Philodendron Emerald Prince – How to Grow Care Guide

Bought this recently from Trader Joes without any name or care instructions. Looks like it could be from the upright Philodendren family but we need your expertise. Thank you in advance for your help.



Hi Anne,

Your plant is a type of Philodendron, but, from your picture, it’s a little difficult to tell whether it’s an Imperial Green Philodendron, a Philodendron Emerald Green, or a Philodendron  Emerald Prince. I think it’s probably an Emerald Prince like the picture below. The good news is that the care tips for all three varieties are the same.

Light: This plant can live in low lightWhen you select “Low Light” a list of the most adaptive plants in our database appears. These plants can live in lighting conditions too low to support any other plants in our database, but will grow faster in medium and high light. Variegation (color) in the leaves is often lost in low light. A plant in low light needs less water and fertilizer than the same plant in better light. Place a low-light plant within 2-3 ft. of a window with a northern exposure, 3-5 ft. of a window with an eastern exposure, 4-10 ft. of a window with a western exposure, and 10-18ft. of a window with a southern exposure. A low light area has between 50-150 ft. candles of light. The best low light house plants are: Chinese Evergreen, Dracaena Janet Craig, Peace Lily, Heart leaf Philodendron., but it grows much faster in medium light.

Water: I recommend allowing the top 50% of the soil to dry out before you water. Water less, allowing the soil to dry out a bit more, during the winter months. It’s easy to save an underwater plant, but an over watered plants develops root rot and quickly dies.

Plant Food: Feed monthly when the plant is actively growing with a balanced 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. diluted to ½ the recommended strength. If your philodendron is not producing new leaves, it doesn’t need any plant food; this is especially true in the fall and winter.

Temperature: Philodendron plants like warm temperatures. They grow well when the temperature is  70°-85°F ( 21.1°-29.4°C)

Soil: Use a rich, quick draining soil. If your potting soil appears heavy,  you may have to add a little sand to loosen it up.

Pot Size: Philodendrons like to be slightly root-bound and a little snug in their pot. When the roots have just about filled the container, move your plant to a new container that is only a few inches larger than the existing one. Do not use a pot that is too large. When the pot is too large, the soil stays wet too long and the roots rot. Be sure there are drip holes in the bottom of the pot so excess water can escape. The best time to re-pot a philodendron is in the late winter or early spring before the plant starts to grow again after a winter rest.

Toxicity: All philodendrons contain calcium oxalate 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 plants. Please keep hem away from small children and pets.
