Dracaena Marginata (Madagascar Dragon Tree)

About the Dragon Tree

The Madagascar Dragon Tree or Dracaena Marginata is just one of the many beautiful houseplants belonging to the Dracaena Group.

Photo of a mature Dragon Tree in a small white pot being grown as a houseplantThe common name "Madagascar Dragon Tree" is a combination of its native origin, "Madagascar" and its famous cousin Dracaena Draco (meaning Dragon). A plant that's well known for its tendency to ooze a red blood like resin when cut or damaged, giving it an "alive" quality.

There is also an old legend that once a hundred-headed dragon was killed and where it's red blood flowed, hundreds of Trees grew which locals at the time called Dragon Tree's.

Before you go cutting your Dragon Tree looking for this mysterious blood, only D. Draco has the red resin whereas the common houseplant D. Marginata doesn't.

Like the rest of the Dracaena varieties grown indoors, this houseplant has many advantages that make it fantastic to have around. The first selling point is that it's still super popular today, even though it's been living in homes and workplaces since the 1960's it's escaped that dreaded "old fashioned" label.

The growth pattern is also an advantage because D. Marginata tends to remain quite slender and tall even after many years of growth and still looks great even when it's reaching its maximum indoor height. The stems are stiff and sturdy so it can also fully support itself without any help from you.

Arguably this is one of the cheapest houseplants to buy and easiest to look after. Another perk is that the Dragon Tree will cleans the air and is especially adapt at filtering out xylene and trichloroethylene.

Finally it also gives you a reasonable variety to choose from in terms of looks. It comes in four main cultivars and varieties, which are as follows.

D. marginata

The original Dragon tree. The leaves have a narrow red purple like banding along the edges, with the central parts being a darker green (top picture).

D. marginata 'tricolor'

Tricolor is the same as the original Marginata except it has three colours in its leaves. A band of yellow separates the light green from the edged red stripes, producing an overall greenish-gold effect (middle picture).

D. marginata 'colorama'

This is the most modern cultivar, with the same growth pattern as the original (although perhaps a little slower) with the difference between the two being seen once more in the leaves. It mirrors the tricolor with the three colours on the leaves, except the red bands on the outside edges are much more prominent, creating an overall reddish or pinkish look (bottom picture).

D. marginata 'tarzan'

Unlike the previous three, D. marginata 'tarzan' easily stands out as being quite different from the rest.

Tthe leaves are the same colour as the original D. Marginata but they're quite a bit tougher, wider and slightly thicker. At the very top of each stem or cane, the leaves are laid out by the plant in an almost spiky ball shape (to us they look like the end of a Dragon's tail!).

A large Dracaena marginata 'tarzan'New leaves emerge from the crown and initially point upwards. As they grow and are gradually replaced by newer leaves, the older leaves start pointing sideways, before reaching full maturity and finishing off by pointing downwards. These downward facing leaves then yellow up and drop off, in this way the canes get longer and longer and the "balls" are able to "travel" upwards.

While it's a unique and interesting looking houseplant, 'tarzan' unfortunately tends to be more expensive to buy which has negatively impacted its availability in shops. So if you like this variety then be prepared to spend some time searching for it.

Whichever variety or cultivar you have, the care requirements are the same and we're going to go over these now for you.

Dragon Plant Care Guide

Light

Light shade is best for your Dragon Tree plant. Sitting on a North facing window ledge, close to an East / West facing window or some distance away from a South facing one are all good locations. The leaves will scorch if it's too bright, and if it's too dark newer leaves will be small and limp looking.

Watering

Try to keep the soil moist (but never soggy or wet). A little dryness at the roots is better than risking overwatering. Make sure you cut back the watering in Winter as this is the prime time for plants to get the dreaded mushy soft stems.

Humidity

Reasonable humidity is required. Often the humidity in the average home is perfect, but if you can, mist the leaves from time to time especially if the air is quite dry. The misting will also help remove any dust settling on the leaves.

To get new leaves sprouting on a regular basis you'll need to feed your Dragon Tree

Feeding

To get new leaves sprouting on a regular basis you'll need to feed your Dragon Tree. Try and do it monthly in Spring and Summer. Sparsely in Autumn / Fall and none in Winter.

Temperature

This plant does not like the cold. The room it lives in should never have temperatures lower than 10°C / 50°F. If you've put your plant outside for the Summer you must remember to bring it back indoors before any sign of frost. The temperature range for ideal growth is between 16°C - 24°C / 60°F - 75°F.

Repotting

You only need to repot when the roots are are very congested and the plant is obviously suffering as a consequence. Unfortunately the roots of the Dragon Tree grow exceptionally fast so if you follow this definition exactly, you may end up repotting twice a year! Instead we would advising being a little cruel and only repotting every two years at most.

These plants can do really well with very little root room. Take a look at the first picture in the article and in the gallery where you can see how big the plant is, even though it's in a small pot.

The roots of a Madagascar Dragon Tree which has outgrown its potIn our experience Dragon Trees aren't fussy about the potting mix you choose to grow it in. Just make sure it's fresh and not too heavy. We wrote an article about different Growing Mediums if you want to learn more about this topic.

On occasion you may find the large tap roots start to "coil" around and around the pot causing the root ball to rise up out of the container. If this happens, take the plant out of the pot and cut back some of the large thick tap roots before positioning what's left back in the pot which should remove the "coil" effect.

Propagation

There are three main ways to propagate a Dragon Tree and typically you can do all three methods at once to create multiple plants.

Propagation works best on an older plant because in time the canes will become longer or "leggy" as the leaf area shifts higher and higher up the plant. This gives you a lot of propagation material, which means you can:

  1. Simply remove the crown and the top inch of stem and pot it up in potting compost to start a new plant.

    Use a rooting hormone and to increase your chances of it working, keep the cutting warm by providing bottom heat.

    • Tip - If you can't provide bottom heat, only attempt this in Summer where it will be easier to keep it warm naturally.
  2. Once the crown has been removed you can cut the remaining cane back to about half the original length (or more or less depending on what you're trying to achieve visually).

    New growths should then form at the cut edge within a couple of months.

    You can either leave the new growths on the existing stem as they are, or remove them after they're big enough and carry out "One" again to create more plants.

    • Tip - Because several new growths can form at the cut, you can create a multi caned plant. Look at the bottom three pictures in our photo gallery above to see how this looks in practice.
  3. Assuming you've done both things above, you'll now have a left over piece of stem / cane. This can be cut into bits around 3 inches long and used to create a "Ti Tree".

    To do this, allow the stem / cane to dry for a day before sticking the pieces straight up in potting compost or a small container filled with water.

    If planted in soil keep warm and moist. If you're trying to root in water, when a reasonable number of roots have appeared plant up in potting compost.

    • Tip - The pieces of stem / cane need to face "up" in the direction they were growing when part of the parent plant, so you may want to mark the cutting with an arrow before you get started to avoid confusion later.

Speed of Growth

Dragon Trees are quite slow growing compared to other houseplants, however in Spring and early Summer they'll have fast spurts of growth at the crown which you'll definitely notice.



The final height of your Dragon Tree depends on how tall your ceiling is!

Height / Spread

The final height of your plant depends on how tall your ceiling is! To be fair, while natively they can reach 3m / 10ft or more, indoors you will probably run out of large enough pots to allow the plant to reach that size. So expect yours to only reach 2m / 6ft after many (many) years. No wider than 1m / 3ft.

Flowers

Dragon Tree flowers are very rare and almost never seen on indoor plants. This is a houseplant grown for its foliage and architectural looks only.

Are Dragon Trees Poisonous?

The sap found within the leaves and stems do have small levels of a toxic substance that, while unlikely to be fatal, can cause irritation in people and pets when ingested.

Anything else?

If you've followed all the Dragon Tree propagation methods to increase your chances of getting at least one viable new plant, you could get lucky and end up with too many! Rather than throw them away, source a nice pot and give them away to friends and family.

Dragon Tree Problems

New Dragon Tree leaves are very small

Almost certainly too little light. A Dragon Tree won't give any thanks if you give it low light conditions over a long period of time.

Dragon Tree leaves falling off

If happening slowly over a number of weeks then this isn't a sign your Dragon Tree is dying, in fact it's showing you're treating it well!

The lower leaves of a Madagascar Dragon Tree yellow and fall off as they grow olderAll Dracaenas are False Palms with a crown of leaves sitting at the top of their stems, new growth forms at the very tips of these stems, and the older leaves at the bottom of the crown will gradually yellow and fall.

This happens quite often, and can be a bit shocking if it's the first time your plant has done it. But providing new leaves are forming too it's perfectly normal.

Leaves going yellow and falling off very quickly

As with the problem above, yellowing and falling leaves aren't usually an issue. However if you're very concerned, have a feel of the stems. If they're firm then it's very likely you've nothing to worry about. If the stems are very soft or squishy then read on to the next problem.

Soggy Soft Cane / Stem

This has been caused either by giving far too much water over a prolonged period, or from being exposed to very cold temperatures. If this happens then your Dragon Tree is probably already dead and can't be saved in its present form. If any parts of the stem feel firm, or the leaf crown is intact you could try and propagate a replacement plant.

Leaves with brown spots

Usually a sign of underwatering. Try to keep the soil moist much of the time. If you would call the the marks more like "blotches" than spots, it's caused by overwatering.

Leaves have brown tips and yellow edges

Often this is a symptom of dry air or cold draughts blowing near your plant.

Bleached dry leaves

Scorched leaves caused by too much light.

Mealybugs / Red Spider Mite

Mealybugs need to be treated with something like a cotton wool bud soaked in methylated spirit. Gently rub over the insects with the soaked cotton wool bud to remove them.

Red Spider Mite can be treated with an insecticide or if you'd prefer not to use chemicals, you can consider increasing the humidity for a few weeks or so, i.e. by daily misting.
