Dracaena Rikki is a cultivar of the Dracaena family known for its long, sword-like green leaves with bold yellow or light green stripes. It’s a relatively low-maintenance indoor plant, popular for its air-purifying properties and tolerance to lower light conditions.
In Toronto’s environment, the care guidelines for Dracaena Rikki are as follows:

Light:
It prefers bright, indirect light but can also grow in medium light conditions. Avoid prolonged exposure to direct sunlight, as it may scorch the leaves. During Toronto’s winter months, when daylight hours are shorter, it’s recommended to place the plant near a window to meet its light requirements.

Temperature:
Dracaena Rikki thrives in warm temperatures between 18°C and 24°C. Temperatures below 10°C may cause damage. In the winter, avoid placing the plant near cold windows or air vents.

Watering:
In spring and summer, keep the soil slightly moist but avoid waterlogging. In fall and winter, you can reduce watering and wait for the top of the soil to dry before watering again. Since Toronto tap water may contain high levels of fluoride, and Dracaenas are sensitive to fluoride, it’s recommended to use filtered water or water that has been left out for 24 hours.

Humidity:
It doesn't have high humidity requirements but grows better in slightly humid environments. Indoor heating in the winter can lower humidity, so consider using a humidifier or placing a tray of water near the plant to increase moisture.

Soil and Fertilizing:
Use well-draining potting soil. Fertilize once a month with a balanced general fertilizer. A nitrogen-phosphorus-potassium ratio of 20-20-20 or 10-15-10 is recommended.

Pruning:
If the leaf tips turn yellow or brown, trim them to keep the plant tidy and healthy.
