The Philodendron Heartleaf can cope with low light conditions, but grows faster and produces more leaves bright indirect light. Do not put it in direct sunlight–the sun will burn the foliage.
Water your Philodendron when the top 50%-75% of the soil is dry. Water until liquid flows through the drainage hole at the bottom of the pot and discard any water that has accumulated in the saucer.
Basic household humidity is fine for this Philodendron, but higher humidity encourages larger leaves. Your plant will benefit from the occasional misting.
Your Philodendron Heartleaf will grow well in temperatures between 65-80 degrees during the day and above 55 degrees at night. Keep it away from drafts, especially during the winter months.
Feed once a month during spring and summer with a liquid fertilizer for indoor plants.
Philodendron leaves are toxic to pets and humans. Typically, ingestion will result in swelling of the lips and tongue, and stomach irritation with possible vomiting.
Trim out any dead, discolored, damaged, or diseased leaves and stems as they occur. Use clean, sharp scissors to avoid tearing or bruising the stems. Snip stems just above a leaf node. Wash the leaves frequently to prevent dust from clogging its pores. If you wish to propagate, take stem tip cuttings during the Spring or early Summer and place the stem in water or moist soil and they should root quite easily.
