The Philodendron Joepii is a rare, tri-lobed, pointy-leaved green plant named after Dutch botanist Joep Moonen. It was discovered in 1991 and has since become famous as a houseplant.
Light
The Philodendron Joepii plant grows best in medium to bright indirect sunlight and changes its leaf color according to the light it receives. In its natural habitat, the Amazon rainforest, it grows under a canopy, which filters the sunlight it receives. This plant is sensitive to direct sunlight, which can damage its leaves. However, it requires sufficient light to maintain its vibrant color and avoid leggy growth. To ensure proper growth, it is recommended to position the plant near east or west-facing windows and use sheer curtains to diffuse direct sunlight.
Water
Philodendron Joepii plant has unique roots that can store water efficiently, making it excellent at absorbing moisture from its surroundings. To water the plant, wait until the top inch or two of the soil is dry, then water it. However, it’s essential to avoid overwatering the plant as it can lead to root rot. The frequency of watering will vary with the seasons, and less watering is required in winter. It’s crucial to plant the Philodendron Joepii in well-draining soil and make sure that the pot has adequate drainage holes.
Soil
For the health of your Philodendron Joepii, it is important to use a soil mix that drains well. The recommended soil mix should consist of perlite, peat moss, vermiculite, and organic matter. This will ensure proper drainage and nutrient availability for your plant. Avoid overwatering to prevent root rot. The ideal pH range for the soil is between 4.5 and 7.5. Additionally, adding coarse sand, moss, and bark to the soil mix can enhance its structure and provide the necessary aeration for your plant.
Temperature
Philodendron Joepii is a tropical plant that requires a specific temperature range for optimal health and growth. The ideal temperature range for this plant is between 60-80°F (15-27°C), which mimics its natural habitat in the South American rainforests. It’s important to keep the plant away from cold temperatures, particularly below 50°F (10°C), as it can damage the foliage and stunt its growth. If you live in a cooler climate or during winter, it’s crucial to move the plant to a warmer indoor spot where it can still receive sufficient indirect light. Furthermore, avoid exposing the plant to sudden temperature changes, as it can cause stress and lead to leaf drop or other growth issues.
Humidity
Maintaining high humidity levels is crucial when taking care of Philodendron Joepii. This plant thrives in a rainforest environment, where it experiences almost-saturation humidity levels. However, it can be quite challenging to replicate such an environment in a typical home. To ensure that your Philodendron Joepii gets the required moisture, try to maintain the humidity levels above 60%. There are several ways you can increase humidity around the plant, such as placing it on a tray filled with pebbles and water, grouping it with other plants to create a microclimate, or using a humidifier. Occasionally misting the plant is also beneficial, particularly in dry climates or seasons. However, be careful not to overdo it since excessive moisture can lead to fungal issues. Having good air circulation is also vital to maintaining the right humidity levels without encouraging mold or mildew growth.
Fertilizer
Fertilization plays a vital role in promoting healthy growth and lush foliage of Philodendron Joepii. Use a balanced and water-soluble fertilizer during the active growing seasons of spring and summer. It’s recommended to dilute the fertilizer to half the recommended strength to avoid over-fertilization, which can harm the plant. Fertilize the plant once a month in these growing seasons. During the dormant winter months, decrease or stop fertilization as the plant’s growth rate naturally slows down. This approach ensures that Philodendron Joepii receives the necessary nutrients without the risk of nutrient overload.
Growth Rate
The Philodendron Joepii is a plant that grows slowly when kept indoors. Its unique tri-lobed leaves gradually develop and can reach lengths of up to 70 cm. The petioles that support the leaf blades can grow between 10 to 40 inches (0.2m to 1m). If you want to speed up its growth, creating greenhouse-like conditions, such as higher humidity and controlled temperatures, can help. However, it’s important to note that even with optimal care, the Philodendron Joepii remains a relatively slow-growing plant compared to other Philodendron species.
Pet Safety
Philodendron Joepii is toxic to cats and dogs if ingested. It contains calcium oxalate crystals that can cause mouth, tongue, and digestive tract irritation and swelling. If your pet eats any part of the plant, seek veterinary advice immediately. Keep the plant out of pets’ reach for safety.
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 monitoring the reservoir’s water level 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
- Ensure the cuttings are callused before propagating in water or soil to prevent rot.
- Regular pruning can encourage fuller growth and maintain shape. Use sterilized tools for this.
- Watch out for pests like mealybugs and spider mites, and treat them with alcohol wipes or insecticidal soap.
- Repot when the plant becomes root-bound or the soil dries out quickly. Use a larger pot with proper drainage.
- In case of overfertilization, leach the soil and consider repotting
To care for a Philodendron Joepii, provide medium to bright indirect light, water regularly, ensure well-draining soil, maintain warm temperature and high humidity, and fertilize monthly. Following these guidelines will help grow this rare plant and add beauty to your indoor plant collection.
Happy planting! 🌱
