Water your plant thoroughly and allow the top 75% of the soil to dry before watering again. In low light, allow the soil to dry completely before watering. Water your plant less in the winter, when light levels are lower and growth has slowed.
Dracaenas should be fertilized with a water-soluble commercial houseplant fertilizer. Look for a fertilizer with a nitrogen-phosphorous-potassium ratio of 3:1:2 plus traces of zinc, sodium, manganese, copper and iron.
Your Dracaena Fragrans prefers medium to bright indirect sunlight but can survive in low light situations. Brown spots on the leaves or pale, bleached leaves usually indicate the plant is getting too much light. Leaves with less variegation, slow growth, and small new leaves indicate it is not getting enough light.
Temperature. The Ideal growth range is between 16°C - 24°C / 60°F - 75°F. No lower than 10°C / 50°F and avoid even light frosts at all costs.
To repot this plant, remove the loose soil around it, carefully lift the plant from its base, and place it in its new container, making sure not to damage its roots in the process. Then, fill the space around it with fresh potting soil, but don't pack it too tightly to ensure that the container maintains good drainage.
