant near cold drafts, air conditioners, or heaters.
Humidity
High humidity is essential for Philodendrons. Maintain humidity level of around 50%. You can use a humidifier, place a pebble tray filled with water, or group your Philodendron with other moisture-loving plants.
Fertilizer
Fertilize your Philodendron every 4-6 weeks during the peak season with a slow-release, balanced fertilizer diluted to half strength. Don;t fertilize during the fall and winter months.
Pruning
Pruning Philodendrons can help maintain its shape and size. Regularly trim any yellow or damaged leaves, and remove any excessively long vines to encourage bushier growth. Use clean scissors or pruning shears to avoid damaging the plant.
Potting and Repotting Philodendron melanochrysum
Repot your Philodendron melanochrysum every 2-3 years, or when it becomes root-bound. Choose a pot that is slightly larger in diameter than the current pot, and ensure it has drainage holes. Spring or early summer is the best time to repot, as the Philodendron is actively growing.
How to Repot (Step-by-Step)
- Gently remove the Philodendron melanochrysum from its current pot.
- Inspect the roots for indications of rot or damage, and trim away any affected roots.
- Place a layer of fresh, well-draining potting mix in the new pot.
- Position the plant in the new pot, ensuring it is at the same soil level as it was in the previous pot.
- Fill the pot with more potting mix, gently pressing the soil around the roots to provide support.
- Water the repotted plant thoroughly, allowing the excess water to drain through the drainage holes.
- Place the repotted Philodendron melanochrysum in a bright, indirectly lit location.
Propagation
Philodendron melanochrysum can be easily propagated through stem cuttings. Here’s a step-by-step guide:
- Choose a healthy, mature stem with at least one or two leaves and a node (the swollen area where leaves and roots emerge).
- Using clean, sharp scissors or pruning shears, cut the stem just below a node.
- Remove any lower leaves, leaving only the top two or three leaves on the cutting.
- Dip in rooting hormone powder (optional, but it can encourage faster root development).
- Plant in pot of water.
- After 2-4 weeks, you should see roots developing from the node. Once the roots are about 1-2 inches long, the cutting is ready to be potted in soil.
- Dig up the soil and plant the cutting in a small pot filled with a well-draining potting mix.
Blooms
Philodendron melanochrysum, admired for its large, velvety leaves with a dark green hue, can also produce blooms under suitable conditions. However blooms rarely appear on indoor houseplants.
Toxicity
Philodendron melanochrysum, like other members of the Philodendron genus, contains calcium oxalate crystals that are toxic to humans and pets.
NOTE: This page is not intended as a substitute for veterinary advice. The toxicity of an ingested substance varies depending on the amount ingested, the animal’s weight, and its sensitivity to specific allergens. Contact your veterinarian or local animal poison control center immediately if you think your pet may have ingested a toxic substance.
Common Pests
Philodendron melanochrysum is relatively resistant to pests, but it can be affected by mealybugs, spider mites, and aphids. Inspect the Philodendron regularly for signs of infestation, and treat any issues promptly with insecticidal soap, neem oil, or a suitable pesticide.
AVOID
- Overwatering
- Placing under harsh sunlight
- Using poorly drained potting mediums
- Fertilizing during dormancy
Common Problems
Overwatering can also lead to root rot, which is a common issue with Philodendron melanochrysum. Ensure the plant is not sitting in waterlogged soil, and let the top 1-2 inches of soil dry out between waterings.
