Introduction
Welcome to our guide on growing and caring for the captivating Philodendron Shangri-La (Thamatophyllum bippinatifidum ‘Shangri-La’). With its compact size and deeply lobed leaves, this bushy and shrub-like philodendron adds a touch of elegance to any indoor space. In this article, we will explore essential aspects of nurturing this plant, including care tips, propagation techniques, potting and repotting guidance, common pests, and troubleshooting advice. Let’s dive in!
Philodendron Shangri-La Care
Philodendron Shangri-La is known for its low-maintenance nature, making it an excellent choice for both inexperienced and seasoned indoor gardeners. This tropical plant thrives in the warm, moist conditions found in rainforest understories. Unlike its climbing/vining relatives, this self-heading variety does not require a moss pole or trellis, nor does it need regular pruning. Although it occasionally produces spathe-like flowers during spring and summer, blooming is uncommon when grown as a houseplant.
Light
For optimal growth, provide your philodendron Shangri-La with bright to medium indirect light when kept indoors. While it can tolerate low light conditions, it may exhibit slower growth and develop a leggy appearance. When moving the plant outdoors in warmer months, ensure it is shielded from direct sunlight to prevent sunburn. Ideally, place it in a shady or partially shaded location.
Soil
Choose a loose and chunky potting medium to promote healthy growth. Specialty houseplant shops offer pre-made soil mixes designed for aroids, or you can create your own blend at home. A combination of equal parts indoor potting soil, perlite, and orchid bark mix provides a rich and well-draining environment that your philodendron Shangri-La will adore.
Water
Maintain a watering routine that allows the top half of the soil to dry out between waterings. When watering, ensure thorough saturation while allowing excess water to drain completely. Overwatering or prolonged exposure to soggy soil can lead to root rot, a common issue among philodendrons. Therefore, it is crucial to use pots with drainage holes and provide proper drainage.
Temperature and Humidity
Philodendron Shangri-La thrives in warm temperatures and average to high humidity levels. This resilience makes it an ideal choice for indoor cultivation. Keep the temperature between 60 and 75 degrees Fahrenheit, avoiding exposure to temperatures below 50 degrees Fahrenheit. Although the plant can adapt to standard household humidity, it benefits from additional moisture. Consider placing a small humidifier nearby or selecting naturally humid areas like bathrooms or laundry rooms.
Fertilizer
To support new growth, apply a balanced houseplant fertilizer diluted to half-strength during the spring and summer months. Feed the plant once a month while watering, and discontinue fertilization as autumn approaches and temperatures begin to drop.
Propagating Philodendron Shangri-La
The most effective way to propagate philodendron Shangri-La is through division. This method is easiest when working with a mature and healthy plant that has numerous offshoots growing in its pot. While stem cuttings can also be used for propagation, they may damage the plant due to its growth habit. For successful division propagation, follow these steps:
- Gently remove the plant from its pot and lay it on a flat surface.
- Loosen the soil around the plant’s roots and offshoots, taking care to preserve as many roots as possible.
- Separate the offshoots from the main plant, ensuring each offshoot has its own root system. Even if it only has a few roots, it should be viable. In some cases, an offshoot may still be connected to the mother plant by one large root. Use a sharp and sterilized cutting tool to separate it.
- Prepare small potting containers filled with loose and chunky soil mix for each offshoot.
- Plant each offshoot in its designated pot, firmly patting the soil around the stem.
- Water the newly potted plants thoroughly and place them in a warm location with medium to bright indirect light.
- Lastly, repot the mother plant in its original container, adding fresh potting soil if necessary. Return it to its original location and water as needed.
Potting and Repotting Philodendron Shangri-La
Philodendron Shangri-La can tolerate slightly root-bound conditions but should be repotted every one to two years or when it outgrows its current container. Signs indicating the need for repotting include roots emerging from drainage holes or encircling the pot. Repotting is best performed during the active growth period in spring or summer, although it can be done whenever necessary. Follow these steps for successful repotting:
- Choose a new pot that is two to four inches larger than the current one.
- Carefully remove the plant from its pot, ensuring minimal harm to the roots.
- Refresh the soil by replacing as much as possible without damaging the roots.
- Immediately return the plant to its original location.
Common Pests and Plant Diseases
Like most houseplants, philodendron Shangri-La is susceptible to common pests and diseases. Regularly inspect your plant to detect potential infestations early. Watch out for spider mites, fungus gnats, thrips, and mealybugs. In case of an infection, isolate the affected plant and treat it with neem oil or an appropriate insecticide.
Additionally, the philodendron Shangri-La is prone to fungal leaf spot diseases, which are common among philodendron species. These diseases manifest as small black or rust-colored spots on the leaves, gradually spreading to new growth. Treating these fungal diseases can be challenging, and they have a tendency to quickly spread to other plants. Isolate affected plants and use a fungicide for treatment.
Common Problems With Philodendron Shangri-La
Although philodendron Shangri-La is a resilient houseplant, certain issues can arise during indoor cultivation. Familiarize yourself with the following common problems:
Yellow Leaves
Yellowing leaves may indicate improper watering or lighting conditions. Older leaves naturally turn yellow and eventually drop. If new growth exhibits yellowing, adjust your watering and fertilizing routines accordingly. Consider relocating the plant to an area with better lighting conditions.
Brown Spots
Brown spots on the leaves can stem from several causes. Multiple small spots are often indicative of fungal infections, while one or two larger spots that are crispy and dry suggest sunburn or inadequate humidity. To remedy this, move the plant away from direct sunlight and drafty areas, as they can dry out the air.
FAQ
Q: How large does the philodendron Shangri-La grow?
A: Shangri-La philodendrons reach a height of 3 to 4 feet and span 4 feet in width.
Q: Is the philodendron Shangri-La considered rare?
A: No, although it may be less common than other philodendron varieties. It’s important to specify “Shangri-La” when purchasing to avoid any mislabeling or confusion with similar-looking philodendrons like Xanadu or tree philodendron.
Q: Should I mist my philodendron Shangri-La?
A: It is not recommended to mist the plant. Water left on the leaves can promote fungal infections. Instead, increase humidity around the plant by using a humidifier or placing it in a naturally more humid area of your home, such as a bathroom or laundry room.
