Propagating Dracaena marginata bicolor

Cuttings is by far the simplest manner of reproducing your favorite Dracaena marginata bicolor.

Propagate Dracaena marginata bicolor through stem cuttings

  • select the “branch” you’re going to “sacrifice” for this. Usually, a cutting is about one foot (30 cm) long. However, you can shorten it to as little as 3 inches (7.5 cm) or make it as long as you wish.
  • The mother Dracaena marginata bicolor will grow new leaves from nodes near the tip of the cut. It’ll branch out nicely.
  • Place the cutting in a glass of water, leafy head upwards. Ensure the stem is immersed by about 2-3 inches (5-8 cm).
  • If you’ve cut more than one cutting from the stem, mark the “top” of each leafless stem with a piece of yarn or a ribbon.
  • Roots will sprout from nodes in the immersed area, while leaves will start sprouting from nodes near the tip.
  • When roots reach an inch (2.5 cm) in length, the cutting can be transferred to a pot with fresh, clean soil mix.

Making cuttings and cutting the top off your dracaena is the surest way to replicate your Dracaena marginata bicolor with the exact same properties as the mother plant. In effect, it is a form of cloning.

Common diseases on Dracaena marginata bicolor

The most important problem that Dracaena plants face is almost always overwatering.

If you’re prone to visiting your plants with water daily, here’s a simple trick. It deals with overwatering (which causes yellow leaves) and insufficient air moisture.

  • Switch the water saucer of your Dracaena marginata ‘bicolor’ pot out for a tray with clay pebbles. Rest the pot atop it.
  • Water the pot itself only once a week. Satisfy the urge to water on other days by dousing water on the clay pebbles.
  • The water will evaporate, creating air moisture that is perfect for your Dracaena marginata, without drowning it.
