Philodendron Selloum “Green Princess”: How to Grow Care Tips

Please identify my plant and tell me how to care for it.

Hi Denise,

Your plant is called a Philodendron Selloum “Green Princess.” It is a new philodendron hybrid that is becoming very popular. The care is quite easy.

 

WaterUnlike other philodendrons, this plant likes likes moist but not soggy soil. During the winter, water less often, keeping the soil barely moist. Be sure there are drip holes in the bottom of the pot so excess water can escape and never allow the plant to sit in water.
Plant Food: Feed monthly during the spring, summer, and fall with a water-soluble balanced  plant food diluted to ½ the recommended strength. Too much plant food causes excess salt build up in the soil and can result in leaf burn. The leaves on a philodendron usually turn pale green when the plant needs more fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small..
Temperature: Philodendron Selloum “Green Princess” likes warm temperatures above 55°F(12.8°C). Keep these plants away from drafts, air conditioners, and open doors especially during the winter.
Humidity: The “GreenPrincess” requires a more humid environment to grow well. If your home is very dry in the winter, place your plant near a humidifier or sit it on a wet pebble tray. Be sure the plant is on the stones and not in the water.
Soil: Grows best in a rich, slightly alkaline soil that retains moisture. The leaf tips burn if there is too much salt in the soil usually usually caused over-feeding or using water that has passed through a softener
Pot Size: When the roots have filled the existing pot, it’s time to move your philodendron to a larger pot  The new container should only be 1″-2″ wider and deeper than the previous container.
Toxicity: All philodendron plants are very poisonousPlants are a great addition to homes and offices, but it’s important to know whether your plants are dangerous to children, pets, or even adults. Some plants contain chemicals such as oxalates, solanine, glycosides, or alkaloid lycorine that may cause vomiting, nausea, diarrhea, swelling and redness of the mouth, throat, and lips, and trouble breathing. Touching parts of certain plants, especially the sap, may cause various skin irritations. The weight and age of the human or pet involved, and the part and amount of plant eaten determine how severe the reaction to the toxins will be. Although plants may be listed as non-toxic, they can still cause individual allergic reactions. If there is any question after a houseplant has been ingested or touched, immediately call the Poison Control Center 1-800-222-1222.  More poisonous houseplant information and pictures of common plants that are dangerous to children and pets can be found in my book Don’t Feed Me to Your Cat: A Guide to Poisonous Houseplants because they contain calcium oxalate crystals. Eating any part of the plant may cause the following symptoms: pain in the mouth, drooling (dogs & cats), and vomiting. If swelling of the lips, tongue, and airway occurs, it becomes difficult to breathe or swallow.
