How to take care of Dracaena Marginata. Also called the Madagascar dragon tree. It is considered an indoor plant because it cannot endure outdoor temperatures below 32 degrees f.
It is a slow grower and drought tolerant. However, around the American southwest where temperatures can get above 110 degrees f. in mid-summer you should water 2-3 times per week unless you have your refrigerated air on day and night. If so, water only once or twice per week.
There are numerous varieties including wider leaves and thicker trunks, but this post is about the thin long Marginata plants. These plants are usually on display at most local garden nurseries and many American Southwest-type homes.
The most common is the one with long slender dark green leaves. They can take low to lots of light. So, placing them on the south or west-facing window is a good spot.
What kind of Soil and Fertilizer Should you use?
From my experience, the soil likes to be slightly dried before watering. Typically, about 2-3 times per week works best. Use good loamy potting soil when repotting or going to a larger pot. It only needs occasional fertilizer once in spring, summer, and fall will suffice. Use a good all-purpose fertilizer and an analysis of 20-20-20 will work.
You can grow and use this plant during the winter seasons, but it needs to be placed indoors. Anything below 32 degrees F. the plant will die on you. It is also a good idea to keep them away from the door entrance or exits because the cold draft will affect the plant.

The Variegated Dracaena
What does Variegated mean? It’s simple, it means more than two colors on the leaf or blade. It is derived from the Latin word “Variegatus”. This can apply to any plant, tree, shrub, or indoor plant with at least two or numerous colors on its leaves.

Can I Plant Outdoors?
If you live in regions where it rarely freezes you can plant the larger one in the ground outdoors. They will add that tropical look to almost any landscape. Be careful not to over-water it as it will develop root rot quickly.

Problems with Dracaena Marginata
They are susceptible to mealybugs, not enough humidity, and over-watering. At the first sign of mealybugs spray with organic neem oil or insecticidal soaps. If the plant is saturated with mealybugs, it is best to toss the plant in the trash bin. Be sure to cover with a plastic or paper bag to ensure these bugs do not get a chance to infiltrate other plants nearby.
Your leaves will fall quickly when the plant is overwatered. Let the plant dry out completely before watering again.
