Everything it needs
9 essentials at a glance
Watering
Philodendron Plowmanii prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the pot has good drainage to prevent root rot. In the fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and a mushy stem, while under-watering may cause leaf droop and crispy edges.
Light
This plant thrives in bright, indirect light but can tolerate lower light conditions.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Avoid direct sunlight, which can scorch the leaves. If placed in lower light, growth may slow down, but it will still survive.
Soil
Philodendron Plowmanii prefers a well-draining potting mix rich in organic matter.
A mix with peat, perlite, and orchid bark works well, with a pH range of 5.5 to 7.0. Ensure the pot has drainage holes to prevent water accumulation.
Humidity
This plant enjoys high humidity levels of 60% or more.
To increase humidity, consider using a humidifier, placing a pebble tray with water under the pot, or grouping it with other plants. Signs of low humidity include browning leaf tips and leaf curling.
Temperature
Ideal temperatures range from 65°F to 80°F (18°C to 27°C).
Philodendron Plowmanii is hardy in USDA zones 10-11. It tolerates brief periods of cooler temperatures but should be protected from frost and extreme heat.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 during the growing season, every 4-6 weeks.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Philodendron Plowmanii in spring to maintain its shape and remove any dead or yellowing leaves.
Use clean, sharp pruning shears to avoid damage. Regularly check for any leggy growth and trim back as needed to encourage bushier growth.
Repotting
Repot every 1-2 years or when the roots outgrow the pot.
Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Choose a pot 1-2 inches larger in diameter and follow up with fresh potting mix. Water thoroughly after repotting.
Propagation
Propagation can be done through stem cuttings or division.
For stem cuttings, take a 4-6 inch cutting with at least one node, place it in water or moist soil, and keep it warm and humid until roots develop (about 4-6 weeks). Division is best done during repotting in spring when the plant is actively growing.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check soil moisture and adjust watering schedule. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Brown leaf tips
Why it happens
Low humidity or underwatering.
How to fix it
Increase humidity levels and ensure consistent watering, allowing the top inch of soil to dry out between waterings.
Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location with indirect sunlight to encourage bushier growth.
Root rot
Why it happens
Over-watering and poor drainage.
How to fix it
Ensure the pot has drainage holes, reduce watering frequency, and consider repotting into fresh, well-draining soil.
Pest infestations (e.g., spider mites, aphids)
Why it happens
Dry conditions or stress.
How to fix it
Regularly inspect the plant, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to grow actively. Fertilize every 4-6 weeks and consider repotting if needed.
Summer
During summer, ensure the plant receives bright, indirect light and maintain humidity levels. Water regularly, allowing the top inch of soil to dry out.
Fall
In fall, gradually reduce watering frequency as growth slows. Continue to fertilize every 6-8 weeks and monitor for pests as indoor conditions change.
Winter
In winter, water less frequently, about every 2-3 weeks. Keep the plant in a warm location away from drafts and ensure it receives adequate light.
Toxicity & Safety
Philodendron Plowmanii is toxic to pets (cats and dogs) and humans if ingested. The plant contains calcium oxalate crystals, which can cause irritation, swelling, and digestive issues. Symptoms may include mouth and throat irritation, vomiting, and difficulty swallowing.
