Everything it needs
9 essentials at a glance
Watering
Dracaena Fragrans prefers to dry out slightly between waterings.
Water every 1-2 weeks, allowing the top 1-2 inches of soil to dry out before re-watering. In winter, reduce watering frequency to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf tips to brown and curl.
Light
This plant thrives in bright, indirect light but can tolerate low light conditions.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Avoid direct sunlight as it can scorch the leaves, but it can adapt to partial shade.
Soil
Dracaena Fragrans prefers a well-draining potting mix with a pH range of 6.0 to 6.5.
A mix of peat, perlite, and pine bark is ideal. Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.
Humidity
This plant enjoys moderate to high humidity levels, ideally between 40-60%.
To increase humidity, mist the leaves regularly, use a pebble tray with water, or place a humidifier nearby. Signs of low humidity include leaf tip browning and curling.
Temperature
Dracaena Fragrans thrives in temperatures between 65-80°F (18-27°C).
It is not frost-tolerant and prefers temperatures above 50°F (10°C). Ideal hardiness zones are 10-12, and it should be protected from drafts and sudden temperature changes.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season (spring and summer).
In fall and winter, reduce fertilization to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Dracaena Fragrans in spring to maintain its shape and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. For shaping, cut back the stems to the desired height, and deadhead any spent leaves to encourage new growth.
Repotting
Repot every 2-3 years or when the plant becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter. Carefully remove the plant from its pot, loosen the roots, and place it in fresh potting mix. Water thoroughly after repotting.
Propagation
Propagation can be done through stem cuttings or division.
For stem cuttings, take a 4-6 inch cutting with a few leaves, allow it to callous for a day, then place it in water or moist soil. Division can be done during repotting by separating the root ball into smaller sections. Best timing for propagation is in spring or early summer.

Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to promote new growth.
Summer
During summer, ensure the plant receives adequate light and humidity. Water more frequently as temperatures rise, and check for pests.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue fertilizing until late fall, then reduce frequency.
Winter
In winter, water less frequently, allowing the soil to dry out more between waterings. Keep the plant in a warm location away from drafts.
Toxicity & Safety
Dracaena Fragrans is mildly toxic to pets, particularly cats and dogs. Ingestion of the leaves can cause vomiting, lack of appetite, and excessive salivation. It is also mildly toxic to humans, causing gastrointestinal upset if ingested.
