Leaf symptoms are a yellowing to necrosis (tissue death) of the outer leaf margins. These symptoms begin at the leaf tip and progress down the margin toward the leaf base.


Does corn need fertilizer?

Pre-Planting Fertilizer

Sweet corn requires plenty of nitrogen and phosphorus throughout the growing season. An all-purpose fertilizer containing more nitrogen and phosphorus than potassium -- such as a 16-16-8 ratio fertilizer -- helps ensure healthy growth when applied to the soil before planting.

Only about four corn plants will fit with room to grow in a 12-inch (30.5 cm.) pot, so you may need several depending on available space. For this reason, it's best to select and plant just one type of corn variety. Corn plants that produce shorter stalks are a good bet for growing corn in pots.
