Like most Philodendron, the Melanochrysum prefers well-draining media and to slightly dry between watering; to prevent "wet feet," allow the first several inches of the pot to completely dry before rewatering. It needs above-average household humidity, and always ensure plants are away from air vents and not placed in drafty areas. If inside, Philodendron can tolerate medium to medium-bright, indirect light; if outside, place in a semi-shaded area until fully acclimated to direct sun during warm and humid months. Always remember, the more light and warmth your Philodendron is getting, the more frequently you will have to water as the media will dry quicker. As new foliage emerges, the leaves will continue to expand in size until they harden off.
