As a popular houseplant renowned for its vibrant and green leaves plus low-maintenance nature, the Philodendron Green Congo is no doubt a favourite among gardeners.
Native to the tropical rainforests of South America, this plant loves warm and humid environments. It has striking, glossy leaves with an upright growth habit that adds a touch of the tropics to any indoor space.
The Philodendron Green Congo belongs to the Aracea family, notable for plants like Monstera and the Peace Lily. This evergreen perennial can reach up to 2 feet in height and width, so you can use it for both small and large spaces.
The plant is also popular for beginners due to its low maintenance. Many who are interested in how to care for a Philodendron Green Congo find that it has great resilience and adaptability. Find out more about this lush plant in the following sections.
Light Requirements
When learning how to care for Philodendron Green Congo, one of the first things to note is its light requirements. This plant thrives in bright but indirect sunlight that mimics its natural habitat – under the canopy of the tropical rainforests of South America. It does not appreciate direct sunlight since it can scorch its leaves which will turn yellow or develop brown spots.
Place your Philodendron Green Congo near a window with sheer curtains. Or, position it in a well-lit room where it can receive diffused light throughout the day. If there is not enough natural light (usually in the winter), try investing in artificial grow lights to supplement your plant.
There are a few signs to look for when your plant is getting too much or not enough sun. If the leaves are yellowing with scorched edges, there’s too much light, as mentioned above. But, if the plant is growing slowly and the leaves are becoming smaller and losing their vibrant colour, then it needs more life. But, don’t immediately place it in a brighter location. Instead, gradually move the plant to the best place and monitor its response.
Caring for a Philodendron Green Congo also depends on the season. For instance, in summer, make sure to protect the plant from intense heat. Do this by moving it a few feet away from the window or sheer curtain. Meanwhile, winter means moving it closer to the light source to compensate for the reduced daylight hours.
Watering Needs
Since it comes from a naturally humid environment, having a consistent watering routine will be part of the steps on how to care for a Philodendron Green Congo. You need to remember to keep the soil evenly moist without letting it become waterlogged or completely dry.
One of the signs that you need to water your Philodendron Green Congo is when the top inch of the soil feels dry to the touch. To check for moisture, insert your finger into the soil. If it feels dry, then thoroughly water it until the water drains out of the bottom of the pot. This ensures that the entire root system receives hydration. Don’t forget to empty the drainage tray to prevent water from stagnating at the base, leading to root rot.
Your watering schedule will also depend on the season. Spring and summer, the growing months, means your plant needs to be watered more frequently. On the other hand, fall and winter known as the dormant period means reducing watering frequency. It is at this time that the plant’s growth is slow and requires less moisture. Look for signs of overwatering (yellowing leaves, etc) and underwatering (brown leaves, etc) and adjust your watering routine accordingly.
As mentioned above, the Philodendron Green Congo loves humid environments. So, mist the leaves regularly either by having a humidity tray or a humidifier nearby.
Soil and Potting
Another factor in learning how to care for Philodendron Green Cong is selecting the right soil and pot. A high-quality potting mix with aroid or a mix of peat, perlite, and orchid bark works very well for this plant. These mixes provide excellent aeration essential for preventing root rot and promoting healthy root development.
The pot you choose should have drainage holes to allow excess water to escape. Plus, it will prevent water from accumulating at the bottom causing root rot. Terra cotta pots are great since they are porous and allow for a better airflow best for a healthy root system.
When it comes to repotting, do so every one to two years or when you notice roots going out of the drainage holes. The best time to report is during spring or early summer when the plant is still growing. Start by gently removing the plants from their current pot. Then, shake off excess soil and trim any dead or damaged roots. Finally, place the plant in a slightly larger pot with fresh potting mix that covers the root ball adequately.
Fertilising
The Philodendron Green Congo benefits from regular fertilising, especially during its active growing season in spring and summer. A well-balanced, water-soluble fertiliser with an equal ratio of nitrogen, phosphorus, and potassium (such as a 20-20-20 formula) is very ideal for providing the right nutrients for the plant.
In terms of fertilising the plant, note that you should first dilute the fertiliser to half the recommended straight. Doing so will help you avoid over-fertilising which leads to nutrient burn and damage roots. Apply the diluted fertiliser mix every four to six weeks during the growing season. Also, fertilise when the soil is already moist to prevent the roots from being shocked by the sudden influx of nutrients.
Reduce the frequency of fertilising during the fall and winter months. During this period, only fertilise once every two to three months when the plant’s growth is slow and its nutrient requirement decreases. Over-fertilising at this time will cause salt buildup in the soil which in turn harms the plant.
Some of the signs to watch out for when your Philodendron Green Congo lacks nutrients are slow growth, smaller leaves, and an overall pale or yellowish colour. Excess nutrients meanwhile cause brown leaf tips and margins. Adjust your fertilising routine after noticing these signs.
Another part of knowing how to care for a Philodendron Green Congo is to occasionally flush the soil with water. This will remove any accumulated salts from the fertiliser. Plus, it promotes a healthy root environment and prevents nutrient imbalances.
Pruning and Maintenance
Regular pruning helps maintain the plant’s shape and prevent potential issues such as pest infestations and diseases. When you remove dead or damaged leaves, you allow the plant to focus more of its energy on producing new, vibrant leaves.
So, as part of the steps on how to care for a Philodendron Green Congo, how exactly do you prune the plant correctly? Fortunately, it’s a fairly straightforward process.
First, inspect the leaves for any yellowing, browning, or wilting. Then, use clean, sharp pruning shears to cut the leaves off at the base, close to the main stem. Follow this to prevent any potential spread of disease and improve the plant’s overall appearance. Make sure to sterilise your pruning tools before and after use to avoid transferring pathogens to the plant.
If you want a bushier growth in your plant, pruning can help. Simply cut back any overly long or leggy stems and this will encourage new growth from the base. Pruning also improves air circulation around the foliage, reducing the risk of fungal infections.
Wiping the leaves with a damp cloth to remove dust and debris should be part of your maintenance routine. Pay close attention to the undersides of the leaves, where pests like spider mites and aphids are likely to hide. If you spot pests, treat them immediately with insecticidal soap or neem oil.
Knowing how to care for Philodendron Green Congo mostly involves creating an environment that mimics its natural tropical habitat. From light, watering, fertilising, maintenance and more, we hope this ultimate care guide provided you with the basic knowledge you need to finally add this striking plant into your home or landscape design.
Remember that this plant requires bright, indirect light. Then, have a consistent watering routine to keep the soil evenly moist. Make sure to use the right soil mix and pot for proper drainage and root support. Provide regular balanced fertiliser, but take note of the seasons and adjust accordingly. Finally, do some pruning and maintenance to keep your plant in top shape while ensuring it is healthy and not infested with pests and diseases.
