If you have a mature plant, you may get the chance to see it bloom—although their blooms are not nearly as spectacular as their velvet foliage. In fact, many growers choose to cut off the green flower spathes in order to redirect the plants energy back to their beautiful foliage.
Light
Philodendron melanochrysum naturally grow as forest understory plants where they receive dappled, indirect light. When grown indoors, it is best to try and replicate these conditions by choosing a location for your melanochrysum that receives bright, indirect light. Avoid exposing these tropical plants to prolonged periods of direct sunlight as the leaves can burn easily.
Soil
When it comes to choosing the right potting medium for your philodendron melanochrysum, stick to mixtures that are well-draining but moist, and high in organic content. Many growers choose to grow their philodendron melanochrysums in pure sphagnum moss as it is organic, airy, and retains water well. Alternatively, you can make your own soil mixture at home by combining one part peat moss, one part perlite, and one part orchid bark mix.
Water
These tropical plants require regular watering in order to grow well. As a general rule, you should water your philodendron melanochrysum once the top 2 to 3 inches of soil has dried out. Water your plant thoroughly until water drains from the pot’s drainage holes.
Temperature and Humidity
Philodendron melanochrysum grow well in standard household temperature and humidity levels. However, they grow best in above-average humidity where possible. If you have a greenhouse or can place a humidifier near your plant—it will appreciate it!
Fertilizer
Nutrient-rich soil is important to the health of the philodendron melanochrysum, and they benefit from regular fertilization during their active growing period. Use a balanced liquid fertilizer once a month from the early spring to the late summer.
Propagating Philodendron Melanochrysum
As with most vining philodendrons, philodendron melanochrysum are easy to propagate by stem cuttings. This is a great way to reuse any trimmings that are left over from pruning and create new plants for yourself or your friends. Here’s how you can propagate your philodendron melanochrysum in a few easy steps:
Common Pests & Plant Diseases
When grown indoors, philodendron melanochrysum are relatively well-protected from most pests and diseases. That being said, watch out for signs of common houseplant pests such as scale, mealybugs, fungus gnats, and spider mites; and diseases such as root rot, bacterial leaf spot, and fungal infections.
Common Problems With Philodendron Melanochrysum
Common problems with philodendron melanochrysum are usually a result of improper light or watering. Luckily, these plants are pretty resilient and if the issue is caught early enough, it is likely that they will make a full recovery.
Yellowing Leaves
Overwatering is the most common cause of yellowing leaves on a philodendron melanochrysum. Cut off any affected leaves and ensure that you allow the top couple inches of soil to dry out between waterings.
Browning Leaves
Brown, crispy leaves are usually an indication that your plant is not receiving enough moisture, or it is getting too much direct light (i.e. sunburn). Sometimes however, older leaves turning brown and falling off are just a natural part of the leaf’s life cycle and are no cause for concern. If you notice newer leaves developing brown spots, this is a larger cause for concern.
Leggy Growth
Leggy growth is a common issue for many vining plants, and is an indication that your plant is not receiving enough light. Choose a spot that receives at least 6-7 hours of bright, direct sunlight.
