Corn Plant

Corn Plant (Dracaena fragrans “Massangeana”)

dracaena corn plant an effective indoor air purifier

Main Points:

This houseplant is one of many poisonous houseplants. Keep it out of reach of pets and children.

Its leaves are similar in appearance to those of corn. It will occasionally flower in white fragrant bunches. “Massangeana” is the variegated cultivar that sports a yellow band down the centre of the leaves.

The corn plant can survive in dimly lit areas, making it perfect for corners and hallways.

The corn plant can reach a height of 10 feet indoors; to stimulate new growth (or to rejuvenate an old plant), cut the plant back to about 6 or 8 inches.

The corn plant is effective in the removal of formaldehyde from indoor air. 

Care:

Semi-shade, but prefers bright light.

The corn plant is rarely attacked by pests — unless the air is too dry, in which case mealybugs and spider mites might descend upon it. Spraying a soapy mixture of water and dish soap over the plant should rectify the problem.

The corn plant requires moderate watering. Feed with liquid fertilizer regularly in the spring and summer. Water less often in winter and do not feed.  Keep the soil moist but not soggy. Water thoroughly once every 7 – 10 days or when the soil is dry- to-touch down 1-inch into the soil. The shallow root system of the corn plant are located close to the canes; therefore when watering, place the water near the base of each cane to ensure the roots absorb the water. If the leaves begin to drop or yellow, try watering the plant less frequently.  

If the plant displays brown tips, cut the ends with scissors, and adjust the living conditions of the plant (more water, less dry air, etc.).  Mist often and wipe leaves with a damp cloth to prevent insect infestation in dry air and to allow the plant to transpire freely. 

Grows well in potting soil; hydroculture is preferred.
