The Philodendron Splendid is a stunning houseplant belonging to the Araceae family with heart-shaped foliage Philodendron Melanochrysum, or black-gold philodendron, is a rare vining plant with large, velvety green leaves and yellow veins. It needs warm, humid conditions and dappled sunlight.
Light
Philodendron Melanochrysum is a plant that naturally grows beneath the forest canopy where it receives filtered, indirect light, similar to its natural habitat. To prevent leaf damage, it’s important to avoid placing it in direct sunlight. As an indoor plant, it should be positioned in an east-facing or north-facing window where it can receive bright, indirect light. Insufficient light can cause the plant to grow leggy, while too much direct sunlight can burn the leaves. Leggy growth is the result of insufficient light and lack of support. Keep in mind that this is a vining Philodendron that generally grows in the understory of jungles. If you use grow lights, placing the plant about six inches away from the light is best.
Water
To keep your Philodendron Melanochrysum healthy and thriving, it’s important to water it regularly. You should water your plant when the top 2-3 inches of soil feel dry to the touch, which usually happens every 7-8 days. You can check the soil moisture level using a chopstick or finger. However, keep in mind that you may need to adjust the watering frequency based on the season and the amount of sunlight your plant receives. Overwatering can lead to root rot, so it’s crucial to avoid it. You should use a pot with sufficient drainage holes and a suitable potting mix to ensure proper drainage. You should reduce watering during winter as the plant’s growth slows down.
Soil
When choosing a potting mix for your Philodendron Melanochrysum, selecting one that is both well-draining and moist, with a high organic content, is crucial. For this purpose, pure sphagnum moss is an excellent option as it is organic, airy, and retains water efficiently. However, one should be careful while watering the plant because sphagnum peat moss, although airy, can sometimes hold too much water. To create your own soil mixture, combine equal parts of peat moss, orchid bark mix, perlite, and charcoal to achieve the desired consistency. Make sure that the soil pH is between 5.5 and 6.0.
Temperature
This plant needs a warm environment to grow optimally, with temperatures ranging between 70-80°F (21-27°C). It cannot tolerate cold temperatures below 60°F, so avoid exposing it to cold drafts and fluctuating temperatures. You can grow this plant outdoors if you live in USDA hardiness zones 9a to 11b. During summer, it is safe to keep the plant outside. However, if you live in an area where winter temperatures drop below 60°F, you should always keep the plant in a warm environment, primarily if you reside in an area with harsh winters.
Humidity
A Philodendron Melanochrysum can survive without high humidity but can suffer from wilting, drooping, browning, and curling leaves if the humidity is low. Ideally, the humidity should be above 60%. You can use a humidifier to increase the humidity level or group your plants together. Another option is to place a pebble tray under the pot, which can also help to increase the humidity.
Fertilizer
Proper soil nutrition is essential for maintaining the health of Philodendron Melanochrysum. To keep it healthy, you should fertilize it regularly during its active growth period. It is recommended to use a balanced NPK 20-20-20 fertilizer. Avoid using low-quality fertilizers as they can accumulate in the soil over time, leading to toxic build-up of minerals such as iron and aluminum. You can also use natural amendments such as biochar and vermicasts to promote growth. When fertilizing, ensure the soil is moist and water it first if necessary, as dry soil and fertilizer can harm the plant’s roots. Apply liquid fertilizer lightly and frequently, once a month, for optimal growth.
Tip: A slow-release fertilizer is preferred by home gardeners as it is more efficient and beginner-friendly.
Growth Rate
Philodendron Melanochrysum is a plant that grows slowly to moderately, producing a new leaf every few months. When grown indoors, it can reach a height of three to five feet (90-150cm), whereas when cultivated outdoors, it can grow up to 20 feet (6m) tall. The plant’s leaves are massive, growing up to two feet in length. Due to their size, it is advisable to have a spacious room that can comfortably accommodate both the plant’s height and the length of its leaves.
Pet Safety
Toxic to humans and pets, ingestion can lead to health issues. Handle with care and keep children and pets out of reach.
Grow in Semi-Hydro
- Philodendrons, celebrated for their lush foliage and adaptability, thrive in semi-hydroponic systems such as LECA/Pon, thanks to their resilient root systems and preference for consistent moisture.
- Shifting a Philodendron to a semi-hydroponic setting works well using a Nutrient Stagnant Wicking (NSW) method, providing a stable and effective environment for growth.
- Within the LECA/Pon environment, Philodendron roots adapt swiftly, effectively managing any early challenges in adapting to the NSW system.
- For nourishing Philodendrons in semi-hydro systems, a nutrient solution with a concentration around 800-1000ppm is optimal.
- Philodendrons are versatile in adapting to a range of temperature and humidity levels, making them ideal for various indoor settings.
- Regular care involves keeping an eye on the water level in the reservoir and periodically flushing the system to ensure the Philodendron’s healthy and consistent growth.
- If your Philodendron is a climber, it’s a must to look at our Moss Pole guide to have a proper set-up.
Tips
- Pruning for Shape and Size: Regular pruning controls size, shape, and legginess.
- Flower Management: Remove blooms to conserve the plant’s energy.
- Rapid Growth Potential: While it grows rapidly in the wild, indoor plants generally stay smaller.
- Pest Control: Watch for scale, spider mites, and aphids; treat with insecticidal soap or neem oil.
- Support Needs: Due to its height and leaf size, use a moss pole to support its weight
By adhering to these detailed care instructions, you can enjoy the beauty and growth of your Philodendron Melano plant. Consistency and attention to the plant’s needs are key to its health and vitality.
Happy planting! 🌱
