Perfecting the amount of light a Corn Plant receives is crucial for a long-lasting specimen. During the spring and summer, be sure to provide a brightly lit spot away from any direct light. Excessive exposure during this time will negatively affect the plant in the likes of sun-scorch and dehydration. Once the autumn kicks in, be sure to include an hour or two of direct light per day to get it through the dormancy period.
During the spring and summer, allow the half of the soil to dry out in between irrigations, reducing this further in the colder months. Those situated in darker locations must be watered far less than those located in brighter ones for the prevention of root rot. Under-watering symptoms include stunted growth, dry spots appearing on the leaves and yellowing older leaves; these issues are either down to an over-crowded pot, too little light, or forgetfulness. Over-watering symptoms include yellowing lower leaves, brown mushy patches developing in the stems and mouldy soil. For cases of root rot, take the plant out of its pot and investigate the health below the soil line. If there are visible signs of decay, click on this link to learn about the recommended steps to eradicate this problem. It's always better to under-water Corn Plants rather than over-do it, purely based on their impressive ability to endure periods of droughts.
Create a humidity tray to provide a moist and stable environment for your plant. If the surrounding saturation is too low or the heat too high, its foliage may start to brown over and curl, especially in direct sunlight. Hose the foliage down from time to time to hydrate the leaves and keep the dust levels down.
Feed twice a month during the spring and summer and every four to six weeks in their dormancy period. Avoid over-supplementation as a combination of excess fertiliser salts and burning roots will significantly affect its overall health.
Yellowing lower leaves are a clear sign of over-watering, usually caused by too little light. Although Corn Plants can do well in darker locations, the frequency of irrigations must be reduced to counteract the chance of root rot. People don't realise that a plant's root system needs access to oxygen too; when soil is watered, the air will travel upwards and out of the potting mix. A lack of accessible oxygen for the roots will cause them to subsequently breakdown over the oncoming days. Click on this lin to learn more about root rot and how to address it.
Spider Mite are small, near-transparent critters, that'll slowly extract the chlorophyll from of its leaves. Have a check under the leaves, most notably along the midrib, for small webs and gritty yellow bumps.

A further pest to look out for is Whitefly. Although these small airborne critters shouldn't produce too much damage, an infestation must be destroyed quickly to reduce the chance of them spreading. Click on this link to learn more about addressing these issues.
Too low humidity can cause browning tips with yellow halos on juvenile leaves. Although this won't kill your specimen, you may want to increase the local moisture to prevent the new growth from adopting these symptoms. Mist or rinse the foliage from time to time and create a humidity tray while the heaters are active to create a stable environment. The browning of leaf-tips on older leaves is wholly natural and is the product of extensive photosynthesis during its life.
Yellowing leaf-tips are the product of cold water or too much fluoride in the soil. This issue is caused by using tap water which hasn’t sat for 24hrs to alleviate the chemicals via evaporation. We’d recommend switching it for collected rainwater or fresh bottled water to improve its health, along with the reduction of its fluoride-count. The older leaves will always bear the scars of the past, but the new foliage should be as good as new within the next month.
Small, brown spots are typical traits of under-watering. Only allow half of the soil to dry out in summer, and liberally in winter - commonly caused by positions that are too bright or hot. If, however, the spots are deeper with yellow halos, it could be leaf-spot disease - often accompanied by a dark location and yellowing lower leaves. This disease is commonly caused by over-watering and could even kill the specimen over time. Click on this link to learn about how to address these issues.
Failed stem cuttings are the product of several reasons, with the first being the time of year. Corn Plants are best propagated during the spring, with cuttings taken in the autumn or winter rooting much slower.
The second reason could be the cultivation environment - is there enough light to read a newspaper? If not, improve the growing conditions by increasing the amount of indirect light, avoiding the threat of excessive direct sunlight.
Moreover, the size of the cutting will play a big part in its success; smaller specimens (3cm in length or less) won't root appropriately due to the lower amounts of stored energy.
For those rooting via water, the water must also be replaced weekly to ensure nasty pathogens cannot breed and decay on the cuttings. If the bottom of the stem is brown and mushy, discard immediately as the rot will spread onto unaffected specimens.
Maintaining too dry soil or over-exposure to the sun will also prove unsuccessful for those that haven't acclimatised to the drier environment. Although water-logging must be avoided at all costs, be sure to maintain moist soil throughout the rooting development (the initial six months) to quicken the process of establishment. To escape falling in the trap of dehydration, wrap the cutting and its pot in a transparent bag for the first couple of weeks. As there'll be a poor root system to soak-up vital water, its leaves will be able to absorb the excess moisture trapped within the bag for hydration.

Dracaena fragrans is a flowering species native to tropical Africa, in regions such as South Sudan, Mozambique and Tanzania. The genus, Dracaena, belongs to the Asparagaceæ family that holds specimens such as Hyacinths, Asparagus Ferns, Chlorophytum (Spider Plants), Sansevieria and Yuccas. The name derives from the Greek word for a female dragon 'Drakaina' that refers to its red sap and green foliage. The species' epithet, 'fragrans', refers to the fragrant blooms that was first coined by John Bellenden Ker Gawler. It was initially placed in the Aloe genus, before being transferred into Pleomele, Sansevieria, Cordyline, Draco, before finding its resting placed in Dracaena in 1808.

H1b (Hardiness Zone 12) - Can be grown outdoors during the summer in a sheltered location with temperatures above 12℃ (54℉), but is fine to remain indoors, too. If you decide to bring this plant outdoors, don't allow it to endure any direct sunlight as it may result in sun-scorch and dehydration. Regularly keep an eye out for pests, especially when re-introducing it back indoors.
The ultimate height is around 2.5m in height & 0.5m in width that can take up to 10 years.
Remove yellow or dying leaves, and plant debris to encourage better-growing conditions. While pruning, always use clean scissors or shears to reduce the chance of bacterial and fungal diseases. Never cut through yellowed tissue as this may cause further damage in the likes of diseases or bacterial infections. Remember to make clean incisions as too-damaged wounds may shock the plant, causing weakened growth and a decline in health.

Stem Cuttings (Easy)
Small, globular white or pink flowers are arranged along a thick flower shaft that'll appear horizontally towards the top half of the stem, lasting several weeks. It's highly unlikely that a domestically grown specimen will bloom indoors due to the unfavored growing conditions of too low humidity and consistent temperature levels throughout the year.
Repot every three years in the spring using a houseplant-labelled compost and the next sized pot with adequate drainage. Hydrate the plant 24hrs before the tinkering with the roots to prevent the risk of transplant shock. Add a thin layer of small grit in the pot's base and the lower portion of the new compost to improve drainage & downplay over-watering.

Keep an eye out for mealybugs, spider mite, scale, thrips & whitefly that'll locate themselves in the cubbyholes and undersides of the leaves. Common diseases are root rot, leaf-spot disease, botrytis, powdery mildew & southern blight - click here to learn more about these issues.
This plant is classified as poisonous. If parts of the plants are eaten, vomiting, nausea and a loss of appetite could occur. Consumption of large quantities must be dealt with quickly - acquire medical assistance for further information.
