Philodendron Melanochrysum, also known as black-gold philodendron, has velvety dark green leaves with yellow veins. It originates from Colombia.
This plant will propagate in both water and soil. Water propagation is my preference because you can see things happen as it grows!
Place your cutting in a jar/vase/tube of room temperature water. Make sure the nodes (small bumps on the plant) are submerged in the water.
Keep it somewhere that matches the light and temperature specifications shared below.
When propagating plants, it’s key to keep the humidity UP while the plants root. Higher humidity levels help boost the propagation process.
Change out the water once a week or when it looks murky, and top it up when needed. Fresh water will help oxygenate the cutting and prevent algae build-up.
Roots should start to develop within 3-4 weeks.
Pot the plant up when the roots are approximately 5cm long.
It will thrive in bright, indirect light. Avoid direct contact with the sun as this can burn the leaves.
This plant can start to grow ‘leggy’ (growing long strands of stem with little to no growth) if it isn’t getting enough light. If this is the case, move the pot to a lighter area of the house and cut the excess growth back.
The Melanochrysum prefers to grow in higher temperatures, so aim for 21-27℃.
This plant can grow with average room humidity, but it would do so much better in higher humidity conditions that mimic a rainforest. This can be achieved by using a humidifier, grouping plants together, or by growing the plant in a sealed mini greenhouse. A big cookie jar, clear tub or terrarium will do the trick!
It is a climber so you can use a moss pole or trellis to facilitate growth. As with most Philodendron, it’s important to use a well-draining potting mix that contains lotsa of bark and perlite. This plant should also be potted up in a pot that has drainage holes at the bottom. This plant does not like to be rootbound, so aim to re-pot it every 2-3 years.
Water thoroughly to mimic tropical jungle conditions and allow the water to drain through properly before returning the plant to its decorative pot. Wait for the soil to dry a bit before you water the plant again.
Invest in a moisture meter to help you monitor the levels of moisture in the soil so that you can only water it as needed.
As with most tropical plants, you should feed this plant during the growing season. Aim to feed it every second week.
Melanochrysum can be pruned to control their shape and size.
Cleaning your leaves regularly will help prevent any pests. Rosecare Spray or other alternatives can be applied if you come into contact with any pests.
