Ideally, Cordyline should be kept in bright locations (like a window sill) with exposure to indirect sunlight from the east. The plant should not be kept in full direct sunlight as this can cause its leaves to burn.
The Cordyline's soil should be kept slightly damp, not soggy, and the top inch should be allowed to dry out before the plant is watered again. Let the soil dry out completely before watering it again. Don’t let any water stand in the saucer or overwater the plant as this can cause root rot. In the winter, you can increase the gaps between waterings and let the soil dry out a bit more.
Although it can grow in low humidity, it does best in environments with high humidity. Lightly mist the leaves on a regular basis or use a pebble tray to ensure the plant has enough humidity.
Cordyline do best between 65-75 degrees Fahrenheit, you should place them in spots that don’t face drafts or cross winds and avoid rapid temperature changes. Try to avoid allowing the temperature to drop below 62 degrees Fahrenheit.
They do best with general houseplant / indoor plant fertilizers; they should be fed once a month during spring and summer time.
They can be toxic to pets and humans – if consumed, they can cause some irritation in the mouth and stomach, and potentially nausea and/or vomiting.
