    Features of Philodendron Melanochrysum

    Philodendron melanochrysum is a plant that stands out. Owners of this plant often take pride in displaying it, and it’s easy to see why. The Melano plant boasts stunning dark-green crystalline foliage with yellow venation that runs through the leaves. Additionally, the leaves have randomly distributed gold specks on their surface.What makes the Philodendron melanochrysum particularly interesting is that it is native to Colombia but can be found in Costa Rica, Peru, and the tropics of Ecuador. The name “melanochrysum” actually means “black gold,” likely due to the appearance of the plant.

    This unique plant is an excellent choice for a houseplant since it adds texture and vibrance to any room, sprucing up dull spaces.

    Appearance of the plant


    The Philodendron melanochrysum is a highly sought after plant due to its appealing appearance. Its lush foliage and scadent stems make it an ideal ornamental plant that can add life to any dull space and bring an element of the jungle into your home. The foliage of Philodendron melanochrysum is made up of scandent and slender stems that are approximately 10 cm long, robust petioles that are 9 to 15 cm long, and leaf blades that expand up to about 20 cm long and 12 cm wide. The leaves are elongated and heart-shaped, ranging in color from dark green to almost black. In the juvenile stage, the leaves are smaller and broader, while the velvety texture is highlighted by gold specks and light-green venations. Given a moss pole or any stake, the Philodendron melanochrysum can climb over time.


    Flowering occurs rarely in the cultivated Philodendron melanochrysum, and is considered an unimportant feature by most growers. The priority is usually placed on foliage development, with some even removing the floral initials to focus all the energy on lush foliage. In the wild, flowers can be observed in the form of a set of inflorescence covered by a spathe and accessorized by a spadix. However, the blooms are not as beautiful as the foliage, with colors ranging from light green to white. The blooming period usually occurs during early summer.

    Size of the plant

    The size of Philodendron melanochrysum can reach up to 26 feet, especially when climbing support such as a moss pole is provided. The growth rate of the plant is considered slow to moderate, increasing at a rate of approximately 8 to 12 inches during the growing season. If the growth rate of your Melano plant is not satisfactory, you can adjust the rate of fertilizer application while regularly pruning the spent foliages and decaying plant parts to ensure that your plant efficiently grows and develops more leaves.


    There is little report about Philodendron melanochrysum’s fragrance, or whether it has a recognizable scent. However, be aware of bacterial infections that can cause blackened soft lesions on the leaf surface, often accompanied by an unpleasant fishy odor. Prune off immediately the infected plant parts and wipe the leaves with alcohol or neem oil. Root rotting, often caused by overwatering, can also emit strange odors from the base of the plant. It is important to maintain a proper watering cycle to avoid this problem.

    How to care for Philodendron melanochrysum?

    Philodendron melanochrysums are native to the tropical areas of South America and thrive in warm surroundings with filtered light. For Melano plant care it is necessary to maintain temprature ,humidity level and consistent watering.

    Light requirement for Philo Melanochrysum

    The Philodendron melanochrysum typically requires dappled or partial sunlight, much like other Philodendrons, as it naturally grows as an understory plant in the wild. When kept indoors, it’s best to position the plant a few feet away from the window to ensure it gets the right amount of light. If growing outside, it’s important to provide the plant with some afternoon shade to avoid damaging the foliage due to excessive exposure to full sun. Those who have experience growing tropical ornamental plants should have no difficulty meeting the Melano plant’s light requirements.


    The Philodendron melanochrysum thrives in temperatures between 70 to 80°F (21-27°C). It lacks tolerance for cold temperatures, so keeping it below 60°F can impede its foliage formation and overall growth.The plant is suited for outdoor growth in USDA hardiness zones 9a to 11b, but if grown indoors, exposure to cold drafts should be avoided as it can harm and injure the plant.

    Maintaining the ideal temperature for the Melano plant will make it flourish and reach its full potential.

    Watering requirement for Philodendron melanochrysum

    When it comes to watering Philodendron melanochrysum, there is no set schedule.

    To avoid over-watering, it’s best to check the soil first by using your index finger to feel the top 2-3 inches. Once the soil is dry to that depth, which typically takes 7-8 days, you can water your Melano plant.

    The amount of sunlight and the season can also affect the watering needs of your plant. During summer, you may need to water more frequently, while during winter, you can reduce the frequency.

    It is crucial to use a pot with proper drainage and an appropriate potting mixture to prevent root rot.

    Repotting Melanochrysum Philodendron

    When it comes to Philodendron melanochrysum, repotting is typically necessary when it becomes rootbound or when its roots start to protrude from the base of the plant.

    The frequency of repotting may vary based on the plant’s growth rate and conditions. Expert tip: It is recommended to repot during spring or summer for a smoother transition.

    To begin, gather a potting mix and a container that is at least twice the size of the current pot. Fill the container halfway with soil, carefully place the root ball in the center, then fill in the remaining soil and water thoroughly.

    Humidity requirement

    When caring for the Philodendron melanochrysum, it’s essential to keep in mind the plant’s natural environment, which requires high humidity levels.

    To maintain this plant’s health, aim to keep humidity levels at or above 60%, taking care not to let it surpass the optimum range, as excess humidity can lead to pest infestations and disease.

    For optimal results, consider using a pebble tray as a solution for maintaining the ideal humidity levels for your Melano plant. Simply place the plant over a tray filled with pebbles and water, which serves as an efficient and practical method to provide consistent and appropriate levels of moisture.

    Adding occasional misting to your routine can also help keep your plant adequately hydrated.

    Fertilizing Philodendron Melanochrysum

    For optimal growth of the Philodendron melanochrysum, it is crucial to provide appropriate fertilizer during the active growth period.

    It is advised to use a balanced fertilizer with an NPK ratio of 20-20-20 and avoid cheap options that may lead to the accumulation of harmful minerals in the soil over time.

    In addition to chemical fertilizers, natural amendments like biochar and vermicasts can be used to enhance plant growth.

    As a pro tip, slow-release fertilizers are often preferred by novice gardeners as they are more efficient and beginner-friendly.

    Perfect Soil

    For the best soil for Philodendron melanochrysum, it’s recommended to create a mix that is light and airy, using fresh garden soil, peat moss, perlite, and charcoal.

    To improve the texture and drainage, you can also add in orchid bark. Alternatively, you can use a commercial orchid mix as the soil for your Melano plant. To prevent overwatering, it’s important to use a soil mix that drains well. This way, only the right amount of moisture will stick to the soil, preventing damage to the root system.

    Additionally, the recommended ph level for Melano plants is between 5.5 to 6.0, which is on the acidic side.

    Pruning Philodendron melanochrysum mature plant

    Pruning a Philodendron melanochrysum is usually done to remove spent foliage and decaying parts of the plant. However, if you are using it as a climbing plant, pruning may not be necessary.

    To properly prune the Melano plant, ensure that you use sterilized pruning shears or knives. Trim a few stems, approximately 25% of the plant, starting from the older leaves and stem. This will help to remove any infected parts and prevent the spread of disease to other houseplants.

    Additionally, it is beneficial to regularly wipe the leaves of the Melano plant to maintain its healthy appearance and vibrancy.


    Propagation of Philodendron melanochrysum can be easily achieved through stem cuttings. Firstly, select a healthy stem with a minimum of 2 to 3 small leaves and a leaf node. With sterile scissors or a grafting knife, separate the stem from the mother plant.

    In case you want to propagate the Melano plant in water, you need to remove some of the bottom leaves while keeping those on top intact. For rooting in soil, simply plant the cuttings. In any case, make sure that the new plants are exposed to ample light. This allows the roots to develop within 3 to 4 weeks.
