Dracaena, commonly referred to as Corn Plant or Dragon Tree, is a captivating genus of tropical and subtropical plants renowned for their striking foliage. The genus includes around 120 species, each boasting unique leaf shapes, sizes, and colors. Dracaena plants are prized for their ornamental value and are popular both as houseplants and garden specimens.
Adapts well to a wide range of indoor light conditions — from bright indirect light near a window to moderate shade. Variegated forms (e.g. Dracaena marginata, D. fragrans 'Massangeana') retain better colour and markings in brighter light. Avoid harsh direct midday sun.
Allow the top half of the soil to dry out between waterings. Dracaena prefers moderate, consistent moisture — not the drought cycle of succulents, but never kept wet. Reduce watering in winter. Critically: use only fluoride-free water (rainwater, distilled or filtered). Fluoride in tap water causes the characteristic brown leaf tips seen on almost all indoor Dracaenas.
Use a well-draining potting mix with added perlite. Slightly acidic pH (6.0–6.5). Avoid phosphate-heavy fertilizers, which can make fluoride toxicity worse.
Optimal range 18–27 °C; minimum 12 °C. Sensitive to cold drafts and temperature fluctuations. Standard indoor humidity is adequate, but placing the plant away from radiators and heating vents prevents leaf tip browning.
Feed monthly in spring and summer with a balanced, low-fluoride liquid fertilizer at half strength. Do not feed in autumn or winter. Excess fertilizer salts accumulate and worsen fluoride toxicity symptoms.
Trim brown leaf tips with scissors, cutting at an angle to mimic the natural leaf shape. Remove entirely any leaves that are more than 50% brown. Prune canes back to the desired height in spring — new growth sprouts from just below the cut. ⚠️ Toxic to cats and dogs (saponins): keep away from pets.
The most common method for propagating Dracaena is by stem cuttings. This involves cutting a healthy stem section and allowing it to root in water or soil.
Another method for propagating Dracaena is air layering, which involves rooting a stem while it is still attached to the parent plant.
