Th Dracaena fragrans, also known as the Corn Plant, is a popular indoor plant for more than gardeners.

In fact, the plant has wonderful ‘cleansing’ properties, able to remove toxins from the air, increase humidity and levels of cognitive function!

It’s beautifully variegated leaves and compact size make it a favorite in many office parks and homes, but before planting or growing a Dracena fragrans, there are some things to consider and dangers to avoid

This complete guide explains how to grow corn plants indoors from cuttings and seeds, as well as how to avoid the dangers to your pets, so that you can reap the benefits this lovely and graceful plant provides.

Growing Zones for Dracaena fragrans: Where To Grow Corn Plant

The Corn Plant doesn’t enjoy the cold and grows best in hardiness zones 10 – 11 with temperatures of 60°-75° F as experienced in its native environment.

So, if you live in zones where it won’t survive outdoors during certain seasons, consider choosing a sunny indoor location and mobile planting.

Maintaining it above 55° will be sufficient for the plant to do well and stay healthy. Anything less for a significant amount of time will see the long, bushy leaves losing color and vitality.

Adequate exposure to lighting is also crucial to the plant’s survival. An indoor Dracaena fragrans abhors direct sunlight as broad leaves can become singed,³ yet conversely too little light will cause the leaves to become narrower in an effort to conserve energy.

Therefore a medium level of radiance and indirect sunlight would be required where the light is filtered and not too bright, preferably in a hanging basket or a high shelf for safety reasons to keep leaves out of the reach of curious cats.

Best Growing Conditions for Dracaena fragrans (Dracaena fragrans Growing Zone)

If the humidity and the intensity of sunlight exposure have been perfected, the next requirement is for the soil composition.

When growing it outside in a shaded area, the soil has to be able to drain away excess water as the roots will not do well resting in very sodden dirt.

For indoor planting, as long as a potting soil is used and there a sufficient draining holes in the base of the container,⁶ there will be no threat of root rotting problems arising. A watering regime to keep the soil moist during the early stages of the growing season should be employed along with the application of a liquid fertilizer, and then a reduced frequency of both in the fall.

The Dracaena fragrans are drought tolerant but still need a little TLC.

Growing Dracaena fragrans From a Seed (Planting Tips for Dracaena fragrans or Corn Plant)

The germination process for Dracaena fragrans starts with a handful of seeds and a bowl of water at room temperature. The reason for immersing the seeds in water for up to 5 days is to mimic the harshness of their native habitat where nature naturally breaks down the defenses of the seed so that it will germinate faster.

Water immersion tricks the seeds into believing that there is more than enough moisture for them to begin their growth cycle. This also overcomes an inbuilt inhibitor mechanism that prevents germination when the seeds are exposed to small amounts of moisture, like when it is inside a fruit.

After 5 days it’s time to take the next steps

• Fill a small pot with a starting soil mixture and gently push the seeds below the surface
• Moisten the soil but avoid overwatering by ensuring that the pot has drainage holes
• Place a plastic cover over the pot to simulate a tropical environment
• But if the ambient temperature is below 60° place the pot on a germination mat or under grow lights
• Position in indirect sunlight
• Water so the soil becomes moist, and poke a few holes in the plastic to prevent the excess build-up of too much moisture
• As soon as the seeds germinate the plastic can be removed
• Separate the seedlings when two ‘true leaves’ have appeared then individually place them into larger pots with normal potting soil. These two leaves are able to perform photosynthesis, while seed leaves, ‘cotyledons’, are not so it’s important to wait for them to appear
• Apply a water-soluble fertilizer every now and then to ensure sufficient nutrient availability

Top Tips for Growing a Dracaena fragrans From a Cutting (Air Layering and Rooting in Water)

Implementing just a few of these tips when learning how to propagate Dracaena fragrans Plants will simplify the steps needed to grow these houseplants from cuttings or seedlings.⁸

From a cutting

• Sterilize the scissors or shears about to be used in alcohol
• Choose a suitable rooting hormone. But don’t apply too much as this can cause harm to the plant so follow the instructions closely
• Air layering is where the underside of a branch is partially cut, smeared with sphagnum moss, and wrapped in plastic while still attached. Maintain moisture in the area and within 1-3 months roots will sprout from this open wound
• Sever the branch below this area and then place your cutting root down in a container with some potting mix

Rooting in water is another method of Corn Plant propagation that is preferred by some as the roots can easily be seen as they sprout into existence

• Completely snip off a branch below the leaf node, leaving at least two leaves still attached
• Smear the cut end with a rooting hormone
• Remove any lower leaves and submerge those now exposed nodes in a jar of water
• Place in a location bathed in indirect sunlight
• It can take between 2-8 weeks for the roots to develop but the good point with this propagation technique is that you can see everything
• Once they are ready, transplant them into a pot filled with a porous potting soil

Top Tips for Growing a Dracaena fragrans From a Seedling (Corn Plant)

Transplanting a seedling from one container to another is a delicate process and needs to be undertaken carefully to avoid stressing the Dracaena fragrans Plant. This phenomenon is called transplant shock and can lead to health issues or even to the plant dying.

Whenever repotting one of these low-maintenance evergreen shrubs,⁵ follow these steps so as not to cause undue stress

• Before transplanting, ensure the plant is sufficiently watered
• Be careful not to cause any bruising to the roots when extracting from the smaller pot
• Conduct the extraction either in the morning or the evening when it is cooler than during the middle of the day
• Mix organic fertilizer or compost into the new soil which needs to be aerated
• Do not bury the seedlings too deep but allow enough side room for lateral growth
• If transplanting outside, remove all weeds and scatter mulch around the base
• Water thoroughly

Watering Needs for Dracaena fragrans Plants & How Much Sunlight Does Dracaena fragrans Need Each Day?

Dracaena fragrans are hardy plants and only require between 2-4 hours of bright but indirect sunlight a day. Their watering needs are equally not very demanding.

As long as the soil is moist there are no problems. Generally, a once-a-week watering regime is fine, or just watering when the topsoil is dry to a depth of 2-3 cm.

In the winter months, less watering will be required as more moisture will be retained in the soil.

Types of Dracaena Plants – How To Identify Dracaena fragrans (Corn Plant)

Many of the different types of Dracaena fragrans. Plants are easily discernible from one another by the yellow markings and the shapes of the leaves. Some of them, like the Dracaena marginata ‘Colorama’ is actually reddish.

Despite the fact that there millions of leaves in the world, the Dracaena fragrant Plants are instantly recognizable from theirs, whether they are thin, wide, with a thick yellow stripe running down the center, or if the outer edges are lined with gold.

When grown indoors they rarely bear fruits or bloom with flowers. In an outdoor setting, the fruits burst forth in colors of orange and red, small and round, and temptingly tasty.

Just like with consuming the leaves, the fruits are poisonous for most animals so are avoided. Each fruit has between 1-4 seeds and, even though the Corn Plant can perform self-pollination, insects also assist in the pollination process.

It is this lack of insect pollination that restricts the fruits from emerging indoors, but flowers can be coaxed to bloom on demand, but it may not be a good idea.

With the correct lighting, constant temperatures, and nutrients, attractive and fragrant white flowers can be convinced to emerge. The problems become noticeable almost immediately.

First, the plant produces sticky nectar that actually drips onto furniture and is hard to remove.

Second, that sweet fragrance that is enjoyable outside can quickly become very overpowering as it wafts throughout the house. Anyone suffering from allergies will have to move the entire plant outside or suffer in miserable silence until the flowers die off in 7 days.

Spider Mites

These miniature menaces congregate out of the line of sight underneath the leaves and suck the juice right out of your healthy plant. Look for very fine webbing, yellowing, pale blotches, or the leaves drying out.

To eliminate them, cut away severely damaged leaves. Mix alcohol and dish soap in a water-filled spray bottle and apply liberally.

Soft Scale

Similar to mites but slighter bigger at 2-6mm, these tiny assailants target the sap directly running through the veins of the leaf.

Look for drooping leaves that are yellowing or have developed black mold, or a sticky honeydew substance.

To eliminate them, give them a sharp dose from a spray bottle filled with horticultural oil.

How To Stop Dracaena fragrans Disease (Dracaena fragrans Disease Prevention)

Having a disease infecting your plant is the last thing anyone wants, and the best method to stop that from happening is to prevent the occurrence in the first place.

Fusarium leaf spot and soft rot are some of the common diseases.

Companion Plants for Growing Dracaena fragrans

Even when the Dracaena fragrans is grown solely as an indoor plant it can benefit from having companion plants. These can be planted in the same pot as a filler, to add color, or to introduce different textures.

As a rule, no more than 3 different plants should be rooted in the same pot, but if the pot is large enough it is possible to add more.

Impatiens grow well in containers and will add the color portion of companion plants and, more importantly, they appreciate the same temperatures as the Corn Plant so will not wilt under the heat.

There are quite a few colors to choose from – blue, orange, red, white, pink, purple, and even yellow, and each has its own distinctive scent that is not in the least bit overpowering.

Incorporating the ornamental Sweet Potato Plant will add texture and contrast with its dark purple foliage. Similar to the impatiens flowers, it is hardy to USDA hardiness zones 8 -11.

There are other plants such as creeping jenny, coral bells, petunias, and more that are suitable for companion planting.² With a little research, it’s possible to find more options that will enhance the presence of the Dracaena fragrans in your home.
