Question
I have a corn plant and the bottom of the leaves are turning brown. What am I doing wrong to much water or not enough. Does it need more sun?

Answer
Sue,

These are low light plants that offer height, while keeping to a narrow space. At the top of the canes emerge green foliage that looks like a corn stalk. The foliage varies in color from solid green to light green, with green stripes.

The roots are close to the canes so water around each one. Because the water use is different for each cane, check around the whole pot. A sign of dehydration is wrinkling on the green stem where it joins the cane. Continual dehydration leaves you with crinkled withered foliage, and possibly Cane Rot. Over watering encourages spots on the new growth and yellow hallows around the very tips of the leaves. Watering it with "city water" with chlorine and flouride in it can cause leaf discoloration.  If that is your only choice for watering them then you must allow the water to sit in an open bucket for 24 hours before you  use it.  The chlorine and flouride will dissipate and the water will be fine. Be very careful not to overwater it.

Because of the shallow and small root system, the canes will become top heavy and lean over. To support the cane wedge a small object between the cane and the growing pot to secure the plant and keep it up right and stable. Do not lift these plants by their canes, this can cause damage to the root system. A root system damaged for any reason can cause leaf discoloration. Good luck.
