Dracaena marginata, also known as the Madagascar Dragon Tree, is a popular houseplant known for its thin, spiky leaves and striking silhouette. Here's a guide to Dracaena marginata care:

1. Light: Dracaena marginata prefers bright, indirect light. It can tolerate lower light conditions, but too little light can cause the plant to grow slowly and lose its vibrant color. Avoid direct sunlight, as it can scorch the leaves.

2. Watering: Water your Dracaena marginata only when the top inch of soil is dry. Overwatering can cause root rot, so be sure to allow excess water to drain away. In the winter months, you can reduce watering to once every two weeks.

3. Soil: Dracaena marginata prefers well-draining soil that is rich in organic matter. A mixture of peat moss, perlite, and vermiculite can work well. Be sure to repot the plant every few years to prevent the soil from becoming compacted.

4. Humidity: Dracaena marginata prefers moderate to high humidity. You can increase the humidity around the plant by misting it regularly or placing a humidifier nearby.

5. Temperature: Dracaena marginata prefers temperatures between 60°F and 75°F. Avoid placing the plant near cold drafts or heat sources like radiators.

6. Fertilizer: Feed your Dracaena marginata with a balanced fertilizer every two to three months during the growing season. Be sure to follow the manufacturer's instructions and avoid overfertilizing.

7. Pruning: Prune your Dracaena marginata to remove any yellow or brown leaves. You can also prune the top of the plant to encourage branching and a fuller shape.

In summary, Dracaena marginata is a hardy and low-maintenance houseplant that prefers bright, indirect light, well-draining soil, and moderate to high humidity. By following these care guidelines and monitoring your plant regularly, you can help your Dracaena marginata thrive and add a touch of natural beauty to your home.
