Dracaena is a genus of plants that includes about 40 species, including Dracaena marginatas, of which magentas are a common variety. Magenta plants are evergreen trees or shrubs native to the tropics and are similar in appearance to palms. They are commonly grown as houseplants, and with their variegated leaves and reddish edging, can add an exotic style to your home.
Maintain room temperature above 15.6 degrees Celsius -- between 21.1 to 26.7 degrees Celsius is ideal. Never allow temperatures to dip below 2.78 degrees Celsius or exceed 32.2 degrees Celsius. Dracaenas prefer mostly shady conditions. If the leaves begin to yellow, reduce exposure to direct light.
Keep the soil moist from spring until fall. Water thoroughly so the water drains out the bottom of the pot. Reduce watering during the winter, allowing the soil to dry out between waterings.
Mist leaves two or three times a week, especially if the plant is near a heat source or near a draft where drier air is more likely. Ideal humidity levels for Dracaena plants are between 60 and 100 per cent relative humidity.
Fertilise monthly with a houseplant fertiliser that has an nitogen-phosphorous-potassium ratio (N-P-K) of 3:1:2 or 3:1:3. Follow the dosing instructions on the label based on the size of your plant and exact fertiliser used.
Treat disease and pests immediately. Take a sample of a damaged leaf to a nursery or cooperative extension office for diagnosis and treat as recommended. For example, if your Dracaena magenta plants are pale and have green transverse veins, it may be a magnesium deficiency, which should be treated with a manganese chelate spray.
