While the intention of this blog post is to bestow all the earthly wisdom of Dracaena houseplants upon you, it is important to note that Dracaena is a family of approximately 120 species. This family tree is large and vast.
Many of us know some of these plants by their colloquial names like "corn plants", "Janet Craig" or "song of India". They tend to grow very large and don't mind being trimmed from the top for you to maintain some control. If you prefer to get real fancy, you can propagate the cuttings.
Most species of dracaena prefer bright light. However, there are a few anomalies (as in every family) that enjoy the shade. D. Fragrans and D. Massangeana are a few outliers that thrive in a bit of darkness. Direct sunlight can damage the leaves of any dracaena so it is important that they receive indirect sunlight.
Thorough watering is required, just not often. A pro-tip I like to use at home on my corn plant is to water from the bottom up. The soil will drink the water at its own pace. If you use this method, be sure to check the drain tray after a few hours. Any Excess water must be poured out. DO NOT leave excess water sitting in the drainage portion of your planter. That is a wonderful way to over water and rot a plant.
They do not like to be cold. Think of these like your southern relatives that could not survive a New England winter. Keep them away from anywhere a cool draft could come in such as windows or doors. They prefer temperatures over 65 degrees.
Humidity does them well. When your heat is running, run a humidifier from time to time. Its good for you and your plants.
Dracaena can add a dramatic flair to any space and you'll absolutely love having them.
