Anthurium Cobra is an easy and fast-growing plant once it is established and has recovered from any shipping stress. We recommend fertilizing this plant every month during spring and summer with a diluted general houseplant fertilizer. It is tolerant of normal household humidity but may appreciate higher levels provided by misting or a humidifier. It can be pruned back to give it a fuller look. All cuttings are easily propagated because of the already established aerial roots. They can be water propagated or planted directly into the soil.
