Height: up to 90cm –120cm
Light: Place your plant in bright, indirect light. The more light it gets, the better the variegation will show, but keep it out of direct sun to prevent sunburn.
Water: Stromanthe likes to be kept barely moist at all times. Allow the top inch of the soil to dry out before watering again – but don’t let the soil get too dry. During the colder months, water carefully to avoid over-watering and eventual root rot.
Humidity: Stromanthe is a tropical plant and likes above-average humidity. Mist the plant regularly or place it on a pebble and water-filled dish, taking care that the pot does not touch the water. Placing in a humid-prone room, such as the bathroom or kitchen, can also help with its humidity needs.
Temperature: Average to warm temperatures of 13-26°C is ideal. Be sure to keep the plant out of cold or hot drafts.
Soil: Use quick-draining soil that retains moisture but still drains well. A peat-based potting soil is a good choice.
Fertilizer: Feed the plant every two weeks during the growing season, which is usually from early spring to end of autumn, with a balanced fertilizer diluted by half.
Repotting: Stromanthe houseplants do well in shallow containers. Only repot when you are sure the plant has outgrown its current pot and then in late spring or summer.
Pruning: Remove damaged leaves from the plant at the point where they are attached to the main stem, using pruning shears. Grooming can be done at any time of the year, although it is best done in spring before the plant enters its active growth stage.
Propagation: Division – in spring before the plant begins its growth spurt. Carefully separate the Stromanthe rhizome with 2 – 3 leaves attached from the main root ball. Plant the removed rhizome in a pot of moist potting soil. Enclose the entire plant in a plastic bag and keep it warm in medium light until new roots develop.
