Plant FAQs: Cordyline Red Sister

How to care for Cordyline Red Sister?  

Here’s a guide on how to care for your Cordyline Red Sister, also known as the Hawaiian Ti plant, and keep its vibrant red foliage thriving:

Light:

• Cordyline Red Sister prefers bright, indirect sunlight. This will promote healthy growth and maintain the rich red color of the leaves.
• Avoid strong direct sunlight, especially during the hottest parts of the day, as it can scorch the leaves. Lower light can be tolerated, but the red color might be less intense and the plant might grow leggy.

Watering:

• Water regularly, keeping the soil consistently moist but not soggy. Overwatering is a major threat to Cordyline Red Sister.
  • Here’s how to check moisture: Stick your finger into the top inch of soil. If it feels dry to the touch, it’s time to water.
  • Allow the top inch of soil to dry out slightly between waterings.

Soil and Drainage:

• Well-draining soil is essential. A good quality potting mix or a mixture of potting soil with added perlite or sand works well.
  • Ensure your pot has drainage holes to prevent waterlogging.

Fertilizing:

• Fertilize sparingly during the growing season (spring and summer) only. Apply a balanced liquid fertilizer diluted to half strength once a month or a slow-release fertilizer formulated for houseplants according to package instructions.
  • Avoid overfertilizing, as it can damage the roots.

Temperature and Humidity:

• Warm temperatures between 60-80 degrees Fahrenheit (15-27 degrees Celsius) are ideal. Protect your plant from cold drafts and sudden temperature fluctuations.
• Moderate humidity is beneficial. While Cordyline Red Sister is not as fussy about humidity as some houseplants, dry air can cause brown, crispy leaf edges.
  • You can increase humidity by:
    • Misting the plant occasionally with lukewarm water (avoiding the center of new growth)
    • Using a pebble tray filled with water (ensure the pot sits above the water level)
    • Grouping your Cordyline Red Sister with other humidity-loving plants
    • Using a humidifier

Additional Tips:

• Wipe the leaves occasionally with a damp cloth to remove dust and improve light absorption. Avoid harsh chemicals or cleaning products.
• Cordyline Red Sister is a relatively slow grower. Don’t be discouraged if it doesn’t put out new leaves frequently.
• Watch out for common houseplant pests like mealybugs and spider mites. Neem oil solution or insecticidal soap can be used for control if needed.
• Cordyline Red Sister can mature to 8-10 feet tall outdoors in tropical climates. As a houseplant, it may reach 3-4 feet and can be pruned to maintain a desired size. Use sharp, sterilized pruning shears.
