Moreover, why are the leaves on my corn plant turning yellow?
Cool weather can also make corn plant leaves turn yellow. Again, this is due to a lack of nitrogen. When soil is cool and wet, the corn has trouble absorbing nitrogen from the soil. So this doesn't mean there is no nitrogen in the soil, simply that the poor plants are too chilled to efficiently take up enough.
Secondly, does corn need lots of water to grow? Corn grows fast and needs lots of water to grow properly. It also has shallow roots that make it susceptible to drought. Soaker hoses will insure that your corn gets the water it needs. However, for a large planting, soaker hoses may not be practical.
Keeping this in view, why are the leaves on my corn plant turning brown?
Corn plants grow best in indirect but bright light. Direct sunlight can burn the foliage and result in browning. Too little or too much water can also cause brown leaf tips. Brown spots are usually the result of a mite infestation.
Should you cut yellow leaves off plants?
To promote growth and deter mold and pests such as fungus gnats, it is sometimes necessary to trim and remove dead or dying leaves from your plant. This helps the plant send energy to the healthiest leaves, as yellow and brown crispy leaves will not turn green again.
